i hope this is the right place to post this? but i have created my first repro (earthbound zero) using some online tutorials but i only get a white screen when i put it in my nes and yes i have tryed multiple nes systems all the same result. i have used a copy of deja vu for the nes as donor cart and removed the old chips using a de-soldering iron they came of very clean. then i programmed the eeproms (27C010) as PRG and CHR and soldered the wires to the clean board then the eeproms and after that the wires to the eeproms. i mostly used callenbrown.com with his advanced MMC3 repro guide and i also used this table for the wiring TKROM & TSROM (mapper 4): PRG socket: Bend up pins 1, 2, 24, 30 and 31 (or cut tracks 2, 24, 30 and 31) Solder pin 2 to hole 24 (A16) Solder pin 24 to GND (OE) Solder pin 30 to hole 1 (A17) Solder pin 31 to hole 2 (A18) CHR socket: Bend up pins 1, 2, 22, 24, 30, 31 (or cut tracks 2, 22, 24 and 30) Solder pin 2 to hole 24 (A16) Solder pin 22 to hole 31 (CE or CHR /A13) Solder pin 24 to hole 2 (OE or CHR /RD) Solder pin 30 to hole 1 (A17) here is the picture of the completed repro i wanted to clean it up but i thought i test it first before cleaning it up i,am using kynar wire to connect everything. any help would be appreciated!!!
