I went through this retro exercise almost 2 years ago. My parents told me to get my crap out of their basement (moved out 12 years ago) and it turned out to be all of my consoles. 2 NES, 1 SNES, 1 TG16 and 1 Sega Genesis and tons of games. Set up the TV downstairs and spent my nights reliving my childhood. get the everdrives for them all and set that up as well. Around the same time, I was building a MAME cabinet so I added all of them to my Hyperspin setup and kind of forgot about he old consoles. I love my retro games but I am fine with playing them on a cabinet, LCD or my main TV in the living room.
Fast forward a bit and since then I have built a mini Cupcade, put a PC (Intel NUC) in an NES (for movies mainly, but I game as well) and my latest endeavor was putting a mini-itx PC in a PS2. I have movie nights outside and wanted something different to play my movie son so I built this and, of course, added a sized down Hyperspin. I have no issues with blurriness or anything on my projector outside. It made its debut last night. Watched Joe Dirt 2 and played some Sunset Riders. Now I just need to build a control panel to use when I play.
