Chocks Away Extra Missions

Show all headers | View raw

Greetings, fellow gamers!

I have just released a patch for Chocks Away Extra Missions. It fixes a number of errors in the game’s graphics rendering code. You can now see how the game was originally intended to look!

The following errors are fixed:

Thick lines were not clipped correctly at the righthand edge of the screen, which meant that up to one pixel could spill from the end of each raster line to the start of the next.

A subroutine used to do perspective projection when generating thick patterned lines (for roads and railways) corrupted the input depth value when the point to be projected was distant. The effect was to make distant lines thicker than those in the middle distance (and also brighter, in the case of parallel lines).
