SNES Cartridge Hirom Sram Upgrade 512Kb Help
Posted: Wed Apr 19, 2023 6:29 pm
Hi guys again ,
So this time i want to Upgrade the Sram of a Hirom board to 512 KB since none exists , Why ?
Because there is this BS Zelda Third Quest / Fourth Quest Roms require 512Kb of sram , i tried running them on 256Kb with the Flashcart it didn't work.
There is an Extra A15 on the 512KB which i think needs to go somewhere on the cartridge pcb.
Saw that turotial worked well but it is upto 256kb

Willing to use any 1J3M boards , Also i have mousebite labs Advance Snes cartridge PCBs , Which can take 1008 Sram which is a 1Mb of sram , But there is no option on the board supply the rom 1MB.
Any help would be appreciated
