As you know already NES Mask ROMs pinout differ from standard EPROMs so you need to find out the Mask ROM pinout
You can use
Mask ROM pinout to find out the pinout of the Mask ROMs to some extent
But for a complete pinout you need do some real work :
MMC5 pinoutCartridge connector PinoutLaser Invasion PCB ImageRemove the Mask ROMs from the Laser Invasion PCB
By using a multimeter, Cartridge connector and MMC5 pinout try to find out the Mask ROMs pinout as well as the Laser Invasion PCB hole pinout
Go to alldatasheet.com and search for the datasheet of your favorite EPROMs and find out its pinout
Compare the pinouts of your desired EPROMs with the pinout of the Laser Invasion PCB so that you will know what pin connects to what hole
By the way I want to see the picture of the destroyed cartridge, And don't get the wrong idea
I don't care weather you are a repro maker or not, I just enjoy seeing FC and NES stuff
Also it would be great if you post your finished work and Laser Invasion PCB hole pinout as a reference for future works
