- 16th September 2005: David Haywood - Top Shooter appears to be running on hacked up Megadrive / Genesis hardware. Was this an actual Megadrive game? Or did they just use the hardware to make an arcade game? (It's a real arcade with Insert Coin text etc).

- 7th September: ClawGrip - Won two PCBs on eBay: Top Shooter (from Sun Mixing Co.) and Skat (a German cards game). I'll dump them as soon as I receive them.
