WIP:

- 0.148: Luca Elia added clone King Derby (bootleg set 2). Changed description of clone 'Cow Race (1986 King Derby hack)' to 'Cow Race (King Derby hack)'.

- 0.147: Fixed for palette issues in King Derby [Miodrag Milanovic].

- 0.146: Updated King Derby to use modern I8255 implementation instead of the legacy one [Fabio Priuli].

- 0.143u6: Angelo Salese improved sprites in King Derby and added preliminary 7-seg artwork.

- 0.138u2: Changed description of clone 'King Derby (1986 Taiwan bootleg)' to 'King Derby (Taiwan bootleg)'.

- 0.137: Angelo Salese implemented sound, 'key matrix' inputs and coins in clone King Derby (1986 Taiwan bootleg) and decrypted the the color prom. Game can be considered as working right now. Added 'Reset Backup RAM' dipswitch to King Derby (1981).

- 0.136u4: Team Europe and Dumping Union added clone King Derby (1986 Taiwan bootleg), not working. Changed description to of 'King Derby' to 'King Derby (1981)'.

- 0.131u2: Angelo Salese fixed King Derby sprites wrap-around and flip x positioning.

- 0.129u6: Stefan Lindberg and Angelo Salese fixed King Derby sprite colors. Added color prom ($0 - 512 bytes).

- 0.129u5: Stefan Lindberg, Andrew Gardner, Angelo Salese and Roberto Fresca added King Derby (Tazmi 1981). Tomasz Slanina and Angelo Salese provided color prom to Cow Race. Changed 'Cow Race' to clone 'Cow Race (hack of King Derby)'.

- 20th February 2009: Angelo Salese - Currently writing a driver for King Derby by Tatsumi with Andrew Gardner & Roberto Fresca. Initially this driver was going to nowhere (it uses 3x Z80), but after some exaustive work we got it. There's still lots of work to do, plus colors needs a undumped color prom (it's currently using the default MAME palette). And, if you were wondering, yes, this is the original version of Cow Race.

- 30th July 2008: Guru - Cow Race chips arrived to be decapped, thanks to Dox.

- 0.125u2: Removed Player 1.

- 0.111u1: Luca Elia added Cow Race (unknown 19??).

- 25th February 2005: Guru - Gate In / Cow Race arrived, purchased by Randy from a PCB Shop. Thanks to the donators for keeping up the support.
