Broken Super Mario All Stars + Super Mario World snes

The game plays mario 1, 2, lost levels, fine but mario 3 is all glitchy
and super mario world doesn't play at all. The game has been cleaned
and still has these two problems. Does anyone know how to fix this. Has anyone ever had this happen to them with snes games?

  • have you opened up the cart? Maybe you can open it and take a picture for us.
  • clean it with weimans!

    The contacts have already been cleaned, and there's no corrosion on them. 
  • hmm...I was really expecting to see something unsual. As far as I can tell from that photo though everything checks out, no loose connections, no breaks, everything looks clean. Maybe someone else will see something I'm not though.



    This might be a stupid question but have you tried playing it on another machine to see if it makes any difference?

    I will try the game in another system tonight.
    Thanks for your input everyone image
  • I'll be interested to know what the outcome of the other machine is. As was stated above, there's nothing obvious that is wrong with the board, chips, etc...
  • when you say mario 3 is glitchy, do you just mean the graphics are glitchy?

    If so it could be the graphical data portion of a chip is starting to corrupt
  • Tomorrow i will tell you the outcome, need to find my other snes system first image

    I will also post game play pictures of mario 3 too.

    I had the impression that one-time-programmable chips were not susceptible to bit rot, unlike EPROMs.
  • OTP (one time programmable) chips are susceptible to bit rot like normal UV EPROMs. That's beside the point here, because this and almost all other SNES carts use mask ROMs, not programmable chips. image

    I guess the fault could lie with any of the chips really. Maybe the SRAM is bad (if the game uses part of that for anything other than just save data), or the MAD-1 address decoder chip???
  • Seems like semantics to me, but is the mask ROM not a "chip" that has a "program" written to it, hence making it a "programmable chip" image
  • Hmmm, I have a problem with Crono Trigger where if I go to the menu the game somehow freezes but the BGM is still playing. Is that a cause of the games battery or the SNES?
  • I have a super metroid with a broken leg on the battery, it plays up until the first save spot and freezes. Possibly similar to the Crono Trigger problem. As for this game, this is an outside guess, but maybe when the case was open you static shocked one of the chips? I've never really heard of anyone killing a game that way, but under the perfect conditions I imagine it is possible.
  • Sorry for the delay. Tried the game on another snes system, nothing changed. The game saves fine but mario 3 looks like crap but fully playable. I took some pictures of mario 3's gameplay.
