Simple way to burn a multigames DVD with evolutionx beta 1.8.2594 or later:

1) Make an xiso with a folder for each game (no file in the root)
2) Burn the iso (I use cdrwin5).
3) Edit the evox.ini file and add this lines in the games section:
Line "Games On DVD Drive",2
SortStart
AutoAddItem "d:\"
SortEnd
4) Turn off the xbox
5) open the dvd drive, put the disc, and close.
6) In the evox menu, you can see and launch all the games on the DVD.

Pete.
