Feature / ApiHawk tool request: SaveRAM importer/exporter for other emulators

Here's a list of all the formats that have been requested to date. --yoshi

Also #3142 for NDS.

Original request follows.

Could anyone add a way to read or to convert Sega CD .brm files from other emulators into the format Bizhawk uses?

.brm sizes are 8KB, 16KB, 32KB, and 64KB, but Bizhawk's SaveRAM is 24KB and I haven't found a way to be able to convert it, or to even reduce the KB size to see if that way it would "match" with the .brm sizes. Renaming them like how I could do with Saturn or Playstation save files doesn't work here.

So hopefully someone is able to add this option in the future.

Thanks!

Start by locating BizHawk's existing SaveRAM import/export entry point and compare its format handling with the .brm sizes and the .gme rule described here. Done means the requested emulator save formats can be read or converted, with related context reviewed in #3122 and #3142.
