RTG403994p

Short:        Patch for 40.3992 rtg.library (P96 2.1b)
Author:       ville9@softpres.org (Christian Sauer)
Uploader:     ville9 softpres org (Christian Sauer)
Type:         driver/video
Architecture: m68k-amigaos >= 3.0.0

The CyberGraphX emulation of Picasso96 (V2.1b) isn't sufficient for
running iFusion. The (undocumented) bitmap alignment flag of AllocBitMap()
isn't supported and 4 Byte TrueColor modes are added with a MaxDepth of 24
instead of 32 to the Amiga display database.
 It also fixes a jump table initialization which could lead to crashes of
WritePixelLine8() when called on native Amiga screens.
 As an official fix for this is now quite unlikely to appear, I decided
to release the patch I made myself.

 THIS PATCH IS COMPLETELY UNOFFICIAL. IT HAS NOT BE APPROVED BY TOBIAS ABT
