WIP:
- 0.144: Added 'Test Switch' dipswitch.
- 0.141u2: Alex Jackson added MCFG_SCREEN_RAW_PARAMS to Twincobr driver, correcting their refresh rates. Changed VSync to 54.877858 Hz.
- 0.137u1: Changed VSync to 54Hz.
- 0.136u4: Stephane Humbert fixed dipswitches and inputs in Twin Cobra clones (after verification of the M68000 and Z80 code).
- 0.133u1: Renamed (twincobu) to (twincobru).
- 0.129u4: Fixed rom names.
- 13th May 2007: Mr. Do - Thanks to the BYOAC/CAG artwork, we have a release for Twin Cobra bezel.
- 0.80: Quench converted Twin Cobra to tilemaps, corrected savestate setup, little cleanups to the machine code and adjustments for TMS32010 internal data map. Changed TMS32010 clock speed to 3.5MHz.
- 5th February 2003: Guru - Kyukyoku Tiger (Taito 1987) arrived from Taucher for trojanizing the MCU.
- 0.62: Changed TMS32010 CPU3 clock speed to 14MHz.
- 0.61: Changed VSync to 54.877857Hz.
- 30th June 2002: Quench fixed a few things in the Twin Cobra driver.
- 0.37b6: Fixed cpu3 rom loading.
- 0.36b11: Added cpu3 DSP roms and 5x proms (sprite priority/control/attribute).
- 0.35RC2: Changed description to 'Twin Cobra (World)' and clones '(Romstar)' to '(US)' and 'Kyukyoku Tiger' to 'Kyukyoku Tiger (Japan)'.
- 16th March 1999: Quench fixed Twin Cobra from crashing.
- 0.35b3: Quench emulated the protection (TMS32010) in Twin Cobra, which is now fully playable. Added TMS32010 (3.5 MHz) and changed VSync to 56 Hz.
- 8th February 1999: Quench fixed clone KyuKyoku Tiger.
- 0.34b1: Quench added 'Twin Cobra (Taito)' (Taito 1987) and clones Twin Cobra (Romstar) and Kyukyoku Tiger. Changed parent description to 'Twin Cobra (Taito)'. Added all gfx roms from clone (Romstar) to the parent set. Known issues: Most enemies appear already destroyed. This is probably caused by the incomplete emulation of the protection microcontroller. Kyukyoku Tiger doesn't boot.
- 0.31: Nicola Salmoria added Twin Cobra (Testdriver).
- 13th January 1998: Quench dumped Twin Cobra (World).
