Well I am looking for some good rom hacks that are complete but I am not fully sure which are good since I haven't played any in awhile but if you can find good complete ones I will give you 1k Viz per find.

pokemon x : So you're just looking for hacks/modifications of games that work, essentially? I know how you feel. A lot of the Pokemon ones rarely get completed to function properly, it seems like. Do you know about the one from a recent RGR Competition, Gold EMU? That hack is actually fully complete and you can really get ALL the Pokemon. TRE, The Team Rocket Edition, is also complete and is fun to try if you haven't done so yet. 

Aside from Pokemon, are you looking for anything specific? If you're at all interested in the Sonic series, Sonic 2 Heroes is quite the entertaining modification that allows you to swap between Sonic, Knuckles, and Tails, just like in Sonic Heroes for the GameCube. It's actually a lot of fun and gives even more replay value to Sonic 2, in my opinion. I think those are really the only functional hacks/mods that I've bothered with, aside from countless other Pokemon attempts. Hope this helps you!

danielbelitch : I will send you 2k Viz and try them out on your first part but on second part I forgot I would like them to be in the GB GBC and GBA games preferred but on the type of rom hacks doesn't matter but like fully complete doesn't matter if there is bugs or not since they all have at least 1 somewhere.

pokemon x : How about Pokemon light platnium or Chaos black?

charmaster : I already have pokemon light platinum forgot to mention that but as far as I can remember about chaos black it stops at mt moon correct?

Pokemon Ash Grey: Idk if there's gonna be another beta, but the current beta I've been playing which is 3.61 is a good 1. It's based on the 1st Season of the anime. Not only does it have the whole 1st season, but it also has Scenes from the 1st movie.

Pokemon Rebirth: !st ever Pokemon hack game I've played on this site.

Rodzilla : Will send you 2k Viz and last I checked about ash grey I think the creator stopped working on it.

What about these?

There's this other 1 called Pokemon Ruby Destiny Reign of Legends which is also good, but a little difficult.
Pokemon Quartz which has fakemon

austipokedude : Out of those pokemon flora sky is the actual only complete one. as far as I am aware but pokemon frosty doesn't really count since it has really basic edits. so sending 1k Viz
Rodzilla : I actually already have both of them yesterday in chat.
