Commodore 65

Does anyone know if there is an emulator available for the Commodore 65?

It would be nice to have a play with one, seen as they are almost impossible to buy...

MESS includes a C65 driver, although it's been a while since I've checked (and when I did, it was buggy). From the site, in the list of supported systems:

Quote:

C65 / C64DX (Prototype, German PAL, 910429)
C65 / C64DX (Prototype, NTSC, 910111)
C65 / C64DX (Prototype, NTSC, 910523)
C65 / C64DX (Prototype, NTSC, 910626)
C65 / C64DX (Prototype, NTSC, 910828)
C65 / C64DX (Prototype, NTSC, 911001)

Got the emulator working!

Does anyone know of any software/demos available for this system?

Yes I got that error at first then I copied all the different C-65 ROMS I could find into the BIOS folder (leaving as .zip files) then it seemed to work fine!

There were six roms I copied, all from here http://www.geocities.com/messroms/

(although the emulator does say that the roms don't function correctly, although they seemed OK to me ...)

Apparently the C65 is compatible with many C64 titles, but I don't know how to get the emulator into C64 mode, or how to attach .d64 files, if that is at all supported ...

type GO64

To attach an image go to devices and mount it on floppy drive #1.

I sure wish I had one of these babies.

meh. I played with one once.... read the technical manual, had a look at some small demo routines that Paul Gardner-Stephen had written for it (including an amiga iff slideshow from memory).

On the whole I wasnt all that excited. I guess its the overriding feeling that youll probably never have anyone to share the experience with, since noone else owns one Wink

Now the C=1 excites me a lot more - but Im waiting for it to stabilise a bit before committing.

The 65's 64 compatibility is not as good as the 128's. From Cameron Kaiser's Secret Weapons of Commodore, referring to 64 compatibility:

Quote:

Well, it was a nice thought, anyway; the 65 is 64 compatible, but not in the sense that the 128 is 64 compatible. The 128 basically carries a 64 inside of it (therefore 99.9999999% compatible except for programs that mess with a few select locations peeking into the 128 hardware) with all attendant ROMs, quirks, etc. The 65, on the other hand, actually emulates the 64 while keeping all its enhanced features active (runs at the lower clock speed; emulates the BASIC [version 2.2 ?!]). Because of this, the 65 is really only around 75-80% compatible with 64 programs. Demos, copy-protection schemes and cracks depending on NMOS artifact opcodes in the 6510 will die or misbehave; there are probably timing difficulties as well.

I have tried mounting a .d64 image but can't get it to work.

I tried LOAD"$",8 but got missing file and then I realised it was set as decvice 10 so I tried LOAD"$",10 but the system locks up everytime. It also locks up if I try to mount a .prg file ...

Any ideas?

Got it working, thanks Rubik Smile

I have no idea what the .prg files are (I'm sure I've seen .p00 files before?), but I assume they're disk images for the onboard 3.5 inch floppy drive? Hence, the quick boot?

Mounting .d64 images to the two drives doesn't seem to work - the machine (well, emulator) can't see anything there. I'm not sure how BASIC 10 runs, but it can't be that far from the C128's BASIC 7. Disk loading responses are certainly different.

It doesn't matter whether or not I load images in '65 or '64 mode - nothing works.

Does anyone know of any online manuals for the C65? I'd like to learn a little of the basic. Surely someone has manuals out there?
