ROSS CRT type support #428

Open TomCat666 opened 2 months ago

TomCat666 commented 2 months ago

Would it be possible to add ROSS CRT type (23 decimal) support on U64? It was a standard type here in ex-Yugoslavia with most cartridges in that format. We would love to see them working on our Ultimates.

You can find the sample crt files here: ROSSOFT.ZIP

"Ross" Cartridge
- 16kb or 32kb ROM
- 16Kb ROM mapped in at $8000-$BFFF in 16k game config
- Any read access to $DE00 will switch in bank 1 (if cart is 32Kb).
- Any read access to $DF00 will switch off EXROM and GAME.
