I posted this question in the GBA flashing and hardware section but didn't get any answers. Hopefully someone here can reply. I mainly want an opinion so I can get the RMA process started if that's what is necessary. I recently ordered a CycloDS Evolution and an EZ 3 in 1 expansion pack from RealHotStuff. Items received, everything seems to be working fine and I start the arduous process of backing up my DS games using the NDS Backup Tool 3in1 v0.31 : http://gbatemp.net/index.php?download=2775 It seemed faster and more reliable than the wifi method (which gave me trouble and produced a bad ROM). Anyway, things worked fine for a while, but on the latest backup, it starts to erase the NOR memory as normal, but then it gets to 30% and sticks there. I let it go for 30 minutes with no progress. Repeated attempts showed the same behavior. I downloaded the gba exploader tool and one of the larger homebrew games (super mario, last gba quest) to see if I could maybe "unstick" it using that. It started to erase the NOR memory and stopped just like before only at 77% this time (which makes sense I suppose since it doesn't take up all the memory). I tried running the game in SRAM and that worked ok, but the NOR memory still doesn't work. Does anyone know of anything else I can try? Or is my NOR memory bad and I should get it exchanged? Sorry if this has been covered somewhere before, I did a search but didn't see anything similar.
