SNES Rom region switching
« on: February 23, 2013, 04:00:48 pm »
Is it possible to region change a SNES rom from PAL to NTSC? it isn't protection related, but more to do with the only emulator that my console uses doesn't handle PAL games properly, it plays them too fast whilst NTSC games play normal speed.

There isn't a (U) dump of the game in question. Only a (E) version.

Any help would be appreciated.

be sure to read through the whole thread as there seemed to be some confusion in the first 2-3 post but
the problem was resolved using this method according to the OP

I wonder what game is it.

Anyway snestools can do something as well if my memory isn't wrong.
Anyway there is an internal header in the SNES roms and there is a region definition there, change just that byte could maybe fix your problem.

It's pretty unlikely that just changing a couple bytes in the header is going to make your PAL ROM run correctly at 60hz.

Fixing that would require good ASM knowledge.

Here's a list of all the games I recognize from GameFAQs database to get a EU release but not US.
If I'm missing any, it's probably just more soccer games (or name variations of the many soccer games on this list). :P
I imagine only a relative few are probably worth playing. :)

The Asterix games have a pretty good soundtrack IIRC.

And yeah, it's highly unlikely that a PAL game is easily converted to NTSC by changing a few bytes in the header. If it were so easy we wouldn't have had to play almost every game slower than intended and with black bars on the top and bottom.
