0.108u3 [AGEMAME]

WIP:

- 0.143u2: Renamed (connect4) to (m4conn4).

- 0.143: James Wallace used a Dolbeck Systems flyer to correct the colours of the Connect 4 built-in layout.

- 0.133u5: AGEMAME improved the Connect 4 layout.

- 0.128u5: Aaron Giles fixed Connect 4, which crashes if NVRAM file is present.

- 0.123u3: Aaron Giles fixed crash in Connect 4.

- 0.116u4: Improved Connect4 layout [James Wallace, Atari Ace].

- 0.115u3: Luigi30 fixed AY8910_read_port in Connect 4.

- 0.112u2: Added dipswitches 'Invert Alpha?', 'DIL101 - DIL107' and 'DIL201 - DIL208'.

- 10th February 2007: James Wallace - Improved input timing. It appears Connect 4 uses a different sound mapping to regular Barcrest games.

- 0.111u6: James Wallace fixed assertion in MPU4 driver. Fixed the mechanical meter operation, enabling coin entry in Connect 4 - Game now playable.

- 24th January 2007: James Wallace - With thanks to Canonman and Highwayman, I was able to confirm a seemingly ghastly misuse of a PIA is actually on the real hardware. This fixes the meters.

- 0.108u3: El Condor added 'Connect 4' (Dolbeck Systems 198?).
