0.143 [Stefan Lindberg]
0.35b11 [Carlos A. Lozano, Phil Stroffolino]

- 0.145: David Haywood fixed graphics corruption on both sides in debug mode of clones Terra Force (bootleg) and (Japan bootleg with additional Z80).
- 0.143u5: ShouTime verified correct sprite roms for clone Terra Force (Japan). Fixed rom names in clones.
- 0.143u1: Added gfx4 roms from Terra Force (Japan bootleg with additional Z80) to clone Terra Force (Japan), needs PCB verification.
- 0.143: ShouTime added Terra Force (Japan). Changed clone 'Terra Force (US set 2)' to parent 'Terra Force' and clone '(US set 1)' to '(US)'. Renamed (terraf) to (terrafb), (terrafa) to (terraf) and (terrafb) to (terrafjb).
- 0.142u2: Angelo Salese implemented MCU simulation to clones Terra Force (US set 1) and (US set 2). Hand-fixed bit-rot bit in Terra Force (bootleg), fixing the attract mode crash. Fixed emulation of the extra Z80 in clone Terra Force (Japan bootleg with additional Z80) (used as a replacement for the protection), promoting it to working. Bill D. and The Dumping Union redumped clone Terra Force (Japan bootleg with additional Z80) bitrotted rom. Changed description of 'Terra Force (set 1)' to 'Terra Force (bootleg)' and clones 'Terra Force (US)' to 'Terra Force (US set 1)', 'Terra Force (set 2)' to 'Terra Force (US set 2)' and 'Terra Force (bootleg with additional Z80)' to 'Terra Force (Japan bootleg with additional Z80)'.
- 23rd April 2011: Angelo Salese - Discovered and implemented sprite color cycling effects in ArmedF driver. That's a RAM-based clut table that look-ups via a byte in the sprite defs. As you can see from the YT vids, it's used for doing neat effects such as explosions / bonus colors etc. in Terra Force. It's even more useful in Kodure Ookami, since it's used to differentiate the explosive red ninjas from the normal ones and in Armed Formation, that is used to make the sprites to be a lot less static.
- 21st April 2011: Angelo Salese - Currently working at the Nichibutsu 1414M4 emulation, that is a fancy MCU / blitter device used for copying text strings in various 1987/1988 games. Here's Terra Force and Kodure Ookami with this hooked up.
- 0.125u6: David Haywood added clone Terra Force (bootleg with additional Z80).
- 0.123u2: RansAckeR added DIP locations to Terra Force.
- 15th December 2008: Tirino73 dumped Terra Force (bootleg with additional Z80). Note: The custom MCU of original was been replaced by a small daughterboard inversely connected to the main cpu board.It has a Z80B*,which uses 2kb of ram (6116 SRAM x1),and some standard TTL ICs.
- 0.122u8: Changed description to 'Terra Force (set 1)'.
- 0.114u4: Fixed rom names.
- 0.114u3: Stefan Lindberg added clone Terra Force (set 2).

- 31st July 2000: Guru - Dumped Terraforce (Alt, bootleg).
- 0.36b13: Added gfx5 rom ($0 - mcu/blitter data) and a prom ($0 - unknown).
- 0.36b4: Changed VSync to 57Hz.
- 0.35b11: Carlos A. Lozano and Phil Stroffolino added Terra Force (Nichibutsu 1987) and clone (US).
