Hi,

What is the better loader screen from speccy games?? or simply which is the screen you more remember..

I remember a lot the screen$ from Robocop and HeadOverHeels.. also GreenBeret.

Did any of you chaps write your own spectrum games or applications.

If yes , did any of you guys manage to get a preloading screen going.....

Does anyone know where I can get a screensaver called "Screen$" that apparently simulates a Speccy loading?

... , anyone got a windows98 bootup screen that looks like a spectrum ... tape loading screen? Will be cool isn't ... ?

Imagine...a grayish screen, with the sinclair copyright line ...

Spectrum games lacks ending screens mostly, but there may be some brilliant games with very good ending screens/demos. I'm now searching for them.

I like ending screen of captain blood and rainbow islands 2. I know there are better ones.
