Hi Jonathan,
how are your plans to support 6502 in SDCC going ?
Last week I got to TurboGrafx-16 game console and currently thinking how to
program it in C. My idea is to create HuCard with SD CARD and RAM. Simple
bootloader chooses the game from SD card, loads it into RAM and runs it.
This sounds really like long way so C compiler would be helpful.
Regards,
Vaclav

Apparently it is quite similar, but the HC08 has no Y register, but has
a lot of added instructions the 6502 lacks. I'll really look at the HC08
port as a base for my attempt to port for the 6502.

Exact, the 65C02 has some extra instructions. It is used in the
TurboGraphix-16 / PC-Engine video game console.
