Unless something goes horribly wrong, I'll have 10 GP modded CHA-01s up for sale ($10 each) by the end of next week, just waiting for some stuff to come in; check my post in the marketplace for some more details
I'll also give my own shot at coding a rudimentary text editor and seeing where that leads me; I've done it for my graphing calculator (A casio cfx-9850gb+, IIRC; in bed right now), so I could probably figure it out for the gp32 after some practice. If I get that working, I'll be selling the keyboard + a 32 meg card with my own (Much better than just rudimentary if it'd be for sale) text/hex/rtf editing program for around $25
