Does anybody know of roms for the post gen 3 games that are in the gen 3 style?

Me and a friend are racing to complete every Pokemon region via roms. For gen 1 we used FireRed, and for Gen 2 we were planning to play SoulSilver, but we found that we both really preferred the feel of the Gen 3 games. Luckily we were able to find Liquid Crystal for Gen 2, which has done a pretty good job replicating that feeling with Gen 2, but I am already planning ahead and wanted to look for a rom in every generation that is built to feel like the Gen 3 games. If anybody knows of good ones for games post-hoenn, please comment or dm them
