* FIFO on arm7 appears to now work as intended. * GBA mode switch funcition remains broken. * Default GBA_Exploader.ini file now created if one is not present. * Moved GBA_File struct to ctrl_tble and removed duplicate from main.c. This was causing issues where I would forget to update both when I removed the now unused Alias char array. All code now shares the single instance which will prevent this issue should this struct need to be updated in the future.
