after you format with the panasonic formatter, if you check it in your o/s, it reports as having enough free space? both of those games work just fine for me. i tested them in 3 acekards and 5 different msd cards using 1.6 rc2. your msd card is probably starting to go.
try untrimmed clean roms.
make sure you have at least 100 mb free to save file creation.
don't use the same save files created with any trimmed roms.

I just did a full format (instead of a quick one) using the Panasonic formatter. I then copied only the AKAIO RC2 and Sonic rom to the microSD card, and it ran fine. I looked at the save file it made (now that it was finally able to get far enough to make one) and it was 512 kb. Considering I had around 7 mb free before, I don't think that was the issue.
Post full format, all roms loaded, with sav made just now: Loads, but I was unable to copy back over one of the gba roms I had on there before. Teracopy said the file or folder could not be created at the target. 25 MB free.
Post full format, all roms loaded, without sav (the way it was before): Loads.
I've been testing out transferring files to it, and now it seems that I'm unable to put anything "new" on the microSD card. If it was on there before, it will transfer just fine, but even a small file can't be copied.
Ok, I think this is actually a limitation of the FAT filesystem, or maybe the microSD card itself. Once you reach a certain fill percentage of the storage medium, it doesn't even let you write files to it anymore. This is what was causing the problem before. It had enough space, but the filesystem wouldn't allow it.
Anyway, count this as resolved, I suppose. Thanks for the help, guys. Now I just have to delete a few roms off here...
