Asuka 120% Limit Over for Sega Saturn

[Pullmyfinger]

I was playing the original for the first time last night with a few friends and we really liked it, then I remembered that there was a hack that gave you extra moves and extra buttons.

Here's the link to the patch:

I get a "Size mismatch" error when I try to patch, as the Image I have is some 2kb bigger.

Has anyone patched successfully or played the hacked version? Is it worth the hassle of hunting it down?
