c.t.h. isn't being very clear. Once you complete King of Fighters R-2, what happens is the RPGish Making Mode is unlocked, and you can fight a kind of survival match to win some skills. These all do something cool, like there's Orochi's Mushiki that you can perform, pull out guns or throw grenades, increase your attack power, always start with 3 power stocks, etc. There are several moves that were Dreamcast exclusive, so unless you had the Dream Match 99, there was no way for you to get these skills. Some of them are kind of junky, like the ability to transform into other characters, which I really hated because they should have allowed you to change characters on the fly for Making Mode.
All the other stuff just allows you to trade points and what not.
I almost forgot, King of Fighters: Battle de Paradice and King of Fighters 99 (Japanese version) could link up, you could trade battle ability points, or unlock new strikers. For the Japanese version, I believe this was the only way for you to get strikers like Syo and Gai, and levelling up strikers on King of Fighters: Battle de Paradice was a lot quicker than collecting battle ability points on the Dreamcast game. That was probably the coolest use of that Dreamcast/NGPC link.
