Whoever said Final Fight or the Lotus games work on an unmodified A1200 needs to learn use a REAL Amiga.
All those games have issues regarding the 1200s Kickstart ROM at the least. You won't be able to make them run unless you softkick your A1200 into an older kickstart (like 1.3), or installing a rom sharing switch.
Softkicking is easy. You can get a softkicking ADF on www.commodore-ale.com (if they didn't remove it), which will boot your 1200 in kick1.3, and allow you to play Lotus and others. Some games will still comlain about the 1200s chipset, and might not work, but most times, thesoftkick will work just swell.
If you cant find the softkicking ADF in ALE, let me know and I'll send the stuff to you.
