OCS/ECS mix-up

[that_punk_guy]

I think people tend to group ECS and OCS together because they were more compatible with each other than with AGA, and are considered part of the same era of 16-bit Amigas. But there are some differences, higher resolutions and I think someone said VGA modes were supported from ECS onwards.

Yeah, it's possible to write software that only works on one of them, but the ECS's backwards compatibility was much better than AGA's. So that's why people tend to group them together. It is annoying though, maybe when you see errors like that you should email the webmasters responsible? :-)
