[Help] Removing Dummy Files

I have a some Dreamcast roms in cdi format and i would like to remove the useless Dummy file inside the image because I am playing it with an emulator.

Another Question, Im wondering if anyone could somehow modify the VMS.bin files so they can hold more than 200 blocks

TY

I'm not sure what effect removing the dummy files would have on an emulator, much less if its even possible without the hacking tools and knowledge used to put them there.

I think even on an emulated system they may play an important part in getting the game to be read, and play correctly.. Maybe some emulators out there may be more flexible but I would -hope- the ones that are active are striving for accuracy in emulating the DC, in which case the dummy files would be necesarry to trick the emulator just like the real system might need to be tricked.
