EPIC DOS games patch program

We found that there are some EPIC DOS games can not detect PCI
audio. This is due to these games using instruction loop as time
counter not a real constant period. In high speed CPU PC, the loop
time become shorter. That is reason that games can not detect PCI
audio. If you meet this problem, please run patch program to fix.
All of fixed files will backup to *.old.
