Has anyone considered adding Beta Pokemon to a ROM hack/Fan Game?

I personally don't know of any ROMS or fan games that have made that attempt to add in some of the beta pokemon that we are now aware of. I understand that all we really have are some sprites and some minimal information on some of them, but I just feel like it would be something interesting to play around with?

Also if there are ROMS or any fan games that are working to add in any sort of beta pokemon, I would love to know about it!

There are gold and silver 97 reforged, they also add other things from the beta like unused maps.

Ohh! I'll give it a look then, thank you!

Building on this question, has anyone found/made/seen the Beta sprites in HG/SS style? I usually find one or two, I've yet to find a complete collection.

Pokemon Electrum 2 has some. I didn't really care for the game myself and stopped playing before the 1st gym, but not many hacks hold my attention so it could be a solid enough game.

The only game with beta is Gold 97. Someone can still make a Blue version (beta) on GB tho.

The hack in my sig has included most of them.
