DREAMCAST ISOS how to burn?

Hi just finished mastering making SATURN discs and i hoped in my other SEGA system the DREAMCAST.
I downloaded the ISO the name of the file which is
IKARUGA.NRG and my question is simple ?
If i burn with alcohol will i make a real DC game, i heard that some games need UTOPIA BOOT DISC , but i have just gotten a DC with modchip installed.
I don't think i need that DISC with a modchip.

Anyway i think if i burn like PSX games direct BURN IMAGE WIZARD will i make a DC game , i don't want to ruin any disc as i am ruining quite a lot lately(13 DISC until i made the correct SATURN game) so just someone tell me is it the same thing or should i do something different ????????

Many thanks in advance.

Even with a modchip you'll need the Utopia Boot Disc.

Some recent games (for example Sonic Adventure 2) don't require Boot Disks or modchips.

I downloaded the three versions of UTOPIA BOOT DISCS
1 .cdi
2 .ccd
3 .nrg
And what a pleasant coincidence i just downloaded Sonic Adventure 2 Alpha which is a little bit different than Sonic Adventure 2 in sound and in some levels, but i guess it's the same cause it said SELF-BOOT image.
I already found the way to burn them.Thanks belmont

99% of all Dreamcasts play backups WITHOUT a modchip. Selfbooting images don't need anything, others need the Utopia bootdisc.
