As this is a GB game, can GB, GBP, and SGB2 be added as valid platforms? GBC as the only one doesn't make a lot of sense.

Hey o/ Do you know if GB GBP and SGB2 can share te same leaderboard with GBC ? (I mean can the times be compared)

I played through the GB version some times and from a high-level perspective they seem pretty much the same. Thanks @itsme_baruch for adding the other platforms (and the new category)!

There are some differences regarding the password system though:

Only one password: DJLRR (Dalton, Jolly Jumper, Lucky Luke, Rantanplan, Rantanplan) for the Buffalo level.

For the GameBoy Color, there are passwords for all levels:

• Stagecoach: RDJLJ
• Painful Gulch: RRDDL
• Saloon: JDJDR
• Train: LJJDL
• Prairie: DLLRJ
• Buffalo: RJLDD
• Ranch: LJRDR
• Rapids: JJLRD
• Cheyenne Mountains: DRLJR
• Jail: RJLDR

If anybody notices some more differences please let me know!
