Yes - use Dreamcast GDI to Mame CHD Converter from http://www.emutalk.net/threads/51502-GDI-to-CHD

I used it to convert Crazy taxi GDI (total uncompressed size 1.1gb) to a CHD file (118Mb) and it worked in Reicast.

edit - The version from the link is v4 I think (mame 0.139u3) - this is the info:

Thanks for that, did some research and it seems v5 was added in 0.145u1 of mame.
So we need to be using v145 for v4 with reicast as it contains the latest fixes up to v5.
