Yes, only US/NTSC. There is no PAL version for the PSX at least, and not much of us can actually speak Japanese. ;P
.bin (.cue doesn't matter), .img and .iso are all valid... AS LONG AS THEY ARE MODE2/2352. Not all programs will rip the game correctly. Some will not preserve the CD structure. Well I assume you can already play on emulator; if you can, just patch.
