Any way you could add this to the Mameoxtras build?

Well i did add it for testing purposes to my own MAMEoXtras build before i then ported it across to the MAME2003+ core

Trust me the xbox does not have the power under the hood to emulate this game correctly it's unplayable more or less.

would it be playable in mameox 0.72?

with the hacked midway drivers?

Oh it doesn't use the midway drivers, it runs on Itech32 hardware being a joint effort between Midway and Incredible Technologies

funny enough i had it up and running in both MAMEoX72 and MAMEoXtras it performs the same more or less it both cores it's way

to slow to be playable on the xbox as per some other games in that driver like say Drivers Edge or Street Fighter The Movie.


TBH i never meant to support this one on the xbox as going how the above games performed and the fact there are no speedups for

the game and it uses some nifty photo realistic gfx as per NBA Jam etc etc i knew it was gonna be slow hence my target was always

just going to be add it to test it out make sure it works and then port it across MAME2003+.
