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.
-
Hmmmm, a C64 emu sounds cool... too bad I dont have a nSpire :P
-
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.
-
cb/m? explain.
-
cb/m? explain.
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.

CP/M (http://en.wikipedia.org/wiki/CP/M)*
-
I semi-ninja'D you lol :)

CP/M (http://en.wikipedia.org/wiki/CP/M)*
Darn it, I must have confused it with that OS I dissected.
-
Actually, whats the resolution of the c64 screen?
-
320 × 200, 16 colors, sprites, raster interrupt. 16 colors could fit into the greyscale easily.
-
Wow more and more reasons to get an Nspire... This being one of them.

Well, assuming somebody actually makes the emulator ;)
-
Somebody should make a decent TI-83+ emulator first.
-
DrDnar there was one in the works, I even have a copy on my computer (using a 83+ ROM).
However calc84maniac lost the entire source code of all his TI-Nspire projects last Summer, after his laptop hard drive failed.
It would be nice to see a C64 emu and of course a decent 83+ emu, though.
-
That's one reason why it's always good to back up programs
However, losing the code to a program can sometimes be a blessing in disguise. I lost the code for my original Jack Game, but eventually I got over the "What a pain to make another" feeling and made one ten times better.
-
Yeah since that incident I keep reminding people here to backup. Calc84maniac had all his 83+ projects backed up on a flash drive, but not the TI-Nspire stuff.
-
I own nearly 20 computers so I've got just about everything backed up on something.
-
Wow that's a lot! O.O
Personally I backup stuff online, password protected in zip archives, on my two hard drives and sometimes a flash drive.
-
[offtopic]@GB 20? Holy crap man! O.O What in the world do you use all of those computers for? Are some of them retro or are you running them as servers or something? [/offtopic]
I guess a C64 emulator would be cool, but most people are probably more interested/familiar in emulating older gaming consoles instead NES, gameboy(color), SNES, Genisis, etc. (not that you can't use the C64 for gaming...). If one were to be made it would probably have to be someone who was a big C64 fan. :) Also, I'm not entirely sure, but didn't the C64 support a couple of resolution modes higher than 320 X 200?
-
There is in fact a type of C64 which does have games and cartridges.

It was UK only and not very popular. I want the original.
-
I was sure that C64 was worldwide? ??? Even Ranman got one I think and he lives in USA.
I also remember there was some device to play tapes.
-
I think he meant the cartridge only version was a UK exclusive. The C64 itself did have a widespread release.
-
But weren't every game on cartridges? ??? Or was it just some specific ones? I remember Ranman from USA played Ultima V on his C64.
-
the others used tapes, I think.
-
(P.S. Would an Atari 2600 emu work on the Nspire? That would be cool.)
The 2600 also uses a 6502 variant, so it's possible.
-
Actually there is an Atari emulation discussion thread at http://ourl.ca/10900 . I believe there was an older one before too, but I don't remember where is it.
Also isn't the 6502 the processor the SNES uses?
-
I know C64's were sold pretty much everywhere. I'm in the US and one of my Teachers has one. I have also known others who have ha them. When I read about them it seems as if they're worldwide.
-
@DJ: The C64 had a floppy disk drive addon, that I'd assume was the main method of software distribution. And no, The Snes uses a different processor.

Much different. I was also thinking a pre-emulation menu for loading cartridge ROMS or other media and a mid-emulation menu for loading floppy images (.d64, I think) and datasettes.
