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.
