NES MSU1 SRAM Not Found?

Unread post by Magnitudeten »

Trying to play the msu1 nes games, I was able to play Megaman 4 just fine. But Zelda 1,2 and megaman 1 all give me a blue screen as soon as it boots saying that sram isn't found.

Has anyone else run into this?

I had the same problem. The SNES core only supports SRAM up to a size of 128kb, while the default SRAM size in Project Nested is 256kb. Try to convert the ROM from NES to SNES with Project Nested and set SRAM size to 7 for 128kb.

I haven't had any luck with that, I usually just get different errors.

I start with a fresh rom, edit it in project nested and change the sram to 7, save it to a snes rom, then patch it with the msu patch. Tried messing around with both metroid and megaman 1.

The furthest I got was in the case of megaman 1, I got the title screen and I hit start and got a blue screen right away.

No sure what I'm doing wrong.
