Pokémon Sienna (Beta 4) is one of those fan-made GBA hacks that actually feels polished—like someone took the classic Pokémon formula and gave it a fresh coat of paint. You start off in a new region with some familiar faces, but the sprites and maps have this cool, slightly moodier vibe compared to the usual bright and cheerful Pokémon world.

First thing you’ll notice? The starters aren’t your typical trio—I went with this little fire fox thing that evolves into something wild later. Battles feel snappy, and there’s a bunch of Gen 4-5 Pokémon mixed in, which is a nice surprise if you’re used to the old-school GBA roster. The routes twist and turn more than usual, too, so exploration actually feels rewarding.

It’s still a beta, so don’t expect a full 8-gym epic, but what’s here is solid. The music’s got some bangers, and the rival’s way less annoying than some of the official games. If you’ve burned through the mainline titles and want something familiar but different, this one’s worth a playthrough.
