Hacking GBA VC games not keep saves??

[Keylogger]

Hello,

I have a problem with my GBA VC games that aren't always saving... ?!
I have a N3DS with A9LH autoboot to Luma3DS Sysnand 10.7 with my GBA VC games on Sysnand.
I played Pokemon ruby, I saved then turned off the 3DS. I powered it ON today, launch pokemon ruby but my save isn't here! I have my old save and lost 2 hours of gameplay...

Same thing happened with mother 3 too but sometimes it saves, sometimes it doesn't I don't know why..

Can you help me?

Now that's pretty weird, your setup sounds correct, Ruby uses a 64 kB save which is correctly emulated by GBA mode... if you converted it yourself, is the save type selection correct (Flash)?
