all of my arcade roms seem to be fine, ignite full screen @ 720p is very good, i have no issues with the interface and believe the background work that has been implimented to drivers, filters etc has made a real performance difference, Anyway the reason im posting is to say that the lightgun games still work and dare i say seem more accurate due to the decent scaling filtering. I only have a few gun roms from back before CoinOps as the rest were dire or didnt work / calibrate. The roms i have worked worked before CoinOps so any other code added doesnt seem to have done anything really unless anyone can tell me which gun roms have been improved in this build. When i have my PC back online i will check those roms that didnt work. Working (worth playing) LightGun Roms Alien 3 The Gun, Bang, Beast Busters, EggVenture DX, Gun Buster, Lethal Justice, One Shot Kill, Operation Thunderbolt, Operation Wolf (cross hair fixed extreme left or right), Police Trainer, Sharp Shooter, Space Gun, Terminator 2, Tickee Tackats, Under Fire, Zero Point, Zero Point 2, Zombie Raid. If anyone knows of any other roms i should check out feel free to enlighten me.
