sangmin · Feb 19, 2020

Hello.

Is it possible to transfer save files EZ junior <-> PC emul?
Recently, I lost my DQM1 save file. So i want to back up my save files to PC

1. OK with save files PC emul(VBA-M)
2. NOT working save files(from PC emul) in EZ junior

Is there any solution?

thanx

Backing up your saves does not require an emulator they just .sav files so back them up to a folder on your pc

are the save files the same size?

i think vba-m might accept different size game saves, and the ez-flash jr might not.
(some emulators or flashcarts make the saves larger that needed)
there might be a setter in vba-m, to choose the save size? so, when you save, the save is compatable with ez jr.

if vba-m still gives you problems, try using mgb, it's a different, more modern emulator. maybe it will help.

1. I backup my files.
2. I play with it using pc emulator
3. I transfer save file to Junior.
4. The Jr can read files made from pc emulator

That's my problem.

The save size is same "8kb"
I tried several emulator. They are not OK.

very strange...
what I would do:
get a game (maybe DQM1) in your emulator, and also in the ez flash jr.

start a new game in both and save.
ideally, the 2 saves (1 on pc, 1 on gb) will be identical.
upload both files here, and I will see if there is any difference. (i will use a hex editor on my computer)

2 files, but one is the game...! (be careful, we cannot share rom files here)
i want 1 save from jr, and 1 save from your emulator.

I just find out what is the problem!!!

It is "AUTO SAVE"
unchek "AUTO SAVE", I can load saves from pc emul.
I think when you turn off GBC, ezflash J get save file.
then when you turn on, It is actually saved.
