I've got a problem with NES hacking

Actually, there are you versions: PRG0 and PRG1. Didn't look at the codes of both to say if the GG will be affected by version issues.

cyperium your codes do not work
as for your version argument there is only 1 version of super mario bros 1

It does work on my "real" Nintendo, but it doesn't work on my emulator, so I guess I have the same PRG version as you do (and the other people) on rom, but at home I have the other one.

So which version doesn't it work on? Would be nice to know which version is which.

Also, my Super Mario Bros. at home is scandinavian (at the back of the cart is the SCN abbreviation), could that have something to do with it?

**EDIT**:
I've found two Super Mario Bros. roms called REV0 and REVA, the codes work on REV0. I guess it has to be the European version, as it seems only the (u) version has PRG0 and PRG1 while the European version has REV0 and REVA (where REVA is updated graphics which looks like "lost levels" version of SMB2, it's most likely a hack of REV0)

The codes will work on REV0 (european version).

ahh so you have the european version please be carefull when posting codes to enclude which version you are using

Remember, GG will not work on different versions and regions.

Can you add the codes here? They aren't that bad (they are also for the european version)
