Labyrinth updates
-----------------

0.50

- Complete rewrite of a very old version.

1.00

- Added sound emulation.
- Now runs in mode 27 instead of 28 : colours are not slightly 'tinted' anymore
  (standard 256 colour palettes don't have pure 100% red, green or blue ...),
  and scrolling is faster since only half the data needs to be moved around.
- Now exports percentage of processor time used (Labyrinth%Performance).

1.01

- Slight speedup of sound emulation (code only, not quality).

1.02

- Removed original Labyrinth BBC code. Supplied extraction code for downloads.

1.03

- Real time behaviour slightly more accurate : synchronisation calculations
  more accurate, and now synchronising before every write to the sound chip.
- Now using ZeriBeep 1.10.

1.04

- A game can now be saved by pressing 'Print Scrn' when in the main game.

1.05

- When loading a saved game a flashing cursor would (but shouldn't) show.
- Flashing when completing a level set now works (maybe slightly off in
  speed but not significantly).

1.10

- More realistic system VIA T1-low counter values (used as a random number by
  Labyrinth). Now based on the 6502 cycle counter instead of a fixed change per
  read.

1.20

- Adapted to ZeriBeep 1.30, but no significant changes.
