Playing on MAME is the better option, because you get the correct translation (if you play the World ROM), and you don't deal with the f*ckery of those twerps mucking up the game.
The DC port of Gunbird 2 is lovely AND correct AND has Morrigan and Aine (great characters), but nowadays very expensive (not if you have blank cds though lol).
On the PS1, the port of Strikers 1945 II (confusingly named in the West as just Strikers 1945) is pretty good, and should still be within cheapish range... though nothing beats buying it new for $9 a few years ago...
