rescue team

I also remember a few people from /pmdg/ figured out custom starters in DX using cheat engine with yuzu, and one of them was working on a way to make it user friendly.
if you feel ambitious and want to try something yourself, here's a walkthough on how to use the sky editor to make mods for rescue team, explorers, gates, and super. it's limited to custom starters, portraits, models for super, and menu backgrounds
