@rbaker have a good day take care

@montanafury No worries. I'm no expert. Just trying to help. It can be a steep learning curve... but worth it.

I prefer the Steven Selph scraper too. The built in scraper pretty much sucks (not RetroPie's fault, it's built into EmulationStation). The built in is too slow, and it's fuzzy logic is terrible. Whenever it doesn't have an EXACT 100% match, it prompts you for the game, even when there is only 1 game on the list. Steven's is much faster, requiring no user input. The fuzzy logic built into that one is like 99% accurate. I've not come across any mismatched games, but the scraper doesn't find them all. A lot of Japanese games just fail "hash checks". I haven't figured out a way around that, other than scrape with Selph's first, then go back in and use the built-in one.

But the other replies are correct. Before I started building my setup, I went through the WIKI and DOCUMENTATION. In fact, just about everything is already covered in the video on the homepage's link to Installation:

@cyperghost You mean this post? I used the Adafruit retrogame software for the GPIO to keyboard stuff. It was easy.

@meleu Came back to do it but it looks like a mod beat me to it. Thanks again.

@BuZz Very true ;) Clearly a Meat Based Problem / PEBCAK....

@GtBFilms Thanks for the info. I had a look at the ROM libraries I have for the emulator on my Mac and they don't even total 1GB, so that will give me plenty of room for other 'stuff'.

I've borrowed a keyboard from work so I have that and the memory card in my possession: the RPi was delivered today but whilst at work, so it's at our local depot.

Looking forward to getting my hands on it and getting started now: I have the Retropie installer downloaded and Retropie itself, my ROMS are all in situ and ready to go: so now it's just a case of build, install/setup and hopefully I'll be good to go!

I like the idea of having it connected to WiFi, I'm not going to install a tonne of ROMS, just my old faves and a few never-played titles, so being able to transfer one or two wirelessly now and again would be really handy. Plus it is 2016, so really WiFi setup should be a given!

Thanks for your help: no doubt I'll have more questions thrown up after installation, but fingers crossed it all goes ok!

@thatdamnlobster if your problem is solved you should mark this post as solved. ;-)

Well take a look at my latest build. You just have to connect one Bluetooth stick and can buy two controllers. The build provides good portability and does not cost so much.

Anyway your design idea looks great but for what do you need annother OS? RetroPie is based an Raspian and you can install a GUI :)

I assume you're trolling me. I think I put it on Kiosk mode. I tried your Konami code, but it doesn't seem to be doing anything. -_-

@dankcushions I've managed to get it working now. Needed to unzip the file!

Now to move the roms over. ( God help me)

Thank you for your help!
