Hey, I went with a vague title so I can reuse this topic in the future if need be.
I'm trying to emulate Treasure Island Dizzy, and I've got a rom, probably from atarimania.com. In Steem SSE 3.9.1, it works with model STE, CPU speed 8 MHz, Memory Size 2 MB, and tos104uk.
In Hatari 2.0.0, under the same settings, it doesn't work. The main theme doesn't play, and the colours are off.
