Everdrive gb x3 Fat error
« on: August 14, 2019, 10:01 PM »
Hello, I had already put the same topic on this forum but nobody has managed to solve this problem so I ask again almost a year later.

When I save by pressing the button of the cartridge, it puts me very often Fat error and what forces me to extinguish my gbc and lose my save! Help me, I beg you  :'(

Have you tried deleting the SRAM (SRM games) I had a similar issue and it was resolved in this link http://krikzz.com/forum/index.php?topic=8958.0

 Thank you for the advice, it seems to work, I tell you if there is another problem of save.
By cons, I deleted a file called I think, recentlist01.SRM
But in the backups, all the files were called. SRM, is this normal?

Yes because SRM is different to SAV files. I think at end of the day an everdrive is only as good as what it can contain even if you have a lot of SAV files they may sooner or later need to be removed or reduced to make sure the FAT error wont happen again.

It may be best to see if renaming a folder to keep the SAV and SRM files you want to not delete in a different folder than the default all games are remembered in for further reference, though the sad thing is even if settings are changed the memory feature will always create a back up game you used into that folder... of course for someone like me those over 2000 games remembered was just me checking out to see if they are compatible with the device they are on which I doubt in a normal gamers lifetime would end up in the issue I came across.

My problem was at the time I forgot to keep track of every GB/GBC/GBA and any game the GAB X5 Everdrive could run on... then again I did randomly try and organize what games would only work on GBC as opposed to the standard GB/GBC folder the rom sets are usually defaulted to.

Hmm? What's the difference between SRM and SAV files? From what I remember the Everdrive just saves a raw dump of the SRAM, so there are no special formats. For GBA it may be different because games uses battery-backed SRAM, EEPROM or flash to save. But for Game Boy pretty much every game uses battery-backed SRAM (maybe there are a few exceptions, I don't know).

In my experience the Everdrive does not keep the SRAM dump of games that doesn't have a battery (there is a flag in the rom header for battery that the Everdrive probably checks). I don't know about emulators though.
I have the original EDGB, not the X-series so there might be some differences.

I didn't know the Everdrives has a limit how many save files they can handle, but yes if you for some reason have a ridiculous amount of save files and the Everdrive doesn't work as expected anymore. I guess the solution is to backup all files you want to keep, reformat the SD card and then copy back files to the card again, but not too many save files. Also report the problem to Krikzz.

It's not the save files. It just seems that everdrives like to create a back up of any rom you play which is hard to remember it does that. So lets say you decide to play a Gameboy rom like Mario Land despite it not having a save feature the device will always remember your previous settings. Though from memory there really isn't anything that could be remembered on that game but it will still remember it which is how the FAT error comes to in the end.

I think future everdrives need a way to only be permitted to create a back up of the game if you so much like do it from a menu or save in game. It's not like creating a back up of all the games you play that don't have save states would do you any good... I presume it is vital for emulator games like playing SNES roms on a GBA or even playing NES games on a GBA with the save states and even GB series games which would remember the goomba settings it has but by default why does it need to remember every game you play?
