The srm to sav converter gbaconv compiled to WebAssembly. Converts libretro VBA-M and VBA-Next's srm save files and 44vba's 4gs (just a renamed srm) and 4gz (gzipped and encrypted 4gs) save files to sav. It can also convert sav to srm/4gs. gbaconv was originally written by libretro contributors. More info on VBA save formats here.
