Arcade Hits: Shienryu Choaniki: Kyuukyoku Muteki Ginga Saikyou Otoko Dezaemon GaiaSeed: Project Seed Trap Mobile Light Force Sonic Wings Special Zanac X Zanac
Capcom Classics Collection Reloaded (1942, 1943 Kai, 1943: The Battle of Midway, Gun.Smoke, Vulgus) Capcom Classics Collection Remixed (1941: Counter Attack, Side Arms, Three Wonders, Varth) Cho Aniki Zero Gradius Collection NeoGeo Heroes: Ultimate Shooting Platypus SNK Arcade Classics Vol. 1 (Last Resort)
Soldier Blade Super Star Soldier
I highly recommend Gradius Collection, Zanac x Zanac, Shienryu, Gaiaseed, Sonic Wings, Soldier Blade, Super Star Soldier and both Capcom Compilations and the SNK Arcade Classics.
Dezaemon, NeoGeo Heroes and Platypus aren't too crash hot and can be safely avoided, Sine Mora despite it's lovely presentation is a mediocre and bland STG, Choaniki is an oddity and nothing more, Choaniki Zero is an abomination and Mobile Light Force is perhaps the worst localisation job ever in the history of video games.
R-Type Delta, R-Types & Kyuin were all on PSN at one point but no longer anymore, which is a shame
oh and it should be noted that PS1 games come with a slight amount of input lag, not a big deal really and the average person probably won't notice it at all but it is indeed present and worth mentioning. - --- "Goodbye's too good a word, babe. So I'll just say fare thee well" Bob Dylan
