Some of my `fixes` are really crazy (probably no one would even want to waste time for that), for example:
* Fixing broken (blob) CHR-ROM memory:
* Fixing broken (blob) mapper chip (MMC1):
* Fixing broken (blob) CHR-RAM:
* Fixing broken PAL chip -> replacing with Xilinx CPLD (version 1)
* Same but with Altera CPLD:
* This one consisted of 2x 8 MBit memory, which had single data bus pins broken -> instead of replacing them, I just installed one memory that fixed data for the broken pins:
* Broken ASIC BF9096 in Codemaster cart -> fix with CPLD:
* MMC3 chip had broken IRQ line -> I had to implement this on cpld:
*JY-120 (45 in 1): Some upper PRG/CHR lines of glob-mapper were broken but also reading PRG-ROM returns non consistent results
*Wario Land: CHR-ROM was broken, but instead of soldering 32 wires, soldered add-on board:
*Dragon Ball: Mapper chip was broken, but I was curious how to read PRG/CHR roms, so I soldered add-on board with latch:
