I tried to use maprom function with 3.1 ROM. But without success. Only this version doesnt work for me - I'm getting blanc screen and late no signal to monitor. 3.0, 3.x. , 3.1.4 works fine. I'm using newest version of AcaTool. This ROM file works great with WinUAE. CRC32 of this file is fine = stock Commodore 3.1 ROM.
I have inserted 3.x phisical modules from Cloanto.to my A1200 rev 1D1. Anyone could maprom C= stock 3.1 ROM successfully?
