I was playing with Boosters Special System Storage and I noticed that there is a flash2 and a flash3, each with about 1MB of space. Im not experienced as a PSP developer, but I had no idea that there were 2 other partitions on the flash. Is there any way to use these partitions? For example: Change where the gameboot is loaded from and put it there to save space on flash0.
I noticed they are blank, so my best guess is that they are used like swap space, which would make them very difficult to use for storage.
