Just one of those things you happen to see when browsing by and going 'hm...'
I remember some discussion about games requiring ECS and my disk working on my A600 but not my A500.
If
this information is correct, then the 2.0 requirement could have made people think it requires ECS and that's the explanation.
Sorry, can't test this right now because my A500 2.0 machine is being modded. But should be easy to confirm with a bare bones normal A500 with trapdoor RAM.
