Games which require exact screen timing

Some games require exact screen timing because they have a carefully timed border effect or because they have a critical timing for updating their screen.

1942

has a high color effect in the start screen. nice. :-)

Academy

Start menu with overscan border effect.

You must connect a Kempston interface to control the mouse pointer.

Aquaplane

Game with overscan border effect. Horizon extends to whole screen width.

Thing

Critical screen update timing.

Zythum

Critical screen update timing.

This game has also a 'snow' effect using the fact, that the ULA misses some bytes if the video ram is accessed to frequently by the CPU, enforced by setting the I register to point into the video ram. This effect is not emulated by zxsp, and i don't know of any emulator which does.
