The optimal "old-game-configuration" would be, ROM 1.3, OCS-chipset, 512kb chipmen (no fastmen or other type) and at least try 100% sound-emulation. Also set CPU-emulation to 68000 and no cache... everything to make it match the A500 as much as possible. Save that configuration to A500 or whatever. I'm using one configuration for AOS and one for games. That's working great! Actually I'm using my real Amiga most but when I use WinUAE this is what I'm using. Check EVERYTHING and it shall work
