Commodore VIC20 - ROMs

briankross

Hello,

I'm just getting in to rediscovering an old favorite from way back, Cosmic Cruncher!

I've found these ROMs, but I can't tell if they're all different versions and need to pick one to run, or if they're in sequence where I need them all and need to figure out which one is the first to run.

I'm referencing Commodore 64 in the wiki.

Cosmic Cruncher (1982)(Commodore)(NTSC-PAL)[a][A000].crt
Cosmic Cruncher (1982)(Commodore)(NTSC-PAL)[A000].crt
Cosmic Cruncher (1982)(Commodore)(NTSC-PAL)[a2][A000].crt
Cosmic Cruncher (1982)(Commodore)(NTSC-PAL)[a3][A000].crt
Cosmic Cruncher (1982)(Commodore)(NTSC-PAL)[a4][A000].crt
Cosmic Cruncher (1982)(Commodore)(NTSC-PAL)[a5][A000].crt
Cosmic Cruncher (1982)(Commodore)(NTSC-PAL)[f][A000].crt
Cosmic Cruncher (1982)(Commodore)(NTSC-PAL)[t][a][A000].crt
Cosmic Cruncher (1982)(Commodore)(NTSC-PAL)[t][A000].crt

Any ideas?

Have you tried just using the mega-cart image?

I just use a single entry in my c64 menu.
I then launch a image of the megacart.

It has 99.9% of anything you want to run on the vic from a joystick driven menu.
And it works for either pal or ntsc emulation.

The command to launch is.

xvic -cartmega mega-cart.rom -mcnvramwriteback -mcnvramfile mega-cart.nv

If you don’t have the nv file, I just created a blank file and let the emulator fill it in.

Later,

I have not tried using the mega-cart image, something I need to download using my google-fu?

I'm making a backup image of my system, then I'll try this.

Thanks!

I tried running this command while in xvic and got an out of memory error. Is this run on the rPi via ssh instead? (new to this emulator)

Create the mega-cart.nv blank file in /home/pi/RetroPie/roms/c64 ?
