M3 Lite save function

Hi,I hope you can help me. I am not good with computers so please bear with me. I have had no success looking up trouble-shooting issues online.I just got my M3 Lite and there was no disc included; is there supposed to be one?I downloaded game manager v. 36 using the FAT format, but I cannot save on more than one game. I think it’s because I’m not using the game manager properly and the save file that’s created or the .dat file is not being converted onto my M3.After I play a game, turn off my DS and start it back up I get this message;Warning! GBA gamesave already exists on this card, but ‘GAMESAVE’ directory cannot be found. Backup failed. Press a to continue. I have a GAMESAVE folder in my game manager and I put the game manager on my sd card. Am I supposed to keep the game manger on my PC?Also, when I press a for fast open on a game I get this message;Warning! Card has not been formatted. Please shut down and insert a Formatted Secure Digital Card. Or press START to continue anyway.Please tell me step by step what to do, and I mean STEP BY STEP because you’ll have to dumb it down for me.Any help is very much appreciated. Thanks!

first thing to do is to reinstall the firmware using the latest one from www.linfoxdomain.com/nintendo/ds, and following the tutorial in our tutorials section.

Thanks for the link, but isn't v.36 the latest? that's the highest number I see there and thats the game manager I have now.Also I went to the tutorial section and didn't see anything under M3 Lite, sorry to be difficult, more help would be awesome!

the tutorial isn't specifically for the M3, its a generic one that works on all.

i looked under all the tutorials and found nothing generic that applies.... Which tutorial is it specifically, are there archived tutorials that don't show on the tutorial page?

Use this tutorial which applies about to all flashcarts. https://www.romulation.org/forum/index.php/topic,816.0.html
