Put ColecOO.SIM in your GAME directory. Put your .COL games where you want.
Use "Interesting game" from Dingoo menu and choose your .COL file, the emu will launch with the game

Again, i used s2d sdk to make this emulator because i can't do some nice sound without it.
You can see my webpage about it here : ColeCOO For Dingoo. Also, the website is in French
