SNES Cartridge Hirom Sram Upgrade 512Kb Help

[hidden0]

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

The guys himself said Install the 1008 Sram and set it to 256KB it will take care of the issue.
