booterrom.bin (32 KB) Hm, problem found... I tried to start/reset VICE in 80 columns and emulator hangs... really don't understand now. I mean there's no change between 40/80 active display: - status of 40/80 key - address 215 = active screen Any other changes? I attached updated ROM. Miro

Yeah, the MMU makes programming more difficult than the C64... I guess one reason c128 was not so popular... but on the other hand the MMU makes it SO MUCH more powerful (a good value, IMHO).

I like MMU for its functions. My problem in case of ROM I didn't wanted to change any MMU config for not full understanding it - I sit down and search internet about ROMs for internal or external socket and I found all what I wanted, now I know that better than to be afraid is to ask or search and read. In case of The Ace - it is impossible to work without bankswitching...
I want to decide which way to select now: programming from BOOTER new BIOS or begin creating PC tools for new Drawer?
I'll post it on blog and all comments and suggestions are welcome...

Never assume that the bank is on the one you want. I learned that the hard way programming.
