MEGA65 FORUM

Does anybody actually want Commodore 65 ? / some destructive ideas

append delete Chicopy

If you finish this project (please please do..) and it would be successful, then I guess it could be only for one reason - 99% of people would buy it to play C64 games.
Possibly there really exist the 1% who is interested in C65,
I don't understand why, I have never heard about it before discovered Mega65, I am unable to find any list of games made for it and according to Wiki only 50-2000 pieces were sold.
Do you expect anybody would waste time and write new (& better) games for C65 ?
Why ? Spend months making games anybody can copy for free ?

I also have doubts you will ever be entitled to sell your clone of C65.
I guess there is still somebody who owns rights for all Commodore stuff, despite the company doesn't exist any more.

If you think there are not any legal issues threatening, then I would ask you to consider following ideas:
- the fact you are trying to make the Mega65 physically the same as C65 must make it very expensive; if your version supports SD cards, then there is no reason to use 1.44 Flopp-drive;
also no reason to copy the C65 keyboard
- why not to make the PCB as small as possible (cheap), omit Floppy-drive, design simple little enclosure, use PS/2 or USB keyboard, add some wireless transceiver to enable design of wireless joysticks = thats enough for the 99%...
- I guess FPGA soft-processors like MicroBlaze or Nios are much more powerful than the processor used in C65. There also exist compilers for them and many people use them. Couldn't the video & sound circuits you cloned be powered with this kind of processor ?
I personally program 8b microcontrollers but if I could choose, definitely would prefere assembler programming with comfort of 32b architectures.

Anyway, I wish you great success with Mega65 and hope it will be ready soon and for reasonable price - otherwise, you know, emulators do the same job for free and work ok in many cases..

Kind Regards

Hi!

I agree!
I'm one of the 1% mentioned.
Really I want to work with C65 clone and it needs really not physical copy for retro feel.
It needs only to get it work.
When I saw latest posts on Paul's blog I see it goes far away from the goal - make C65...
Phone, even C64 mode has more functionality than C65 mode - again may people want C64 in Commodore 65 - C64 is not only one and even not best Commodore computer.
Also - these reasons created my decision - I sold Nexys4DDR (used was only for M65, Apple IIe and Sam Coupe) and like you told - emulators does the same. BTW. I have Sam Coupe and Apple II+ (saly not IIe) in MiST.

M65 projectgeos wrong way - far away from its goal.
Also this reason was at discontinuing M65 support of my The Ace OS.
Now I can develop it faster 'cause targets are only two - C128 and C64.

Many men will crucify me for these words, but everypbody can have own opinion and I have too. Written above.

Hello Miro,

I hope noone crucifies you for your words, and I certainly wont.
The whole point of the retro scene is that it should be fun for people with their volunteer projects. If it stops being fun, then don't feel any obligation to continue. It also makes sense for you to focus on fewer platforms, as scope-creep is always the enemy of us all getting things finished.

It is important to note for the phone concept, which is really much more hand held console that happens to also be a phone if you want it to be, is a side project where we make good use of student projects, without complicating the critical path to the desktop computer. The desktop computer remains our main priority.

Hello Chicopy,

You are quite right that there are other ways to tackle the retro experience. What you have described is more or less what the C64 Mini has done: Use a cheap, fast 32-bit modern processor, and emulate everything. I won't hide that that is cheaper than our approach, but we really want to recreate the complete computer experience. As I mentioned to Miro, everyone has their own tastes and choices, and doesn't have to think any particular project is completely right, but hopefully it doesn't stop us all enjoying hearing about all the projects going on in this space. For example, I have no interest in buying a C64 Mini, but I like to hear how people are using them in nice ways.

Paul.

I, for one will be buying it.

Perhaps it doesn't make logical sense, but then I don't think it needs to. It's an achievement, and scratches a retro itch.

People are still writing games for the C64. It will be interesting to see what is written for the C65.

A 65 gamejam here and there might be something.... :)

@ Chicopy C65 is never "sold", well, at least not the way, like C64, etc ... As project C65 was never finished, all the existing units are "developer units" which actually a bit different software and hardware inside for almost all of them ... So not even a common C65 "standard" for real existing C65 units. Creating a C65 clone (albeit a further enhanced, thus M65) is actually to grant a wish to have a "ready" C65 which was not even the case in reality. So partly, these are for people who are interested in these kind of dreams. So it's hard to compare, how many software written for that, etc, you wrote ... Of course almost none, it's a never finished project. That it's all about to think this way, to have it finished _now_ inside the M65 project. Surely, it's for people more interested these kind of things/dreams, it's not for everybody! OK, actually, there are many other factors here as well ... Like the added value over the C65-level, the possibility to create a computer which can be used even to learn more on computers etc etc. You can argue the point of many other projects as well, like C=1 and C256 Foenix, especially the second, where they create a "Commodore-like" computer not even aimed to be compatible with any existing and/or planned Commodore machines (M65 "at least" wants to be compatible with some finished C65 state and even gaining more C64 compatibility)! But again, there are different people, some of them are interested in these as well, including me too. Some people say, that's insane. Surely, even my wife says, that real C64s etc are mad to be used now, since they are so "insane", even cannot be used for watching youtube videos, etc. That's true. The point of retro computing in general is over the "logic" and much more a "personal love" ... Any existing kinda modern PC will be much powerful than any Commodore machines ... That's a much more emotional topic than just this.

@Miro: "C64 is not only one and even not best Commodore computer.". The first statement is true, the second is ... hmm pointless. How do you measure being "the best"? So, any Commodore machines nowadays are "lame" since cannot be used for the same as a modern PC. Again, "the best" is more a personal taste and _love_ and not so much a logical benchmark/specification/anything to check out ... At least nowadays. Surely, back in time, in that era, it made sense to say which is the better technically, which one to choose, and so on. At least more sense than now. Let's face it, for many people, the love towards "old computers" is more like a personal "intimate" thing. For me: my first computer for C64. So C64 has its place in my heart, regardless of any other statements about its "hype" or "capabilities" or anything. And it does not mean I don't like other "retro" computers than C64, for sure.

In general: even with some attraction to "retro computing" it does mean other things for different people. First, emulators. I can't see any point buying/using a C64mini for example. It's an emulator. I can run an emulator on my PC too, for free, what's the point here. But I admit, some people is not interested in configuring software-distributed emulators, don't want to power on a PC for it etc etc, and wants a self contained device, for that purpose only, even if it's "only" an emulator. Nothing wrong about that. Some people like "more hardware level" stuff, and some of them can't even accept FPGAs saying "it's cheating, it's not the very same any more by its internals". I can't even imagine a scenario to have a project in this topic which suits everybody, you see .. But as far I can see, having a "real" (physical) machine, which is not an emulator, having open source VHDL for FPGA implementation (which makes possible even for others to port it to other FPGA boards if really desired ...), and even having a hopefully maturing emulator (well, that's my task ....) can create a situation where many different people can find their needs within the project. Again, maybe not, we are not the same, even then there can be other feelings, for sure.

Gábor I understand, what to write:
1. C64 is not only one Commodore computer - true but many people thinking - we don't want other.
2. C64 is in eyes of users the best - why? Even M65 project has in C64 mode again more functions and looks like same fate like my beloved C128. Of course it is personal feeling or love.
Me personally began with Didaktik M (ZX Spectrum Czechoslovak clone) and then came C64.
3. C64 Mini is what you say - emulator and this I want not (not for C64 exactly) - emulator stays emulator forever.
4. M65 project is not emulator and this I like, but now the way to finsih is harder for developing other variants.

What to say?
I'm watching Paul's blog since I found it on Google+ and it is lot of years.
I saw first steps.
Me personally cannot to say that he's slow 'cause my OS The Ace is developing much more time like M65... but for many reasons I have not enough time, sadly.
I hope that I will have more time, currently I can at developing to be around 2 days in week... sometimes 1 day and sometimes no one day in week... So, all people watching progress, please don't think that I will not come, please all wait still any time.

hank you for all.

Miro, since we had some talk otherwise too, I may see the problem of yours, and as always, it's kinda hard to say someone is right or wrong, it's not about that at all ...

The "problem" here, that M65 is focused on a dream-come-true (at least for some people, ok), ie a modern clone of a never-finished C65. Ok, since then, it got many other things, but its root is the same, still. And given by that, you can't just change the fact, that C65 at least had some low degree of C64 compatibility. You cannot force other machine here to be compatible with, it would be very different project than M65/C65. So what I wanted to say, I am not sure, what you would like then, since that is the roots and the origin of the project itself. Surely, being an FPGA based solution, you can at least write other "cores" to implement totally different hardware, but you can't just mix into the project directly for C65 and/or M65 "mode" as such easily. Or if you want to "cut off" C64 from M65 since "we don't want another" then it's just odd, since it's part of the original design as well, surely with quite limited compatibility, but still. It's like (ok, not really ...) cutting off C64 from C128, since VIC-II and SID is "so much C64" (and to be more precise, C128 has a much-much-much better C64 compatibility mode than C65 ever would be ...), let them kick off :-P It would be a kind odd situation. I admit it was not the best (but about the worst ...) "resemblance", but anyway ...

The other problem, as far as I can say from hearing news, etc, many people wants M65 in the future because of "it can be used as a C64 too". Well, yes, you can hate this. But it's really shrinks the "target audience" of M65 if you leave any further work on C64 compatibility, even if we know, C64 compatibility may be not 100% ever, unlike using a C64-specialized core, as should be otherwise. Life is just that odd. And yeah, it seems here I contradicts myself, when I said that it's fine to even create something which is not compatible with anything at all (like C256 ...). Well, maybe there is no "white" and "black" in opinions either, just shades of grey.

About Ace: I'm not really understand the situation, but it can be my fault. If you ever wanted to develop it for "C65" it wouldn't change that M65 basically is that as it roots, or what did changed, what is the exact reason you call "wrong way for the project" then? It would be that to break several barriers of the C65-compatibility, since then it's nothing to do with the original goals. But yes, lack of time, that's a kinda logical answer, I know that too, maybe too well :( :( :( :(

append delete #7. MIRKOSOFT

Gábor, you maybe understand me not fully.
I said not to cutoff C64 mode. Truth is truth - it is feature of C65.
But focus development to C65 mode.

C256 - this is really perfect project. I'll send to you details later.

The Ace - I throw not written code for M(C)65 into scrap. I paused development this way until will be not clear what it will be. Currently it is very unclear and limited resources is main problem, even public builds are main problem.
I know that core is possible to build by online source. But really watch changes and build every core is not so small amount of time. Why Paul releases not more public builds? Even at beginning was promised registering in subscribe about new releases - nothing happened.

Miro

Hello,

The main reason we haven't make a lot of public bitstream releases is mostly that it feels like we are always fixing some major problem, and there rarely feels like a right time to release a new version. We have no real problem in principle with doing so, however.

Paul.

append delete #9. LGB

Miro, that's interesting. As far as I can see (but I can be wrong!!!!) development on C64 mode (ie further enhancing its C64 compatibility) within the M65 project does not get too much developer resources compared to C65/M65 level stuffs, at least I am not aware of this would be the case. So this is one reason I cannot understand what you mean about "wrong way for the project" when it didn't get too much attention anyway yet, just maybe some plans were talked/written about and such more, than actual work. So, I see exactly what you wrote: the focus is on non-C64 things more. Surely there was things, like implementing "NMOS illegal opcodes" in VIC-II I/O mode and such to enhance the compatibility but I really cannot see that it got so much attention and work from developers that it had negative impact on things for C65/M65 side, that is lack of enough developer resources there, because of the "too much" time spent on "C64 mode". But surely, I am not exactly the person you should accept this information from, that's true :D :D Indeed, C256 looks a nice project (and thanks, btw) but, its target audience is very limited, I worry a bit if this project dies eventually because of the "too new" thing created, has no connection with anything (ie, on some scene parties, there are DTV demos time to time, but DTV was somewhat popular at least because of its C64 compatibility at the first place and then only the extra features ...). But I wanted to be wrong here SO MUCH! It's nice to have something completely now, as well!!

append delete #10. gardners

Hello,

On C64 compatibility we are actually spending a bit of time on this right now, so that the CPU/VIC timing is more accurate -- enough for most games to run without significant graphics display problems. I'll likely do a blog post about this soon.

Paul

append delete #11. LGB

Paul, thanks. Just I am a bit lost here, as others seem to consider working with the C64-compatibility the "wrong way" for the project. I think it's just faaar much more work on the non-C64 things in the M65 project than the C64-only "parts". But surely, I can be wrong. Of course, aiming the 100% C64 compatibility and no more care on anything other ... well ... that's of course would be a bit "wrong way" compared to the original goals of the project. But it's a hard question, as - it seems (even I read Hungarian blog posts on this) many people waiting for M65 that "it's cool", but "mainly I would use for C64 programs". Which is hmmm, kinda problematic again :-O

append delete #12. MIRKOSOFT

Long time I was waiting in development of The Ace for CPU switch for C64 mode from 65CE02 to 100% compatible 6502 - that posted Paul on blog and it was very high chance to apply C64 part of core directly without dramatic changes for C64 mode.
Really why I'm talking about C64 mode as wrong way:
- developers will benefit only from enhancements
- native C65 mode will fade (same as C128 and DTV)
This makes from chance to get new C65 mode software less possible.
Also - C256 project avoids it - new computer and really can be not successful 'cause C64 scene won't accept anything other. The same was with TED Series.
I hope that C128 community will support much more C256 than C64 community.
And when will be anything new and all will see benefits, it can allow to look more people forward. BTW - C256 has same processor like SCPU... so it's 65K family and in emulated mode it is x65 family (of course 65C02)... and more and more.
We can talk long time what is or not wrong, but it is opinion of each other.
I hope that M65 will be finished and I'm afraid about fate like C128 and DTV.
I hope that C256 will not have fate like TED Series and not afraid about fate like C128 and DTV and even maybe (please noooot) of M65.

To be clear: We are not aiming for 100% compatibility. We don't expect the majority of demos to run correctly, for example. However, it is important that at least the majority of games run well on it, since we know that this is a lot of how the machine will be used and judged.

Yes, there is a risk people will only ever use it as a nicer C64, and that is up to them. I don't worry about it too much.

The C128 mode problem is actually quite different: You couldn't use all the C128 features from C64 mode, so software ended up basically using just C64 mode, and perhaps 2MHz mode in the vertical blank period. The C65 approach is different: You can access all the extra stuff from C64 mode, so it is much easier to ease across to writing software that uses some nice extra feature, and then another etc.

That was one of the reason (not the only one, I'm one of the C65 'dreamers') what sold me on this project!

It's howthe C128 should have been but wasn't.

append delete #15. gardners

Yes, it is a bit like the AGA Amigas being backward compatible with ECS, so you could use additional features as you wished, without being forced to abandon your prior work. In that regard (and also the timing and even features of the C65), the C65 can almost be seen as the "AGA C64".

That's very cool! :) Great way of articulating that for that part of the mega65.

append delete #17. MIRKOSOFT

Paul, see you what you wrote?
In one magazine title of C64 fans was at that time:
C65 - Lost son of Commodore 64...

That's really like 'AGA C64'

I know it is only about playing with words, but it looks from your from your words that you're developing new revision of C64... This has no sense, produces only my fear of M65 fate, so better for me and others to close this thread to avoid fear, hate or love...
Miro

append delete #18. gardners

That's okay. I don't worry a lot, because the whole point of the C65 was that it was an evolved C64. The M65 is just that, with improved backward compatibility, because real C65 were so incompatible as to be almost unusable except for a few specific titles. Whether people only use the M65 as a C64, a C65 or an M65, I don't really mind. What matters to me us that people have fun using it, in whatever mode and for whatever purpose. If it can make people from all three camps happy, then I am happy.

If we are worried about the M65 being a commercial success, then we should all give up now -- because that is not the point, and it would be a totally unreasonable expectation in (almost) 2019. It is all about the fun. Do whatever brings you the most joy in your hobby time.
