Tekken 5: Dark Resurrection & Tekken 6 Possible Widescreen Hack

[LunaMoo]

Probably View or Projection Matrices ~ don't remember as I was messing with it only to work around some bugs affecting in-game camera and long time passed since then, but you might not find values there stored in memory waiting to be changed, you might need to look at Display List where they're set and then follow/trace back the code which is setting them in disassembly.
