Everdrive GB X7 - Save state freeze

[sim4000]

Hi there,

I've got a Everdrive GB X7 (for the classoc DMG GameBoy) a few days ago.

Regardless of the used firmware version (I tested 1.02 and 1.04) the in-game save state feature is very unstable.

Sometimes it works (50%), sometime it freezes (after save state restore as well) and one time it resets the game to the start screen.

I use a 16GB MicroSD with FAT32.

Any ideas?

Regards

I wonder if it's a power draw issue? Certainly it sounds like there could be noise on the power line. Does this card put its saves on the SD card, or in some internal flash chip or even some battery backed dram if it's old enough. To rule that out in any case I'd suggest taking the batteries out and using it via a power brick assuming you have one for the DMG.

Good point. I replaced the batteries and now it works (I tested 10 save/restores or so).

I replaced the MicroSD card with a 2GB one as well. No idea if this helps as well.

Thanks!
