8bit Music Power Cart (internals)

[byemu]

It's normal mmc3 (mapper4) cartridge.

That is interesting. Maybe the problem is how I am dumping my cart? I used kazzo/infiniteneslives pcb and anago_wx and tried mmc3 and mmc3_v2 and the rom will not dump correctly, or run. The mapper must be set to 118 to boot in either powerpak flash cart or fceux (or nestopia). It will not work set as mapper 4. Even with 118, it has graphic glitches then:



How are you are dumping your cartridge? I can assume not with a kazzo unit.

Kazzo can not dump chr(prg is ok), I dont know why.
The right rom info is 512K PRG( CRC:e895b68e) 256K CHR (CRC:9848f8bc)

You can dump this cart with TapeDump.
Direct read ic with a programmer is also OK.

Thank you very much for clearing up this mystery, I may try tapedump to get a correct dump for personal use.

Apologies if I have threadjacked here at all too.

Just wanted to pop in and leave a thank you to genepensive for digging up how to repair the cart. Got my cart up and running this afternoon!

EDIT: 8+ hours at 300bps later, I can confirm that it dumps correctly with Tape Dump's MMC3 settings.

Digging up this topic again. Just recently bought 8 Bit Music Power Final (the newer version) but I still can't dump it.
If anyone has it and would be willing to give me their dump I can give proof that I own the cart.
It works fine inside the Famicom but I'd like to have it on my PC as well.
