Dear Megalexxx or anybody can help me, excuse my English I write from Italy, so...

I read a lot of faq about Dj4 setting to burn Dc cdi.
But there isn't a similar idea.
Everybody write different method, so I go crazy!
Please I need a complete setting method working.
I need to know if I need to select overburn option or cd+g or Raw or Mode 1 or 2, bytes and so......PLEASE
A second question is about Ikaruga, I tried to burn cdi file in many mode, but everytime game block in the blank sega logo.
Why?
I use a Dc pal with Rf unit.
I don't know if is a jap or pal version(50 or 60)?
The only thing that I know is an about autobooting game.
I try to open image with cdmage but Pc go crazy?????
Help me please.
Hello from Italy.
