I'm not sure how else to describe it. I tried loading in whatever was in the Battery folder that apparently houses save files.

I literally just tried accessing my save by loading that instead of the main game (because when I loaded the game my save was gone). And as said I am not at all tech savvy. If I have to have all this technical knowledge just to play a save file in a game then I'm getting a different emulator, like I don't know how else to describe that besides that it's fucked. In literally every other emulator I have I'm able to access my saves with no issue. I know save states are a whole different thing and I've read that from this is where most issues arise but as I said this was the in game save, not a save state. Ranting aside, can you tell me why this didn't work and how I can avoid this issue of not being able to load a save in the future?

Just redownloaded Desmume, and put the extracted stuff in a folder I made. I'll try the game itself out at some later date, since I've started on a different game and the intro (meaning getting to a point where I can save) to Pokemon Black/White takes longer compared to the other games. But I wanted to clarify that initially I was running Desmume from the extracted folder and it was letting me save in game. But to avoid this in the future how would I access my saves in a useable format?

How can I tell if my stuff is an archive? I only remember seeing/using zip files.

I don't think I can upload pictures here but I do have an app shortcut thing for Desmume. I may have just moved it out of that zipfile though. And I'm super confused about the "downloading everything again" part, from where would I do that? Do I need to go to the Desmume site and download the emulator again and basically do the same for Pokemon Blaze Black, or can I do it from a folder?

By "download everything" what exactly would that be? Would it be the game, emulator, or both? Also wanted to clarify I didn't make any new files, they kinda just appeared on their own. As for the dearchiving part I didn't do any of that unless the emulator did it by itself, as I don't know how to do that and I only have a vague idea of what it even means.
