r6197 adds a -createuncomphd option to chdman. It works identically to -createhd but the resulting CHD is not compressed and not write protected. Would everyone who complained about this (mizapf, I'm looking at you) please test this before I throw it over to MAME?
Any chance of a -createblankuncomphd, for those of us who are trying to bring up a new machine from scratch? Also, what is this mystical "inputoffs" thing? It isn't needed by -createblankhd, so what is it?
