Kind of up to date:
Not yet finished, but (bad plan) playable!
Coin mech is working, 10p per play, but takes 20/50/£1 coins
Need to fix the marquee in place
Do the back cover/fans
Sort out an effective exit/back button on the current controls - I hate extra buttons, so I'll be using what's on the panel.
Calibrate my AimTrak and maybe fit the recoil option.
Sort out non-mame games, not many but I like the American Laser Games series, VirtuaCop and HOTD which I don't think work well in MAME - I have PC versions of HOTD2 and 3.
Most annoying job is to get the side art re-printed as apparently I can't count or measure
