These are the changes from ProTracker V1.2 to SHATracker V1.x :

IMPORTANT : V1.04 had a minor Bug .....

 When you saved a module, it would increase in size with 30 bytes for every
 empty sample in the song.
 This would offset the samples when you loaded it again and sound 'funny'
 This error has been found and then terminated (PSSSSSTT :^D ) !!!

 - Changed copperlists to make SHAT compatible with Kickstart 3.x
   And the AA chipset !!!

 - Important change:
   HelpFile layout has been chaged to a simple Textfile.
   At the moment you have to have PPMore in your search path and the file
   PSTTHelpText in ST-00: for the help to work.

 - I have also made an AmigaGuide version of the HelpFile.
   At the moment it is not very advanced, but there are some links in it
   And it is better than no Guide file :^)

 - Redesigned Graphics (Neat aren't they ?? )

 - Salvage song function removed (Nobody used it, and it isn't
   very nice to stomp the memory in a multitasking environment)

 - MIDI Routines removed (They didn't work !!!!!)

 - Redesigned and moved the VU-Meter bars (I thought they disturbed
   the Song data readouts)

 - Audiochannel SOLO function added, Just Hold Right Mousebutton and press
   the Left Mousebutton on the channel to SOLO
   (Inspirated but NOT stolen from PT2.1 by NOXIOUS)
