On the MAME front, PGA Tour isn’t even emulated as far as I know. 90% of the Golden Tee Fore questions can be answered by telling people to switch the resolution dipswitch to low or get a faster Intel processor. Hardly anyone discusses the 3D series at this point and I’m not sure I’ve ever seen anyone discuss the first two GT’s.
While questions do come up regarding the actual hardware on these games, it’s not excessive and honestly, the KLOV forums are probably a better resource for that.
There are enough driving and shooting games to justify their own forums but this is just way too limited. This is coming from someone who plays Golden Tee way more than anything else.
