C64 Emulator on nSpire?
« on: May 07, 2011, 07:18:53 pm »
I thought of an NES one before and it happened later thanks to Goplat, but the C64's screen would also fit, as would everything else in theory, but the real issue is: would anybody do it?

Since they have already emulated the MOS 6502 in the NES emulator, they would just have to emulate the C64's I/O.

Actually, the NES is missing the decimal arithmetic mode in its 6502 variant, and the C64 probably has it. That's not a super-huge deal to add to the CPU emulation though, I suppose.

The C64 has memory-mapped ports at addresses $0000 and $0001 :( (my emulator assumes that $0000-$01FF is pure RAM)

This would be really cool! I've wanted to get a C64 (I like old technologies) but now I'm planning on getting an Nspire clickpad so if a C64 emu is possible...

(P.S. Would an Atari 2600 emu work on the Nspire? That would be cool.)

My question being, can these things be made in C? Because we don't have so many SH3 Asm coders yet.

A lot of emulators are coded in C, although they're on the PC; C on nSpire is more dependent on the ndless version than ARM, so ARM would probably be more portable.

An 83+ family calc sort of functions like a stripped-down C64, but it's probably more like an old Z80 computer like one of those 8080s with CB/M.

Explain what about CB/M? It's just an old disk OS, but I was mainly referring to the fact that a lot of those use Z80. C64 actually had native TASM. From a quick check, the C64 uses Z80.

Yeah, the c64 uses a z80, but not as main core, afaik. So CB/M is just like DOS?

CB/M isn't exactly DOS, look it up for a full explanation; I don't want to put Wikipedia copypasta text walls here.
