This is pretty much what you would expect - Oracle of Ages, Kaizo Edition. For those who don't know, Kaizo hacks are meant to be extremely difficult in nature. I don't think this is as hard as those Mario hacks, but I hope it provides a challenge to those who've played through Ages already.
At least, that's the ultimate goal. Right now all I have to offer is a demo going up to the end of the first dungeon. Although it's only the first dungeon, I've put a lot of work into it... especially into the boss.
The patch should be applied to a clean US rom. And, for anyone curious, I've also uploaded the source for my custom scripts and assembly hacks to github. The rest was done via ZOLE (zelda oracles level editor).DownloadSource
