Hi everyone,
I am currently working on an SNES cartridge that will be able to load and run games from an inserted SD Card. With a working breadboard prototype (which is currently limited to a single 16 Mbit LoROM/HiROM SlowROM with .SRM autosave to SD and also a complete mess), I am now pondering how much RAM the final PCB should have.
Actually, I'm trying to decide between 48 and 64 Mbits.
I was planning to use 48 Mbits of SRAM (+1Mbit work RAM / save RAM) because AFAIK the largest official SNES games sold have 48 Mbits of ROM. Are there any modifications (e.g., translation patches) that expand ROM size beyond 48 Mbits? I think I heard about some 64 Mbit patch but I cannot remember...
I'm not counting the 96 Mbit S-DD1-less version of Star Ocean because I plan to (eventually) support S-DD1 through the FPGA.
Any hints are highly appreciated.
