- 0.115u3: Zsolt Vasvari fixed PIA numbers in revamped Spiders driver.

Added notifications for when the display enable pin changes in order to drive blanking signals. Changed visible area to 256x256 and VSync to 85.449219 Hz.

- 0.33b5: Keith Wilkins added Spiders (Sigma 1981). Spiders has a fully bitmapped display and all sprite drawing is handled by the CPU hence no gfxdecode is done on the sprite ROMS, the CPU accesses them via PIA2. Screen is arranged in three memory areas with three bits being combined from each area to produce a 3bit colour send directly to the screen.
- 29th April 1998: Mike Coates dumped Spiders (set 2).
