1) Is it possible to write 2 games to NOR as long as they constitute less than 32mb? 2) How's the battery life of the SRAM battery compared to the 3in1? I had the latter and I had to constantly change its battery. 3) Do I have to do any soldering to change the battery? 4) Does the EZ Flash IV affect the GBA's battery life as compared to regular retail carts?
