Hack description

MTPO Milli Hack

Description: The default MTPO fight time reporting uses a crude rounding technique. This hack allows for accurate millisecond timer reporting at the end of fights.

v2.0: added support for reporting Tyson fight time on victory screen.

v3.0: Replaced points counter with realtime last-punch-landed timer. It should not affect game timing/lag. I have seen instances of overrun ahead of actual round timer, this only appears to occur on knockdowns not ending the fight.

See the readme in zip for patch/assembly details.
