Copts and Robbers (c) 1981 Sirius *RESTORED*

Here's a restored nibble image of the Apple ][ game Copts and Robbers.

It contains the following alterations to the original disk:

  * Half-track data (1.5-F.5) has been realigned to whole-track
    boundaries (01-0F). Includes the following mods (in pseudo-sectors;
    tracks 01-0F use 4x4 encoding).

    (t0 s1) 0473: 03 -> 02 ;track 1.5 -> 1.0
    (t0 s1) 048F: BE -> BF ;balance checksum
    (t2 sa) 1E0D: 03 -> 02 ;track phase for reloading pages 8-F after winning
    (t8 s7) 83D5: 19 -> 18 ;level data track phase number
    (t8 s8) 8404: 15 -> 14 ;you win screen track phase number
    (t8 s8) 8412: 19 -> 18 ;same
    (t9 s7) 8FBD: 15 -> 14 ;initial track phase number (trk * 2)

  * Fixed an uninitialized inventory item bug (!) that caused the
    game to crash if the first thing that the player touched was
    the treasure room wall.

    (t1 s8) 1000: 85 92 85 94 -> 20 64 1E EA        ;jsr bugfix
    (t2 sa) 1E64: 7 FF's -> 85 8f 85 92 85 94 60 F8 ;clear $8F & balance csum

  * Fixed an invalid branch operand bug (!) that caused the game
    to crash after successfully completing a level.

    (t2 sa) 1E39: D8 -> FB ;don't jump into an operand!

Now you can enjoy authentic Sirius bootcode execution on an emulator. ;-)

-Have phun!
