Actually I don't care about OS4 or the other NG variants for this game.
This time it's about AGA 020 hardware banging fun. If it works with RunInUAE, fine, if not, bad luck. I'll just take care that it works with all 68k accelerators for which I get testers for, and WinUAE

@all
Technical note: when testing the game on a Blizzard 1230 IV and a TF030, I got eventual screen corruption as you'd eventually get when triggering COPJMP1 when the blitter is active. The blitter was eventually active indeed, however, for copper-list switching I only rewrite COP1LC. The workaround was to switch off blitter DMA at the very end of the copper-list. I'm not too much into hardware bugs and don't know if this is a well known issue, maybe that info is useful for others.
