Hey all. Thanks for the positive comments... i've not touched it since i got Call of Duty, but i've had a break from that this weekend so have been having a blast on this.
I've not really changed anything on it, but have been looking round for other systems to emulate... it turns out that if i get some actual MAME games (i.e. as if they were running on an arcade machine), some of them expect you to add credits - which is simulated by pressing a given button on the keyboard. I can work backwards from this and hook that up to my coin mech, meaning you have to pay per play rather than just to switch the PC on...! Awesome!
Was a bit gutted today though - i finally found a copy of Virtua Cop 2 for the dreamcast to download- so i hooked up the lightgun and... lightguns dont work with LCD screens.
Lastly, i've just looked at my pics again... im suprised no-one noticed the knuckle dusters in the last pic, on the shelf on the left! Oops.
