[Munis]

I have burned dreamcast backups a few times with no problem at all.

But today after i had downloaded BASEBALL 2K2 i first converted the
CDI. file to a NRG. file (nero) and then burned it with nero.

But when i was going to play the game it didnt work at all!!!!
First the Dreamcast logo apeared on the TV, and then the Sega logo
apeared, but after that nothing happend and the Dreamcast logo
apeared again followed after the sega logo again. And the same thing
just keeps on going and going............The game never
starts!!!!!!!!!!!

I have burned on 4x and 8x. And used vivastar cdr's and also
unbranded cdr's. I have also tried with 3 diffrent games and all
have done the same damn thing. I hane never before had this
problem!!!!!

What the hell am i doing wrong?????????

Please help me!!!!!
