Cave Story Won't Save Sometimes

[rollingharoo]

I got Cave Story running on my F100 but sometimes the game wouldn't save no matter how many times I use the save points. It's really frustrating considering I died at Sacred Grounds and ended up back at the Labyrinth even though I saved at the Prefab House. Has anyone here experienced this problem before?

If it helps, I did reconfigure the GP2X controls in the control text file in the Cave Story folder. Having the A button to jump and X to shoot is way to awkward for my taste.
