PSX games that can fit on memory sticks

[PLZKLLME0080]

I have a 512 mb memory stick. what PSX games (for popstation) would be able to fit on it? I would get a 4 gig memory stick, but i need to make enough money for one first. any games that could fit on a 512 mb memory stick would be appreciated. I'm not asking for the files, so dont send me any or post sites that have them. please. thanks to anyone that helps.

Depends on how many games you intend to fit on and what else you have on your MS >.> Most games I've used compress well under 500MB but I find it unlikely that with a CFW you're only gonna have 1 PSX game on it
