Re: R: R: Vector games on Laser show hardware

They're not cheap, but they appear to look great compared to some older mono
laser systems i've seen...

I realise that this system is undoubtedly running from MAME and not from a
real pcb... but i would hope it could be fudged to play from the real thing
:)
