9 JUL-2003
10
11 Known issues:
12
13 - The main program is responsible for sprite clipping but occational
14 glitches can be seen at the top and bottom screen edges. (post rotate)
15
16 - B-Wings bosses sometimes flicker. (sync issue)
17
18 - The text layer has an unknown attribute. (needs verification)
19
20 - Zaviga's DIPs are incomplete. (manual missing)
