Here's Hedgehog Abuse Simulator, an experimental hack. You play as normal, but can switch to debug mode to place different types of spikes. The idea is that you use them to solve puzzles and advance.

Bumping with the Fully Playable Zero Hack for Megaman X3. As the name says, you can play with Zero through all the game (excluding the introduction stage). It even has new animations and sprites.

Holy shit, this is great
Are there any other great Megaman ROMhacks?

Anyone know which hack carl.ips is? I downloaded so long ago I can't remember, and googling it is no help. I don't even know what rom to apply it to.
Michael Morales
I'm guessing that's Pokemon Prism. I remember getting a file called Carl from that. No idea which version to apply it to though.

That makes sense. I think it was a Crystal hack, but I'm not sure. I'm sure it was gen 2, though.

Well, I used it on a USA version of Crystal, but it didn't do anything aside from break the game once you get past Oaks initial dialogue. I also found out I already have a Prism rom, but I don't know if it is the latest one or was some kind of early demo.

Apparently only some emulators are supported. VBA won't work. Try BGB: bgb.bircd.org

Oh, I got the Prism rom I already had to work. It's just the one I just patched, which I'm not sure if it's actually a Prism patch or I used the right rom.
