It was a bit of a headache, so I hope that somebody might find it useful.

What’s Ultimem, and what does the library do with it?

Seems like a neat thing. I'd love to have RAM at $a000 and ROM at $6000.

This should do:

Code: Select all

*ULTIMEM_CONFIG2 = ULTIMEM_CFG_ROM << 4 | ULTIMEM_CFG_RW_RAM << 6;

VICE can emulate the UltiMem down to the metal (Cypress S29GL064N). Unix user can set it up quickly.

Code: Select all

dd bs=1024 count=8192 if=/dev/zero of=empty.img # Make empty ROM image.
xvic -ultimem empty.img -umwriteback

But I suspect it's not 100% accurate. Got things that run on VICE now but not on real hardware.

you should report them

Was under the impression that software engineers are supposed to come up with more detailed info than "doesn't work". Will take some elbow grease to find out like making miles with that SD card. This lib should work tho.

Obviously some info detailing WHAT doesnt work would be kindof required =D

I dunno. INGLE, that wannbe VIC Windows, does not boot. In addition I got an early version of the expansion and I'm about to grab another. Does not affect this library though.

Sorry I didn't see this earlier. It's very much appreciated!

Let me know how I can help get this working on real HW.
