Oh, it is simple bank-switching hardware: "Ability to run up to
254 - 8K ROM based Vic-20 Cartridge games or utilities". This smells to
me that nothing is compressed, and a 4-kilobyte cartridge will use up
8 kilobytes of ROM. The total ROM capacity seems to be 2 MB.
The 4 MB flash on the cartridge I built can hold pretty much all Vic-20
software and cartridges. Everything is packed tightly: there's no
wasted space on the flash.
Ah, I should finally grab myself by the horns and finish that image
generator. I already had a working one, before I decided to implement
subdirectories in the menu firmware. Like Jim Brain wrote, kids are a
factor too, and mine will soon need some good Vic-20 games to play with. :-)
