Degraded performance on FAT32 SD cards/USB drives that are significantly full

[jmlee337]

the problems can start when the card/drive is about half full
this can cause problems writing replays and even reading from the ISO
this may be a bug in the FatFs library? Not sure where else it could be

did you test on exFAT by chance?

[jmlee337]

exFAT drives do not have this problem. However homebrew channel does not support exFAT so you just have to keep your SD card empty for best results

wondering if _FS_TINY could be related or have other perf impacts
