PokeGen can't edit my pokemon in a White Sav

[Eddiescouch]

I've been trying out PokeGen for a few days now, but I've repeatedly had the problem where it can't edit any of the data in my actual pokemon. Now, everything else functions as it should to my knowledge (for example I can create new pokemon and change the arrangement of my boxes) and it can read the data from my save just fine. I don't get any instances of weird data popping up either.

Where I get my problem is here:
I'll go in to edit a pre-existing pokemon, change all the things I need to, save the edits over the previous sav file, but when I go and re-open the sav in PokeGen, or go to play the game, none of the changes took place. I've tried it where I save the individual pokemon with the changes, closed the sav file, opened it again, and then open the .pkm file to set the un-edited pokemon as the edited version. Those changes don't stick either. I've tried both with 'Ignore checksum' checked and unchecked; it doesn't seem to make a difference.

For the record, I'm using an R4 ROM and it is saving as 4 MB. Just to be through, the ROM is White in Japanese.

Did you "set" (Right-Click "Set")the pokemon, if you didn't there's your problem.

[Eddiescouch]

yes I did, for each pokemon, and then I saved the file after each time. It still wouldn't take when I re-opened the file.

For one thing the save should be 512 KB not 4 MB, so try changing the save format.

He probably meant 4MB as in "4 Megabits."
Though it should have been 4Mb and not 4MB, we might need confirmation from OP.

4Mb=512MB
Even if the OP meant 4MB, that still won't hurt. The save file can be larger (unless the flashcart doesn't support it), but not smaller.

@vergil2010:
1. Load Save
2. Right Click > View Data
3. Make changes
4. Right Click > Set
5. Save
