Can you explain what this does for us not so smart people. Sounds exciting, but I have no clue.

These are just simple functions for drawing semi-transparent rectangles, pixels and iamges with an alpha channel.. Io can read an article about alpha channels here: http://en.wikipedia.org/wiki/Alpha_channel
Semi-transparent rectangles are just unifor-coloured bitmaps with a uniform alpha channel.

you forgot to add france.320x240x16.bmp
Comment by Pascal Briehl (ColdSphinX) - Saturday, 14 April 2007, 20:45 GMT+1
also aunknown.c
Comment by Ştefan Săftescu (SliMM) - Sunday, 15 April 2007, 12:47 GMT+1
Sorry for that. I'll remove aunknown.c from the patch, as that is just another test file. I'm new to patching. france.320x240x16.bmp is now attached. It's a picture from google, since I didn't want to attach the original one.
