I made a pi powered bartop arcade machine last year and when I decided to start using blender it was the first thing I made that wasn't from a tutorial. Thought it would be a good project to start off with as if I ever decide to make a new one I can swap the art out to get a fairly good idea of what it should end up looking like. I did make some huge errors, such as making the buttons as close to real in shape as possible, meaning there are over a million verts, mostly in the buttons !
thirddimension It's still one of my favourites of all time. I plan to remove the pi from the machine at some point and install a PC so I can add my launchbox drive to it and relive everything from my 48k Spectrum to the Dreamcast. Might even make another one with different art but I seriously need to redo the mesh as those buttons are a nightmare!
Contra 3 my fav on SNES
I'm aging myself...but this was one of my favorite games on the Sega genesis. Once in awhile I find a rom of it and play it.
