The reason for this functionality is that some flashcarts *cough* EZ Flash Omega (DE) *cough* can't be hotswapped IN. When you try this, they will trigger a reset of the gba. This is only relevant for the use case in which you first launch the rom from a flashcart in the first place. I suppose this can only be relevant for flashcarts which offer "single cart mode". (mode B for EZ Flash Omega). So, I added an option to upload the rom to another GBA from the "game_load_error" screen if you press the SELECT button. So, with this change, you could - launch Poke Transporter GB on GBA 1 from a flashcart. - eject the flashcart on GBA 1 - make sure the EZ Flash Omega or other "single cart mode/mode B" capable flashcart is set to this mode. - insert this flashcart into GBA 2 - connect GBA link cable (narrow plug on GBA 1, wide plug on GBA 2) - Power on GBA 2 and press both SELECT and START while the gameboy logo is still shown - On GBA 1, in the "game_load_error" screen, press SELECT - On GBA 1, now press A -> The multiboot upload will now start - Once finished, GBA 2 will now be running Poke Transporter GB as well - GBA 2 will recognize the gen III save! - You can now disconnect the GBA link cable and turn off GBA 1. (you may use it later for the GBC game alongside a GBC link cable to start the actual PKMN transfer)
