There could be a possibility to merge and split save files for Gameboy games. The save file extensions are: SAV - Generic save extension SV2 - NO$GMB Player 2 save extension SA2 - TGB Dual Player 2 save extension SaveRAM - BizHawk save extension Merging save files: Merging two 8 KB saves to make one 16 KB save Merging two 32 KB saves to make one 64 KB save Merging a 8 KB save and 32 KB save to make one 40 KB save Merging saves creates a text file of the games' headers and save types Splitting save files: Splitting a 16 KB save to make two 8 KB saves Splitting a 64 KB save to make two 32 KB saves Splitting a 40 KB save to make an 8 KB save and a 32 KB save For splitting 40 KB saves you have to know what games use what save size. For example, If the Left Gameboy save is from Pokemon Red, it asks you what Gameboy game uses a 32 KB save, you click the Left Gameboy Game button. Another method is by also using a text file that was created by merging saves or by typing it in yourself. Merging saves and splitting 16 KB and 64 KB saves are easy to do, while splitting 40 KB saves requires knowledge.

Well, I can't seem to find any reference on this site for save files being split, so my biggest question is... why?

Like if you have separate save files for Pokemon Red and Pokemon Blue and creating an XML file for 2 players and want to trade, only to find out that the continue option wouldn't show up. But by merging the save files into one, you can see the continue option on both games, you can trade. Now if only we can do the Mystery Gift... that would be for another time.

I did make an SRAM Merging tool. It's not public released though. Would be nice to see how it works in the wild. Splitting the SRAM files, not as easy. For example, Pokemon Red and Gold are not quite the same size. Splitting it, won't be easy at all.
