I also like to have models of the most popular non dedicated arcade cabinets. Here in the netherlands even in the eighties most of the cabs in our arcade were general cabs...so for a relastic recreation they are very importent :-)
I am not sure about using flyers or marquees on the sides...personally i prefer to keep the models as accurate as possible...so flyers on the sides...not for me...but...the real question is if i will support dynamic texturizing of the sides...and i probably will...it has never been a priority because not really nescessary...if this would be added you could put whatever on the sides like you can do now for screenshots and marquees. (Actually I allready made the hooks for it in the fe...shader 1= marquee, 2=screenshot, 3=bezel, 4= cpo, 5= left side 6= right side...but the models themself are not setup like this right now...)
