A little over a year ago, I purchased the ArPiCade unit from HighScoreSaves.com and installed it into my Donkey Kong cab. I rotated the sanyo ezv20 to horizontal and incorporated a VS. panel that originally came with this cab years ago, set the arpicade with 24 nintendo VS. games and was quickly impressed with how good emulation can be in the RGB realm. Played excitebike to death and felt no lag, saw no screen tearing or jitteryness in the scrolling, things just played well. That was my first dive into a pi.
About a month ago I had a work delivery near a microcenter and made my run through and they had a bin full of pi3B's for $30, didn't know it was that cheap and snagged one and found some zebra black ice case that was open and priced at $6 (all parts were there) on the bargain bin. Played around with a couple of the popular premade hip images that the kids dig and learned the ssh thing along with some other stuff, but I just couldn't play the games via hdmi. I did enjoy some of the pretty menus and all the historical information you could read for each game and system.
I did a search for s-video on the pi and figured I'd run into some easy hackery way to accomplish it... Nope, but I did discover the RetroTink hat (pi hat was another completely new term for me) and ordered one up, yes a bit pricey, I was curious though.
Received the RetroTink hat and luckilly that bargain bin case had a cut out for hat's, yay me. Booted the pre configured version of lakka from the RetroTink site and I was instantly impressed.
Learned that the maker of the bargain bin case (C4 Labs) has an etsy.com store and they sell an expansion kit to the case I had already that could be customized for a pi hat. Worked out ok.
I used the 1/8" audio jack for about a week, but instantly saw its short comings. It didn't output a full signal and the jack was scratchy and sucked. Had a planned trip to Fry's to grab some components and found a Sabrent usb audio dongle for $4.99, did a quick google search and saw people use them with a pi. I can't recommend this little thing enough, sounds great through my system, nice strong full range signal.
I didn't like that the audio dongle was too wide and rendered the next usb port useless, dug up a 6' usb extension cable from my stash and made it 3" attaching it to the side of the case with double sided clear vhb tape.
The low res lakka/retroarch menus are fine and look like an everdrive menu. This thing is ready to launch a game 8sec after power up and switching from game to game or launching a game from another system happens instantly, it's like a multi-system-everdrive :p . While I was trying the pre configured bloat stuff via hdmi you could tell there was just too much sh!t going on. I'd go to quit a game (select/start) and the screen would go black for 7seconds til it got back to reloading all that sh!t to get back to the menu and within that time span I'd forget what game I wanted to play next.
I didn't know a pi does ps1 emulation quite well, found myself in the garage digging through boxes hunting down my old favorite driving controller from 20 years ago. I remember buying that blue usb thingy in the early 2000's so I could use the controller to play pc driving games on the cash register pc's at a retail job I had. The pi saw the set-up instantly and was off and running reliving some colin mcrae and gran turismo2 memories.
Everything just looks awesome on my gaming crt.
When I was at Fry's I also grabbed some extra s-video cables and dug up the $2 s-video switcher thrift store find and have been A/B'ing the consoles I have on the fly. Quite impressive how good this set up is.
It was a curiosity that really worked out well and is a gap filler for me. I've got 7800, TG16, NeoGeo aes, SNES and some old sony ps1 favorites loaded up on this thing. Emulation can be a fun thing when you don't integer scale, stretch, scanline, shader, wait for sync with overlays and you just ask a system to run the game and spit out an RGB signal and stay in the 240 realm.
good day.
