Are you sure they're stolen? I do believe Flora Sky is a bad ROM Hack that doesn't deserve hack of the year but I like to play it. Somehow... Even weirder I like playing the Complement Dex version more even though people use legendaries. *insert even Jackie Chan is confused picture*
Sorry for the whole Sarcastic Prince thing, calling someone a Sarcastic Prince or Sarcastic Princess is a really bad idea. Also Ditto just invaded your account! I think. Or was it Kirby? Hmmm.... *shifty I I*
I don't think editing a Pokemon game's tileset is important at all. After all Pokemon Azure Horizons and Pokemon rijonAdventures have minor tileset changes and both of them became Hack of the Year. Same thing with Sienna and it has some Fire Red tiles mixed in.
Well either way the graphics of a ROM Hack don't matter, it's what's in the ROM Hack that's more important. Also I am aware that WAH ROM Hacks use ASM, like uhh... Light Platinum, Quartz, Marble, not sure Shiny Gold has but probably.
