im running pokemon diamond on No$GBA 2.6 and has been working perfectly for me up till now. I saved the game as normal at the entrance to the amity square thing and closed the emulator. Then when i turned it back on im unable to move up and down within the game. I can move left or right but not up or down. Ive tried playing around in the control set up but it didn't fix anything. Any advice with what to do
