[GEN 2] Can't open save files

[pokemonfan1290]

Hello there ,

 

As a little side-project I've been going through and backing up old save data, but I've noticed that when I go to open my old G/S saves I get an error that PKHEX can't open the file. I haven't had a problem with either Gen 1 or 3 so far.

 

I have attached both save files and the error I get - does anyone know the quick fix?

Try trimming off the 0x30 byte footer.

Could you clarify what you mean by this? I tried trimming off the final 00 entries and then removing the byte in '00' x '00000030' without any luck

Delete the last 0x30 bytes with a hex editor so that the save file is an even 0x8000 bytes long.

Also try loading them in an emulator to see if the data correctly loads there.

I'm unsure if I'm doing the right thing here, would this be the final 0x30 byte? When I delete this I still get the same error as above sadly

When I load the files on emulator it seems to read the battery okay, but there is no save file

After editing it then doesn't seem to load the .sav file at all

[pokemonfan1290]

I have loaded these onto a physical GBA and it looks like the save data on both has been erased, this is why nothing appears on the emulator 

Strange that I'm still seeing data on the .sav files as above, but I guess this solves the mystery.

No


He means 0x30 bytes in length. The entire portion I highlighted. From both saves.


Normally that works, but your saves won't load in PKHeX. I reckon they're just gibberish to begin with. Probably not dumped right.
