GUI/OS for the Spectrum?Hi, Is anybody working on a WIMP/GUI system for the Spec? Is there anything current out there? [url]http://snakeoillabs.com/wordpress/2005/10/30/8…
[QUOTE=tstih;630116]1) Linear backbuffer. This means each drawing routine could be much faster since adding 32 would get you to next line and shifting 5 times left to random line.

Scrolling is a bit complicated to provide as a generic game engine. A linear buffer is one thing. Pointer access to it, where the source address is not hard-coded so you can move the pointer for a quick scroll, is another thing that takes more time. -
