- 0.116u2: Justin Kerk and Lord Nightmare updated Lasso to correctly use the SN76489 instead of the SN76496, which was a later design.
- 0.61: Fixed cpu2/3 rom loading and visible area to 224x256. Added dipswitches 'Coin B', 'Warm-Up Instructions', 'Warm-Up', 'Warm-Up Language' and 'Invulnerability'.
- 0.56: Changed visible area to 223x256.
- 0.37b2: Phil Stroffolino added sound and fixed colors in Lasso. Changed the M6502 CPU1/2 clock speeds to 2MHz and the M6502 CPU3 to 600000 Hz. Replaced AY-8910 sound with 2x SN76496 (2MHz) and changed palettesize from 64 colors.
- 5th May 2000: Nicola Salmoria fixed the Lasso vertical throw bug.
- 4th May 2000: Nicola Salmoria added sound to Lasso. Phil Stroffolino fixed Lasso color palette and added cocktail support.
- 0.36RC2: Phil Stroffolino added Lasso (SNK 1982). TODO: Lasso can't be slung up/down (left/right works fine). Sound isn't hooked up. Imperfect color. Background color, lasso color arbitrary. Priority of lasso bitmap plane relative to background/sprites unknown. Possible timing problems. Input port issues: see fire buttons on high score entry screen.
- 6th March 2000: Phil Stroffolino sent in a driver for Lasso, and make some tilemap bugfixes.
