Checked some bootleg hacks of King of Fighters 2002, and revisited my dear CV Chronicles
In "10th anniversary version" or "KOF 2005 unique" bootleg versions, expanding the existing parameter of original version characters is actually an interesting idea, but player version of Rugal sucks (The motion of Bead Destruction and Kaiser Wave are as slow as taking shit, Genocide Cutter only 2 hits)
The boss version Rugal seems normal, but defense level is paper level (like player version) when controlled by players. And in Practice mode, if Boss Rugal chosen, player Rugal will come instead. I think there's a Boss switch that keeps the Boss Rugal with normal/boss level defense is unique to CPU, but that's nothing important at all. Both version of Rugal in "2005 unique" sucks.
Also I like the VA of 2002 Rugal because he's the same person who did Dracula's Japanese VA in SotN and I can, actually, feel some Dracula in it. It's a shame that Rugal's VA changed to a new-recorded one in 2002UM.
