just look at the Zero-terminated shell at $8D84 (defined as USGSHELL in Usgard.H)  To hide this, you would have to write over it after Usgard has read from it and loaded the shell.
	There's no reason that the shells will cause any incompatibilities!  They're just interfaces to run programs, they don't have any functions, etc!
