Crouching Tiger Hidden Dragon is a hack of KOF2002.The full name is CTHD2003 so there is no separate 2003 version. New Backgrounds, don't know about moves, but a lot of palette swapping. KOF10th: No, Ultra Plus and all those additional hacks make hidden characters playable, unlimited power etc. Useless. KOF2004 is a a hack of KOF2003, IIRC. Matrimelee kicks ass, but it has one of the cheapest bosses ever. Also known as Power Instinct 4, but very few people call it that. Sengoku/Sengoku2/Sengoku 3 (Sengoku Legends 2001) are side-scrolling beat-em'-ups with swords, ninja arts etc. Awesome to the max. Sengoku 3 is the best of them. Sengoku 2 has a bug that occurs in every emulator (sounds fades away after the first teleporter on Stage 1. If you want my opinion, these hacks are worthless unless you are a collector and must have all the sets. These hacks offer way too little new substance in the form of new backgrounds, new titles screen, lots of palette swapping and maybe some moves switched around or having their commands altered. There are no new moves that have never been seen anywhere else.
