Famiclone Cartridge not working help!!

[TheRetroLifestyle]

Hey guys,

I have a repro Famicom cartridge that is from the 90's. I took it from an old 90's Famiclone. When I insert it, I could only hear one game ( Street Fighter clone soundtrack eventhough the Cart is a multicart that has many games ) Other times, I hear nothing, only black screen. In some cases, I see the usual multicarts menu that has a list of games but not clear ( a messed up pic ). Anyway, the interesting thing is when I insert the cart, the first two-three seconds, one Eprom gets soooo HOT unlike the other Eproms. I will attach the cart board. I need help please to make it work!


Thanks

Interesting, among so many cartridges I have reverse engineered so far:

I never spotted something like yours (4 PAL CHIPS, AX5904=MMC1, BLOB 40 = MMC1).
Looks like it is some kind of MMC1 + subset of MMC3 + NROM multicart.
If some of the EPROMs gets hot, it is definitely broken.

Why did you mark 16L8 chip in red circle? It is not an EPROM but programmable logic chip.

To fix the cartridge, first I need to restore the schematic, then find out how the memory mapping works, then probably reading the eproms could be neccesary, reading and analyzing all the 16L8 chips, and finally - find out which of the chips are broken and fix them by replacing by good one.
If EPROM/16L8 chip is broken, it needs to be first pre-programmed with proper content.

Unfortunately many of the tasks need special equipment which probably you don't have (PAL chip analyzer, cartridge dumper). Plus many hours of work.
If you want the cartridge to be fixed, you probably need to send it to me, though by the uniqueness of it, I think it is worth it. Because I do it as hobbyist and for sake of updating the cartridge database, I would not charge you for anything but the shipping costs (5$).
