This is the PCB published by RBSC, chek out their github site for details:

https://github.com/RBSC/MultiMapperCartridge

Use the JTAG to program the Altera EPM7064 CPLD with 'USB Blaster', the .pof file is attached in this project.

Use a programmer to burn the SST39SF040. 27C040 EEPROM are also compatible with this board.

You can choose between DIL, PLCC or TSOP packages.

Configuration Jumpers:

The cartridge is fitted with 5 configuration jumpers. The block of 4 jumpers is used to select the operating mode

and the standalone PRG jumper controls access to the FlashROM chip. The configuration jumpers can be used as

follows:

* K4 is set, others are not set - Konami4 mapper selected

* K5 is set, others are not set - Konami5 (SCC) mapper selected

* A8 is set, others are not set - ASCII8 mapper selected

* A16 is set, others are not set - ASCII16 mapper selected, default programming mode selected

* No jumpers are set - planar mode is selected (first 64kb of data is visible)

* Any 2 jumpers set - disable the cartridge (booting for reprogramming)

The PRG jumper disables detection of the FlashROM if it's set. It's not possible to write any data into the chip

with the installed PRG jumper. To enable reprogramming of the cartridge the PRG jumper must be removed. By default

this jumper must be installed to prevent a game written into the FlashROM to be erased or replaced.
