- Yes, they did run like AGA in the mode called "fmode=0". AGA behaves like
- ECS in that mode, voila.

-
- That's true, no use of better fetchmodi (good old games ran 50Hz on A500
- anyway).
-
- BUT: If C= wouldn't have been so silly and chosen different values for
- ddfstrt/ddfstp when running fmode!=0, old games/demos would be able to
- run in fmode=3!
-
- for saving 5 transistors they made aga incompatible in fmode!=0.

-
- No, at least the programmers doing the kernel nkow about it.
- And other people, if they are told, too.
