I thought to post my question here as well, other than in the CRT thread.
I play my PlayStation games on a fat PS2 + Trinitron CRT TV (not that intensively anymore, hence why I literally just noticed this issue), with both speed and texture set to standard. Is it normal that some titles show what it looks like jail bars - especially on grey or not-so-bright textures/colors - and others don't?
Examples. Every single 2D game I've tried so far, looks fine (i.e. Guitly Gear, Gunners Heaven, Angel Eyes...), as well a some 3D game such as Dead or Alive and Toshinden 2. By 'fine', I mean they look exactly like I remember them looking on a genuine PlayStation, crisp and clean.
Then, on the other hand, there are Tekken 3, Chase the Express and Gran Turismo 2 (once again, out of those I tested), which show prominent jail bars, both on actual textures and 2D backdrops. It's not random, they're always there, in the same spots, with the same games. Are they meant to look like that? Does it have anything to do with their screen resolution?
I use a PS2 Sony RGB cable, and unfortunately it's ages I don't own a PlayStation anymore, so I'm not able to double check on that system.
