Thanks for the moral support. You always need that when you take on
disassembly of 8K of machine code.
I think you might be talking about hacking the old Taito arcade
machines. And yes, that would be a fair analogy. Although I am not
writing an emulator like MAME.
What I am actually doing is trying to put additional features into the
Poly and EX. We already know that ROM capacity is the major
restriction. RAM is also rather short. So adding 8K of RAM and 8K of
ROM is going to be necessary. But once we get that extra memory we
will be in a excellent position to start adding some great new
features. Although we will have be careful not to overload the CPU itself.
How about a fourth EG so that noise the filter are separately
controlled with their own EG's?
And what if we had a fifth EG for resonance. And a six for Ring Mod.
And programmable 24db/12db filter setting?
