It uses a Raspberry Pi Zero, and an Adafruit 1.8&quot; screen for displaying. The screen size is 160x128, so PICO-8 fits perfectly (alright, centered). The buttons and button PCB are robbed from a USB NES controller I had. The case is 3D printed to fit the parts (very tightly). Total size of the unit is 120x45x20mm.</p> <p><a href="https://www.lexaloffle.com/bbs/files/9518/picoBoy1.JPG"><img style="" border=0 src="https://www.lexaloffle.com/bbs/files/9518/picoBoy1.JPG" width=320 height=240 alt="" /></a><a href="https://www.lexaloffle.com/bbs/files/9518/picoBoy2.JPG"><img style="" border=0 src="https://www.lexaloffle.com/bbs/files/9518/picoBoy2.JPG" width=320 height=240 alt="" /></a></p> <p>The screen mirrors the output of the HDMI, so you can play with either the TV or built in screen. Currently, it has no internal battery, but I'd like to find a good lipo battery to add. In the meantime, I just connect a USB power stick.</p> <p><a href="https://www.lexaloffle.com/bbs/files/9518/picoBoy3.jpg"><img style="" border=0 src="https://www.lexaloffle.com/bbs/files/9518/picoBoy3.jpg" width=320 height=240 alt="" /></a><a href="https://www.lexaloffle.com/bbs/files/9518/picoBoy4.JPG"><img style="" border=0 src="https://www.lexaloffle.com/bbs/files/9518/picoBoy4.JPG" width=320 height=240 alt="" /></a></p> https://www.lexaloffle.com/bbs/?tid=3174 https://www.lexaloffle.com/bbs/?tid=3174 Tue, 29 Mar 2016 13:11:36 UTC _draw vertical flip <p>I'm trying to port Write Fight for playing on a cocktail cabinet (players at opposite ends of a face-up screen). So one of the things I want to do is write text &amp; HUD elements oriented to the player who collected it. Is there a function, such as camera(), where I could flip/rotate all draw calls until reset?</p> <p>I'm doing work-arounds in the meantime, but I thought I'd throw out the question.<br /> Thanks.</p> https://www.lexaloffle.com/bbs/?tid=1882 https://www.lexaloffle.com/bbs/?tid=1882 Mon, 27 Apr 2015 14:49:48 UTC Write Fight <p> <table><tr><td> <a href="/bbs/?pid=10213#p"> <img src="/bbs/thumbs/pico10212.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=10213#p"> Write Fight</a><br><br> by <a href="/bbs/?uid=9518"> mattfox12</a> <br><br><br> <a href="/bbs/?pid=10213#p"> [Click to Play]</a> </td></tr></table> </p> <p>Two-player deathmatch game.
