I own several game cartridges (and discs) for GB/GBC/GBA/N64/GC/NDS, and I would love to return to playing them on an emulator. For example, I have used MyBoy on Android, and it is an excellent emulator.
My problem is getting the ROM data (which I am licensed to use inside the cartridges/discs that I own), into a file format which emulators can read. And yes, I know the GC discs spin backwards, etc.
I'd rather not use the original hardware since most on the market are well trashed.
If anyone knows of links to such transfer devices or links to forums discussing how to do it, I'd appreciate the help.
