Hi to all. Assuming my EZ Flash 3 in 1 arrives. I have set Rudolph's GBA Exploader and the 3in1 Expansion Pack tool on my flashcart. I notice that the GBA roms can run automatically without opening the gba exploader. Is this normal? Can I just open the rom itself rather than opening the exploader first? What's the expansion tool for in details. I cant understand the readme that came with it. Thank you for your time. All my GBA roms are 16MB like pokemon GBAs.
