I could put a heatsink on it, but if it was needed I would expect it to already be there, right? My A600 is pretty standard, except from a 1MB chip trapdoor expansion and a CF card located left of the ACA620, but not touching it.
The ROM is a normal one, not from Cloanto (don't think it would even boot as it would be garbage). I have used the same ROM with skick where it works fine (it checks the checksum so I assume it is fine).
Edit: I have ACAtune 1.7 (took a while finding it) and the commandline I am using is 'acatune -maprom hd0:devs/kickstarts/kick40063.A600 -maxmem', so nothing fancy. Think it might work better with a A1200 KS?
