I know that PAL is not alowed but I found some difference between PAL and JAP version(not 50hz/60hz). I think that can change game-time and game-experience.

After Spawn:

• PAL 7 enemies in first street
• JAP 5 enemies After the bus, there are more enemies in the PAL. -> It's hard to get the special key from Brad.

The Room where you are using the 2 red dia (Leon A):

• JAP there is no animation when u pick up the shotgun ammo
• PAL the character knees down to pick up the shotgun ammo

Is there any difference in RE1 & RE3? (not 50hz/60hz) (Sry 4 my bad english)
