- cmrdporcupine 7y agoThis is all being worked on. Someone is writing a BASIC, others are building OS-type stuff. I've been fiddling around with OS and language type stuff. It's its own platform. It's not like there's much from those old machines that'd be all that fun to run these days anyways. The only thing I'd want from the IIgs would be the excellent ORCA series compilers. 65816 is a challenging platform due to lack of higher level language tools, and the oddities of the ISA (switching back and forth between 8 and 16 bit register modes, etc.) but this could be surmountable with contributions. Several people including myself have attempted a LLVM backend for 65816, but nobody has finished it. Sure would be easier with the assistance of someone who was an LLVM expert.
- jacobush 7y agoIt would be fun if Flight Simulator II could be made to run. 1 fps on original C64: https://www.youtube.com/watch?v=0HWzJMFeQv8 https://www.youtube.com/watch?v=0HWzJMFeQv8 Much faster on 65816 CPU. (But video footage from an 8-bit Atari modded to use the 65816 CPU.) https://www.youtube.com/watch?v=yLGchhLGAE0 https://www.youtube.com/watch?v=yLGchhLGAE0
- cmrdporcupine 7y agoProbably not easy to port without original sources, and even then, probably difficult. It would probably be faster on c256, as there is a math coprocessor for mul/div.
