Either modify the source code to no longer check for the CD, or modify the source code so that the regions are changed to NOCD mode.

Also, to get the text in English you'll need to modify the source code AGAIN, and re-enable the region hacks. Keep in mind that if you do any of this you will not get any support as doing this makes your build of MAME "custom" and therefore unsupported.
