    Unhappy famicom hvc-cpu-07 reset problem

    hi guys,
    i've famicom that i've modded for composite av...i run smb 3 and that's run fine...but if i put other games like ninja kun, king kong 2 it doesn't run it show me gray screen and i've made more try like turn off-on various time and some rarest time games run it...of course smb 3 run it without problem...I've see that if turn on smb 3 the reset button doesn't work.
    I've dissoldered and soldered reset buttons but without success...same problem...of course i've see into reset button and show me it's ok...
    i don't understand which is cause...and which item on board can be defect...i think that if i solve reset buttons games can be run correctly...
    I hope that you can be precious support me...i'm sorry for my bad english...i live in italy but i hope that you understand me.
    The board is intact and don't have cut traces...
    thank you in advance
    see you soon
    mike

    It sounds like a cleaning issue for the games that aren't booting, especially since they're working on rare occasion if I'm understanding correctly. No idea on your reset button without being able to see it.

    theres a cap on the NES top loader that will go bad and cause a similar problem to this.

    NES top loaders and Famicom (old red and white ones) are pretty similar. i'd try and change the capacitors on it and see
