Has anyone finished MS5 on 1 credit?

If so, how did you do it? What sort of strategies did you employ for the last two bosses? I'm beginning to think this is an impossible feat.

I manage to do well enough leading up to the thank desert tank boss. For the life of me, I just can't seem to time/dodge those damned falling fireballs. The last boss isn't overly difficult (in his winged form), but the part right before him with the two towers always seems to cost me a few lives.

Here. Except the video has been taken down.

Was the video from someone playing the real thing (AES or MVS hardware) or off some emulated rom?

rom, but they claimed to not use any cheats or slowdown or savestates. i have the vid on my harddrive if you want to try to get it through aim or something.
kafgaira is the name.
