I had issues with my 2b and 1232, yes some (probably most) games would cause lock-ups/crashes on my unmodified motherboard.
mostly fixed by removing a couple of caps from the back of the mobo, 99.9% of titles work for me.. but gloom and wing commander are both unplayable with the ACA, wing commander just craps out as soon as it starts scaling sprites and gloom has issues with missing level geometry.
Just to be sure, theres only 1 wing commander game right? I never played it in my life, but decided to give it a go on my ACA1232 33mhz. I used WinUAE to handle the ADF images, and then installed it to a temporary partition. I then ZIPed everything up and uploaded it to my space at the university. Loaded up my Amiga 1200 and grabbed the file and uncompressed everything. Game runs great. No timing fixes on my A1200. It is a 1D.3 revision.
