Hmm, well I finally managed to defeat him using a Rising Tackle/Burn Knuckle combo... still, it was a close match.. he defeated me in the first round, then we went through two double KOs and I managed to take him out in the final round. Is it true that to get the real ending you need to beat the game without continuing? Does loading the memory card save count? If so, I need a lot of practice...
I had already figured out the 'power wave as they get up' thing, but I hadn't thought of tacking a burn knuckle onto that. Is that the A version or C version of the BK?
Anyway, thanks for the advice, guys. I played this game once in awhile in the arcades back in the day, but now I'm just starting to appreciate it.. it just feels better than SF2 in some ways. I guess it's kind of like fine wine.. it just gets better as it ages! Now I just need to get my hands on FFS....
