GPIO RGB DAC Hat & Appropriate RGB/YPrBr cable
5v 2.5A Micro USB power supply (Element14 recommended)
4GB+ SD Card
Optional Prerequisites: Install these prior to installing the CRTPi zips!
Install the following theme: /ruckage/snes-mini/
Install the following opt packages: scummvm, lr-beetle-wswan, lr-fbalpha2012, lr-mame2000, lr-mame2010, lr-nxengine, lr-ppsspp, lr-prboom, lr-snes9x2002, lr-tgbdual, lr-tyrquake, scraper, skyscraper
Install the following experimental packages: lr-mame2003-plus
Install libxpm-dev and libx11-dev: "sudo apt-get install libxpm-dev && sudo apt-get install libx11-dev"
Install MUNT (MT-32 Emulation) using this guide: https://retropie.org.uk/forum/topic/12549/tutorial-installing-munt-mt-32-emulation-on-rpi-3 (Remove 'qtmobility-dev' from step 1) (mt32roms.zip in master is for step 10)
Instructions: This is recommended to be installed on a fresh Retropie install on a 3B or 3B+ using the 4.6 official image (Or 4.5.1 updated to 4.6). Anything you overwrite is your own fault at this point!
RGB: For RetroTINK Ultimate, Pi2SCART, RGB-Pi, or VGA666 to a 15khz Display
Install Retropie and configure your desired content
Connect to WiFi or Ethernet with internet access
Download the CRTPi-RGB.zip into your root folder (cd /) with the command "sudo wget https://github.com/crtpi/CRTPi-RGB/raw/master/CRTPi-RGB.zip"
***WARNING: THE NEXT STEP WILL OVERWRITE GAMELIST.XML FILES AS SHOWN IN THE REPRO! BACK UP ACCORDINGLY!!***
Unzip and overwrite files with the command "sudo unzip -o -q CRTPi-RGB.zip"
Remove the zip with the command "sudo rm CRTPi-RGB.zip"
Power off the Pi with the command "sudo poweroff" and remove power once the green light stops blinking
Put SD card in PC and edit /boot/config.txt to uncomment the appropriate block for your GPIO device AND comment out all other device blocks
Install GPIO hat with RGB output (RetroTINK Ultimate, VGA666, Pi2SCART, RGB-Pi, etc.)
Put SD card back in Pi and power on while connected to your output device
Drop to the command line or connect via SSH
Restore read/write access to the files you have overwritten with the command "sudo chmod a+rw -R /opt/retropie/configs/"
Restore execute access to the runcommand scripts with the command "sudo chmod a+rwx /opt/retropie/configs/all/*.sh"
Launch into RetroPie-Setup with the command "sudo ~/RetroPie-Setup/retropie_setup.sh"
Go to "Configuration/Tools > resetromdirs" and run it
Choose "Perform Reboot" from the menu to reboot your Pi.
OPTIONAL: RGB JAMMA Config Pack
Download the CRTPi-RGB_JAMMA-Pack.zip into your root folder (cd /) with the command "sudo wget https://github.com/crtpi/CRTPi-Project/raw/master/CRTPi-RGB_JAMMA-Pack.zip"
Unzip and overwrite files with the command "sudo unzip -o -q CRTPi-RGB_JAMMA-Pack.zip"
Remove the zip with the command "sudo rm CRTPi-RGB_JAMMA-Pack.zip"
Restore read/write access to the files you have overwritten with the command "sudo chmod a+rw /etc/pikeyd165.conf && sudo chmod a+rwx /opt/retropie/configs/all/autostart.sh && sudo chmod a+rw /usr/local/bin/pikeyd165 && sudo chmod a+rw /usr/local/bin/mme4crt"
Reboot the system with the command "sudo reboot now"
The RGB fork is now utilizing Snap-Shader, plus a newly-enhanced runcommand-onstart script, with provision for user-specified per-game configuration!
Here's the new script:
https://github.com/crtpi/CRTPi-RGB/blob/master/runcommand-onstart-NEW.sh
Here's information about Snap-Shader:
https://github.com/ektgit/snap-shader-240p
And here's a quick rundown on how it works:
Not only does the new script carry forward the per-core scripting for 2048x / 1920x / and 1600x resolutions -- but adds per-game scripting by adding a text file to the system config and naming the rom(s) within the file. This allows you to force 2048x on a system that defaults to 1920x, or the other way around. This is especially useful for PSX, FDS, PCE/PCE-CD, and MAME for the few games that are 256 or 512 wide. Below are some example config files:
/opt/retropie/conifgs/psx/256.txt
Brave Prove
Castlevania - Symphony of the Night
Crash Bandicoot
Final Fantasy Origins
Final Fantasy Tactics
/opt/retropie/conifgs/megadrive/256.txt
Bubble And Squeak
Bubsy in - Claws Encounters of the Furred Kind
Bugs Bunny in Double Trouble
Caesars Palace
Captain America and the Avengers
/opt/retropie/conifgs/fds/320.txt
Akumajou Dracula
Donkey Kong
Otocky
Super Mario Brothers 2
You get the jist. It doesn't need an extension, but should match the rom name including punctuation. This forces them to launch in 2048x240p instead of the default 1920x240p, or vise versa. This gives the end user full control on a game-per-game basis over the horizontal integer. You'll still need to write a retroarch game config to override the defaults there, but this at least gets you the right field. For games with odd/shifting vertical resolutions (like Chrono Cross, Battle Arena Toshinden, Castlevania SotN, etc.), a single pass of snap-shader is applied (snap-basic, nearest neighbor filtering, and "don't care" scale).
Final Thoughts:
If you have any questions, comments, concerns, or issues -- please PM me or DM me on Reddit or post on one of the threads. Chances are, it's a "feature" not a "bug." :)
