Hey there. I've been waiting a long time for some sort of remake or sequel to Colosseum or XD. If this is the one, and you're planning on adding sprites, Col/XD music and all... I'd be willing to help you. I haven't helped with a game in about 7-8 years. But some of my work is in (notably) Callis Project's Zenforms (an iOS app) and Pokemon Torzach (a project that was never completed). You can view my old photobucket account and its contents here. http://s9.photobucket.com/user/nightpaw/
I have a lot of experience with 3rd and 4th gen graphics, but I promise this can easily translate to 5th gen. I'd be happy to make you some trainer and OW sprites... and I'll send examples of the ones you've requested soon.
I will definitely give this a shot. I can't promise you anything perfect or amazing but I will give it my best. I've recently been improving my pixel art that I've created from scratch so I'm eager to try out what I can do. Do you need animations?
I'm not too good with creating sprites from scratch. I haven't really had the time to practice too much of that. I'm good at recoloring and splicing things together. I could always give it a go, but I can't promise anything miraculous. Is this game like a gen 3 type hack?
I know the 3DS apps can link to DS games, but I'm not sure that 3DS games can link to DS games, besides, PMD3D didn't have enough memory space to have all 648 pokémon in 3D models, so only around 160 Pokémon appear in it.
So I don't think XY will have enough for 800+ Pokémon. Thus some pokemon might not make the cut. So, some Pokémon might not be able to be ported over, causing problems as well.
I kinda hope for Gen III remakes.
But I don't won't Ruby and Sapphire.
I'd rather an Emerald Remake, then either a Blue or a Yellow Remake.
Making it easier to collect Pokémon and a big money maker for Game Freak.
