Hi all,
I couldn't resist and bought a clone console including a "132 in 1" cartridge. After digging around I could not find any information about this on the internet. Either with the name nor with the pcb markings.
I'm not very familiar with NES mappers but searched the Wiki alot. If I'm not mistaken the most PCBs either use some logic chips or an custom chip.
This multi game however uses only a single flash chip (with 2 diodes).
the chip is wired up like this:all other pins of the cartridge are not connected. Including all upper PPU address lines. Even through some unpopulated smd components (or jumpers) could connect cartridge pins 45<->46<->GND (audio), 48 <-> 49 (PPU and CIRAM) and skip both diodes.
Has anybody an idea what to check next?
