CODE UPDATE : Chicago Gaming Company : MMR Version 2.1


Chicago Gaming Company has released version 2.1 update for MMR Remake.  A change log is not listed so I do not know what the update actually fixes or updates.  Many people have been asking for the Color display for the MMR.  I do not know if this update changes the green DMD to color.


This version includes the following enhancements and bug fixes:

1) Next generation graphics engine to support full color display upgrade and address previous screen tearing issue.
2) Addition of Castle Multiball jackpot voice call
3) Modifications to real time clock
4) Addition of adjustment for controlled playfield LEDs
5) Addition of adjustment for trough coil strength
6) Resolution of audio crackling issue
