dummied half-life is better.
 

Couldn´t autodummy it cause the first session is audio so I made a 179mb dummy-file (max), extracted the CDI (Muds-hl) with isobuster fired up latest nero - new - cd-rom (mixed mode won´t work since the audio files are not nero-compatible) added all files to the top right corner window - set priority high on all files except the dummy - write cd - done. Anyway the loading times are better and more silent overall so I recommend it.

Anyway it aint self-boot anymore so I wonder if I can use cdrwin to create a bin-image of the cd and then use bin2boot? A better method anyone? would have tried it but I don´t have cdrwin / CroCop

edit, worked it out dont need help
