Okay, so the situation is..
We have got some NES, some games, some different kinds of incompatibilities between them, and we can't seem to figure out what NES we have, which game regions we have, and what causes those incompatibilities.

The NES model is the original.

The exact model is NESE-001, and the serial is PE4892009. There is also HOL written on it.

Then we have some games. Here's a table of games and their compatibility.


GameModelRegionBack regionBehavior
Monsters in my PocketNES-1Y-NOEBDASWorks, probably dirty (bad CHR)
Gunman???eur. ver.FRGWorks
Super Mario BrothersNES-SM-FRA?FAH-1Works, sped up
Super Mario BrothersNES-SM-NOE?DASWorks, sped up
SMB + Tetris + World ChampionshipNES-ZZ-NOE?FAH-1Works, sped up
Super Mario Brothers + Duck HuntNES-MH-FRA?FAHResets itself (10NES?)
Mission: ImpossibleNES-V4-FRA/FRABFAH-1Resets itself (10NES?)
Soccer???FRAHOLResets itself (10NES?)


The confusing thing is, see, the NES model is presumably PAL. But we've got European carts that work perfectly, European carts that are sped up, and European carts that seem locked out. Does anybody know what could help explain this behavior? Are we missing something really obvious here? Just plain googling didn't give us any answers.

Thanks for any help!

Has it been modified in any way?

I know that when I was young the local videogames rag used to have advertisements for 'Turbo-charging your NES or SNES! Make games 17% faster!' which now that I'm older and understand tech a bit more meant that they were doing some NTSC-based mod for the console that'd run them at NTSC speeds instead of PAL speeds. So perhaps you've got a badly hacked NES!

All the games are PAL B. The lockout is simply due to a poor connection, same as the weird graphics.

Super Mario Bros. is one of the handful of games specifically adapted to run at the correct speed on PAL consoles; most games just run slower. Are you sure the games that "work perfectly" aren't also running too fast?

You can easily open the console and check for mods. It should be fairly obvious if anyone has been tampering with it. If you have any doubts, post some pictures. (Maybe post some pictures anyway; it might be interesting to see.)

You will find Bootgod's NES cart DB useful; here's SMB [NES-SM-NOE].


Interestingly, your SMB+DH cart [NES-MH-FRA] isn't in the list! You should submit it if you can.

The reason we claim SMB runs faster is because the music is obviously sped up, and the demo flails and kills itself shortly. Unless that's actually normal and Nintendo just released a broken PAL port. Which would make me even more confused...

I'll look into the other stuff. But we checked the contacts and they seemed clean...

I've just checked, and the PAL version does indeed have faster music and a failure of a demo. Actual gameplay should be pretty similar.

I'm not sure what to tell you about the cartridge connector; I just ended up buying a replacement for a particularly bad console. (It works so well, the cartridges don't have to be pushed down!)
