Re: [stella] 2600/GBA Programmer Needed!

[Glenn Saunders <mos6507@xxxxxxxxxxx>]

Given that the only existing commercial PS1 emulator for 2600 frame-skips 
(Activision Classics) and that's on a 33mhz 32-bit machine, and given that 
the first time I saw a 2600 emulator run at full speed was on a 486DX100, 
I'd say it's got to be impossible to reach 60fps on a GBA 2600 emulation 
without somehow porting the games over one by one.
