I won a Raspberry Pi for getting 3rd place in the Open 7400 Logic Competition, of which HubCityLabs donated the Raspberry Pi. My initial project idea for it was to set up a wall mounted weather station. For the time being I thought I'd mess around with it and get somehwhat familiar on what I'm dealing with.


I downloaded the Rasbian image and wrote it to an SD card. It's recommended that the SD card is a minimum of class 4.

Everything is supported 'out of the box' with Rasbian so there's no fiddling around. After purchasing a HDMI cable and connecting it to the Pi, it still output video via the RCA jack instead. I opened up /boot/config.txt and set hdmi_safe=1 and voila, HDMI worked!

To mess around with it, I discovered RetroPie. I picked the "slow" option which compiled all the binaries, rather than get the precompiled binaries. I didn't watch it intesnely, but it seemed to take about an hour. Once that's installed, you can now play SNES, NES, GBA and Atari 2600 games! RetroPie installs the emulators to ~/RetroPie/emulators and all the libraries to ~/RetroPie/emulatorcores. I downloaded Super Mario World and ran:

~/RetroPie/emulators/RetroArch/retroarch -L ~/RetroPie/emulatorcores/pocketsnes-libretro/libretro.so path_to_snes_rom.smc


To explain, it uses the RetroArch emulator and the pocketsnes library.

Here's the result:

I don't have a gamepade of any sort, so I just used the keyboard. The letters on the keyboard correspond to the controller (X is X on the controller, A is A, etc...). I had the GPU set to 128MB and it seemed to run fine. I overclocked it another 100Mhz just to see any performance gains, but I didn't notice any and it ran about 5 degrees hotter than stock.
