If it's anything like the VC Game then it's definite a pain to hack especially with the health address changing every round. I'm still working on Samurai Shodown 2 on Neo Geo VC
this games setup like the ps2 version it was also a pain.
Ps2 version used a built in Emu..
i just used Scrub to look on the disc and ya its using an emu.. a fun hack :P
i will try and check it out tomorrow
