StarsMmd, you are a genius. Your work on XG, modding to that extent one of the lesser known Pokémon games, with no romhacking scene to help you, is awe-inducing.
The Gamecube games are criminally underrated, yet the Pokémon there look better than any mainline series ever, and the world is so much more interesting.
I am curious about what can be done at the moment in this romhack.
-Orre is supposed to be a land so lacking in Pokémon, that the majority of them are imported and sold. Could you turn shops into Pokémon shops where you can buy Pokémon, similar to the Celadon Game Corner?
-Is it possible to import move animations from Colosseum to XD? Not only Colosseum's moves are less cutesy-sparkly and more intense (compare Shadow Rush, Flamethrower, Shadow Ball, Psychic, etc), but it would also increase your total number of available animations (for example, have Flamethrower use the Colosseum animation and use the XD animation for, say, Lava Plume)
-Would it be reasonable to mod in a barebones breeding system? As in, say, you can put two 'mons in the daycare, and once you exit and re-enter there is a chance to get an already hatched baby.
-In that same line of thought, can the PC be expanded to have more available boxes?
Aside from that, I would love to know if you have considered those two things:
-Releasing a Windows version of the Editors for Colosseum and XD, to kickstart the romhacking scene for these two games and ultimately drawing attention to your own.
-Creating or joining the Pokémon disassembly discord server; I'm sure they would be delighted to add a section for disassembling the Gamecube games, and their help would be very useful.
Anyway, best of luck. I'm sure the best is yet to come.
