My DSi system is currently on 1.4.4, and I seek to downgrade it someday so as to be more open to flashcarts(preferably without hardmodding a hole in the back for connecting to a Raspberry Pi system via wire-connected Micro SD adaptor). I have already used the Action Replay device on my older DS lite with good results. The Device is currently at FW 1.14 right now. I feel I should update it someday via USB and the mini-DVD esque disc that came with it put in a connected external optical disc drive drive to my Dell Laptop. What FW should I update My AR DSi to in order for it to work on post 1.2 Dsi Firmware? Or should I downgrade first , then do the Action replay stuff?
