Yeah, most games use different resolutions. Although the PSX I think stretched the images somewhat sometimes. If you wanna know the resolution that the PSX displayed on a TV...it's 320x240 for NTSC TVs, I believe.
...I think that's the resolution.

The PS1 hardware supports several different modes, the width can be one of: 256, 320, 384, 512 or 640. The height can be 240 or 480(interlaced) for NTSC, PAL supports 256 or 512(interlaced).
Modes with width=256 are very rare in PS1 games, but I know of at least one game that uses it (Dragon Warrior 7). The others are quite common, with 320 being probably the most common (a lot of games use 512 or 640 for their menu screens though).
The way the PS1 GPU works means that games have to draw the entire frame buffer in interlaced modes, so pSX displays these as if they were progressive scan (this is not true for PS2 where apps can request the GPU to only draw the lines for the next field).
EDIT: btw.. if you press TAB and look at the second line you will see what display mode the PS1 is currently using.
