Instead of calling it the FXPAK call it the "Solid Drive 2 SNES" this way in the communities you can still say SD2SNES and people will still know what your talking about.
You sound like a lawyer. :D

Re: Theoretical 32 bit 65xx CPU idea

High: ZZYYXXAA ;register size selector (both 10 and 11 are 32bit)
:cry: :cry: :cry:

Can we get away from the variable size registers concept?

How about more register with different sizes?

Re: Squish!

Played a little bit. I like it.

Initial suggestion: give the level more contrasting tiles as it sometimes looks like the character is standing still.

Will play more and report.

Re: Lizard Source Code

As a future project, I was thinking we could pool some money and create some sort of publishing unit for nesdev titles for the switch, ps4 xbox.

No idea how viable this would be, or how transparent it would be for the ones involved.
