Hacking m3 real gba saving/loading issue

[Respwner]

Hi, im having some trouble with my m3 real, when im playing gba games everything works perfectly and there are no error messages whatsoever, but when i turn off and back on the save games are gone. Same with the rts function, works if i save and load while playing, but just freezes with a green screen if turned off in between. I can still find the blank savefiles when i connect it to my pc.
Nds games still work, saving and loading included, so does gbc games through lameboy as well. Seems to me like slot 2 loses its information when i turn it off and creates a blank save file when turned back on, or something along those lines.

Has been working like a charm for some time, but suddenly something messed up somehow. Around the time i started using lameboy. Dont know if thats a coincidence or if it has something to do with it.

Would really appreciate it if someone knows whats wrong and/or how to fix this, been searching my ass off without any luck so far.

Your battery is probably dead. Try keeping your slot 2 plugged in as you charge your Ds. That should recharge it.

Is the slot 2 battery charged when ds is off or must it be turned on?
Guess it needs to be on and hope it works

Thanks

Left it charging with the slot 2 inserted through the night (7-8 hours) and still saves blank when i tried it today.
Any trick to it or are its days numbered? :/

My gba games won't save. A save file is made in the GBA folder as usual, but it never loads when I start the game.
Also, when I try using the real time save function and loading the game, the DS freezes with a blank white screen.
I have a theory that it could be because I trimmed the games using tokyotrim, but it doesn't seem likely.
