[Review] Nintendo Wii U Pro Controller with RetroPie

January 26, 2017 0 comments

Since I have been dabbling in the whole RaspberryPi / RetroPie / EmulationStation world, I wanted to have the best wireless controller.  Why?  because it’s not the 90’s any more and people aren’t sitting on the floor in front of their televisions.  My TV is mounted above the fire place on the wall so to have a silly USB cable coming down while my two kids are running around isn’t practical.

I also wanted a bluetooth wireless controller that was just going to work and always work even if I had to spend $30-40 bucks.  I’ve tried over 10 different controllers from 8bitdo, to Dualshock PS3, and the OEM Xbox 360 controller.  Out of every single controller I tried I always went back to the Nintendo Wii U PRO.  It just felt right in my hands, the controls and buttons are perfect there is no delay.  I even left the system running for 8 hours I came back and the controller was still powered on and responsive.

I’m a huge fan of Nintendo 64 emulation so I’ve been looking for a system that could handle the ROMs and emulators on the big screen.  I’ve tried the Raspberry Pi2 which was still laggy but after testing the RaspberryPi3 it seems the lag has gone down tremendously.  One of my favorite games is Mario Kart 64 and the controller feels perfect.  It’s not the same as an official 64 controller with the Z trigger on the bottom or shape.  Instead the controls are your RB/LB buttons and gas utilizes the B button.

So out of all the controllers I demoed I will have to this is by far the best for use with the RetroPie/EmulationStation.  Be sure to make sure you by the official OEM version as there are several knock-offs.

Faster RetroPie Scraping

January 26, 2017 0 comments

Since I jump from different projects every single day I decided to purchase a RaspberryPi and try out the RetroPie emulation software.  The software allows for playing classic video game consoles such as Nintendo, Super Nintendo, Atari 2600, Atari Lynx, MAME Arcade games, Nintendo 64, Sega MegaDrive, Sega Genesis, Nintendo 64 and PlayStation 1 and many more.

I loved the whole idea that it would showcase the different games cover art.  However when you have over 3000+ games installed I couldn’t sit there for days and continue to hit the “A” button to download the correct metadata.  Since Google is amazing, I decided to browse for an easier method of grabbing all of the metadata.  I came across this blog by Stephen Selph

This is an auto-scraper that runs from a command line that supports:
NES, SNES, N64, GB, GBC, GBA, MD, SMS, 32X, GG, PCE, A2600, LNX, MAME(see below) ROMs

I decided to write my own tutorial on how to achieve this using his software.

Step 1.  The first step you need to do is make sure your RaspberryPi is connected to the internet either via Ethernet or Wireless (ethernet) preferred.

Step 2.  We now need to find out our RaspberryPi or RetroPie’s current IP address.  You can find this out by going to the main menu of the RetroPie interface and choosing “Show IP Information”.   If you can’t find this screen you need to go to your system console list and choose “RetroPie” this is how you access the RetroPie interface menu.  Choose “Show IP Address”.  You should now have your IP  i.e  (

Step 3.  Now you need to download Putty so you can SSH into your RaspberryPi / RetroPie.  Once you have downloaded and installed Putty, launch the Putty application and enter your RetroPi’s IP Address information.  Then Press “Open“.

Login as username “pi” and password “raspberry”.

You are now successfully logged in to your RetroPie

Step 4.   Next you want to make sure no instances of EmulationStation are running.  Type the following command and press “Enter“.

ps -u pi

If your screen looks similar to the above and you do not see “EmulationStation” your good.  If EmulationStation is still running you need to use the following command to End it.

killall emulationstation

Step 5.  Next we need to install the proper scraper script.  Navigate to https://github.com/sselph/scraper/releases Since i’m using a RaspberryPi 3 I’m going to install:  https://github.com/sselph/scraper/releases/download/v1.2.1/scraper_rpi2.zip.  Now we are going to use the following command to install the script to RetroPie.

wget https://github.com/sselph/scraper/releases/download/v1.2.1/scraper_rpi2.zip

Type in the code above and press Enter, you should see something similar to the screenshot below.

Step 6.  We now need to unzip the script that we just transferred to the RetroPi.  Do that by type in the following command and pressing Enter.

sudo unzip scraper_rpi2.zip scraper -d /usr/local/bin/

You should have something similar to the screenshot posted below:

Step 7.  Alright now that the script is installed and unzipped on your RetroPie, it’s time to put it to use.  You have 2 options you can scrape all the consoles or you can navigate to the specific console you want to scrape.  So in this tutorial I started with SNES (Super Nintendo).  Follow the following commands to get you there:

cd RetroPie
cd roms
cd snes

Running the last command once you are in the SNES directory will display all of the ROMs you have installed on your RetroPie.  Like shown below:

Step 8.   Now we are going to run the following Scraper command to scrape all the metadata for the SNES directory.

scraper -thumb_only

You should now see something similar to the screenshot above.

Step 9 (Optional).  If you want to scrape all of your consoles run the following command.

scraper -scrape_all -thumb_only

Once you reboot your RaspberryPi or RetroPie, you should notice all of your cover art successfully downloaded.

You can scrape all systems with this command:
