Well... I started to take a look.
The game uses 2 blocks for saving data.
It seems that one is for user name, maybe score and the other is for level edit data.
original adresses are 0x0FA000 (user name, maybe score or unlocked levels)
and 0x0F8000 for custom level data.
I think I've found all erase/write functions, I still have to find the data loading functions to create a fix.
ps : Saving custom level don't seems to work in neopop.
