The file below, it's you isn't it?
So here's what I did:
1. Renamed your file to .gba
2. Tried to use this tool to extract the save from within.
3. I obtained this
4. Tried to open both in PKHeX. Only save1 opens (the save0 file is a false positive)
So what you probably should do.
1. Keep a save unmodified backup of your file.
2. By the way, I am concerned about the numbers in the filename. Make a few more saves, see if they change.
3. Once you're done editing the save, use HxD, go to the location listed in save1's file name (in this case, it is 0x93010. I cannot guarantee it'll remain constant) and paste overwrite that location.
4. You can now try using that new modified randomnumeral.sav in your emulator.
If it is too complicated, consider switching to a simpler emulator.
