 -YP crashed when used together with VMM
  (memory allocations are now made with MEMF_PUBLIC to avoid this)

INTRODUCTION

The program YP is a player for YAFA animation files.
It has some features that let your AMIGA become a real multimedia machine:
-play directly from disk
  or
 preload the complete animation for maximum playback speed
-can use all AGA and CyberGraphX screenmodes
-has a special "batch file mode" (for LARGE anim shows!)
-can play frame-synchronous sound effects (ProTracker modules, 8SVX samples)
-performance-relevant routines are coded and carefully optimized in ASM
 (like C2P, Delta-decompression, RGB-to-8bit rendering etc.)
