Thanks for this great tool. I like to suggest the addition of the following feature:
Please add a GB/GBC mode, so that it is possible to inject ROMs of these consoles, changed with the goombacolor emulator and by the process of zero padding (these made by the user with other tools to turn GB/GBC ROMs into GBA ROMs with 16 MB).
I know that a tool like "GB/GBC injection injectiine" already does great part of this processes, but, recently, I have not been successful in using it.
I believe that this insertion will not be very laborious, since the injection process will remain the same for GBA, and the "conversion" of the ROM will be done by the user. The significant change to this mode would be the addition of the GBC VC icon and banner templates, which I attach here (I forgot who is the original author of the templates :/).
Could you consider this addition?
