I tried "Turrican II - The Final Fight_Disk1.adf" in A500 rom 2.0, 1Meg chip, NTSC (this is normal A500 converted to A500+ with full ECS, I made a switch that I can boot in to PAL, I tested this game in PAL and it works fine too, music seems slower a bit) and A1000 Kick1.3, 512k chip, 1.5 Meg fast, NTSC, both work fine.
