Thanks for the list. Isn't Agony and other parallax games just using 6 bit planes in stock dual playfield mode? Agony doesn't look like 64 colours bobs + copper lists really. Lionheart used another trick to get round the 16+16 foregroung/background limit too I believe.
Most likely, I haven't got round to trying them all myself yet to actually see if they're EHB, Agony, Lionhart I didn't try at all.. and Pirates was reviewed as EHB, but my from my memroy of it I don't really remeber if it actually was..the rest should pretty much be EHB..
There's still a few others.. one more just came to me, Wing Commander ECS is also probably EHB as well.. I was making a list of all the EHB/HAM games, based on what I remeber/rumors etc.. but can't seem to find it.. If I do find it I'll add in the rest.
