We are continuing to work on it :)
The reality is that we are a bunch of volunteers working in our spare time, which is limited.
Volunteers helping out with some tasks would be a great help, as would further donations that can allow us to spend less time worrying about how we might do some task, rather than just paying to get it done.
Right now, I am working on adding support for 6502 illegal-opcodes, which is quite important.
I'm also finally finding some time to stick my head in here in the forums, to answer some of your questions ;)
