1) First you will need a raspberry pi B+ keyboard usb logitech game pad or generic, program buttons for menu when u get to boot stage.

Go to site download sd image retropie 1 ' '

Second you will need to download go to site win32 disk imager ' ' 16gb sd card needed to 'write' image to hd or usb to sd.

Boot raspberry pi B+ program directional button selection white screen
will pop up asking you to do keyboard or game pad you can program, the game pad later use keyboard first get to know the program read & youtube retropie.

you will also need a usb sound blaster here are some of the sites & code I used :-


Audio Test any wav file:

alsamixer: aplay -d plughw:1,0 /home/pi/starwars.wav sudo nano /ect/modprobe.d/alsa-base.conf

Audio settings:

/etc sudo nano retroarch.cfg

More performance:

audio_enable = true audio_out_rate = 22050 audio_driver = sdl audio_sync = true

Update to the latest Retropie Retropie setup script & all other instructions should be on the site petrockblock blog site.

Manually install retroarch this program makes it easy to set settings in games.

USB Thumb drive Edit rom folders & other :-
**** **** nano /opt/retropie/supplementary/ESConfigEdit/testfiles

prob solved itlest for edit use: sudo find / -name es_systems.cfg Two fils came up

This one works: sudo nano /etc/emulationstation/es_systems.cfg

sudo nano /opt/retropie/supplementary/ESConfigEdit/testfiles/es_systems.cfg sudo reboot sudo shutdown -h now.

vid modes making sure it's vid mode '1' eg for usb & vid modes all EMU's look for 1 make sure it is 1 ,usb look for PATH there are two you need to change for each of them.


DESCNAME=Atari 800
NAME=atari800 PATH=/media/usb/atari800 EXTENSION=.xex .XEX COMMAND=/home/pi/RetroPie/supplementary/runcommand/ 1 "/home/pi/RetroPie/emulators/atari800-3.0.0/installdir/bin/atari800 %ROM%" PLATFORMID=22.

2) Game controls you need to keep some of the screw points to fit a horse shoe circuit board using tac switches & the old rubber shoes, from the old sega I did have a lot of old sega's to make up for my buttons you may have to mod you model you could use other switches for you buttons look at my red buttons these just had two connections & could be easier to get hold of. Once done take you mame controller board from arcade world & wire up your buttons try to put all grounded wires together from one side of the horse shoe to the other side I had two to make it easier for me look at solider points diagonally across -+ for tac switches.

3) Heat sink kit for overclock peal of protection & stick big heat sink on the big cpu middle chip on the raspberry pi the little one is for the volt controller but is not needed for the b+. Important not responsible for overclocking do at your risk their are site included in my Software site's & web addresses I went to googleing.

4) Sega case you need a dremel tool to take as much plastic away battery compartments away as possible any edging must be removed &, later make fit with dremel all boards wiring using them as a guide to were you mite put them as some boards mite be different sizes eg hdmi board if you have a silver painted inside case you must insulate inside as I had that problem other wise try buy a old part sega orange inside or other.

5) Adafruit battery's 2x li-ion 6600mah 500c boost converter & charge unit Instruction are on this site :-
I attached this by Velcro sticky strips.

6)Have a good look at the pictures & links in Software site's & web addresses I googled also adafruit products have very good instructions to follow.

Your model mite be differ to mine eg buttons game case & most important have fun.
