I just used it but i dont see any difference at all. It even said RAM recognized.DanTheManMS said:It's automatically used, but check the snemul.cfg file in a text editor to be sure exactly how it's being used.
Basically it's only used for storing the rom image so that the paging system doesn't need to be used. It has no effect for smaller games, only ones too large to fit entirely into the DS's RAM at once.
You're right, I forgot this detailsDanTheManMS said:The limit is actually somewhere around 3 MB, as the emulator itself has to fit into RAM as well. In fact, I don't think it even works with those very few SNES games that are over 4 MB in size.
