Found the purpose of dummy files!

This is what I read:

"Dummied games and dummy files refer to the practice of filling out the center of the CD with empty space so that the game data is pushed to the OUTSIDE of the CD. CD-ROM readers read the data on the OUTSIDE of a CD faster than on the inside... Non-dummied games take longer to boot, load, and sometimes have the ill effect of not being able to load the game textures fast enough during play, resulting in missing textures, slowdown, and general visual weirdness. "

Usually I just play mounted backups on Chanka, but if you eventually want to burn them to CD then you don't want to delete the dummy files? Does anyone know how fast the DC's GD-ROM drive is? Maybe current CD drives are faster so you don't need dummy files anymore...

Man on a mission
Dummy files aren't used because the DC's GD-ROM was slow - moreover they were in place to compensate for its lack of RAM and therefore its limited buffering capabilities. The deal about outside and inside reads is just an old wives tale. You see, the DC not being able to buffer long sequential chunks of data (which is how CD/GD/DVD-ROMs are stored) some compensation had to be put into effect. Therefore the data is SPACED by Dummy data so the laser can read at certain intervals while the disc spins , as opposed to reading continuously like PC-CDROMs and the like do (Windows for example buffers at least 10MB - the DC just cannot do this).

So if you're playing your backups on Chankast with your CD-ROM drive, then you have no need for the dummy files?
