Off the top of my head: Out Run, Final Soldier, Daimkaimura (SGX), Granzort (SGX), Darius Plus, Toilet Kids, Hana Taka Daka, Gradius, Salamander, Coryoon (if you have a kidney to spare), Götzendiener (SCDR2), Circus Lido, Star Mobile, Ai Cho Aniki (SCDR2), Rondo of Blood (SCDR2)
Didn't put any crappy titles in there but there should be a few of these as well
