I think I've found the site you mean, it's a very nice resource but due to the aforementioned Trojans I'm reluctant to post a link!
Rich sent me both the non-working ROM in question from this thread and a new one with my ZXpand conversion kit. The non-working one doesn't work in my ZX80 either which makes it all the more bizarre it works in SirMorris's - the new one works perfectly.
Anyway thanks to SirMorris and Rich for putting together such an amazing bit of kit and for the excellent customer service!
