So off we go to the shops. Would we be getting a Commodore 64 or ZX Spectrum like my friends had? Nope. We were talked into getting a Commodore Plus/4. It had ten games with it, so seemed very good value.
Depsite none of my friends owning one, and scant little coverage in the Commodore magazines, I loved my Plus/4. It gave me my first experience of a Word Processor (albeit, a not very good one), had some awesome hidden-gem games, and I learnt to program BASIC on it.
So if you are in a similar boat to me and want to play Commodore 16 and Plus/4 games on your RetroPie then this tutorial is for you!
Warning: Fiddling about with things in RetroPie may break your set up. We advice you make a back-up of your SD card before doing anything we mention here. Although these instructions work with our set-up we cannot guarantee they will work with yours. We advice you to read all of this tutorial before commencing.
RetroPie does come with Plus/4 support, with the VICE emulator, but lumps it in with Commodore 64, and you’d need to edit each game individually to mark it as a Plus/4 game. That’s far too much faff. So, we’re going to set up a separate screen on our RetroPie for Commodore 16 and Plus/4 games.
So before we begin this tutorial, lets make sure you have what we need.
- A RetroPie system (A set up tutorial is here)
- A keyboard to plug into your RetroPie (for set up and for playing some games)
- A text editor
Setting up VICE
This is fairly straightforward. Go to Retropie Setup from within the RetroPie settings Menu.
Manage Optional Packages and from the list, choose
You can choose from a pre-compiled binary (quicker), or install from source (slower). We’ve gone for the pre-compiled binary.
Your screen will now fill with stuff like this for a bit, and then it will be installed!
On this screen, you can just select
back. Keep pressing
exits until you get back to the RetroPie menu.
RetroPie doesn’t come with the ability to set up YAPE via RetroPie’s menu, so we’ll have to do it manually. Quit EmulationStation, by pressing F4 and you will come to a screen like this:
type the following, pressing enter after each line, and waiting until you get the
$ prompt before typing the next one. You can also do this via SSH if you like.
git clone --depth 1 https://github.com/calmopyrin/yapesdl
sudo cp -r /home/pi/yapesdl /opt/retropie/emulators/yapesdl
The above code downloads Yape, compiles it, and moves the emulator to where RetroPie keeps its emulators.
Might be an idea to reboot the Pi after all this, so just type
sudo reboot and the Pi will restart.
Setting up a page for Plus/4 in the emulation station menus
To add a new page for the system in RetroPie, we need to access a file called
es_systems.cfg and access the themes directory. To do this we need to make a copy of these folders. We have a full tutorial for that here, if you have already copied these files, you won’t need to do it again.
configs > all > emulationstation and open
es_systems.cfg in a text editor. Paste in the following code, making sure that you are not pasting it in within another systems
this in this tutorial. If you need a logo to use for your Plus/4, this might be useful.
Making a ROMS folder for your Plus/4
Go to your ROMS section via SAMBA. Make a new folder called
plus4. You can also put your games in here while you are at it.
Tell RetroPie how to run a Plus/4 game
In a text editor, create a new file and paste the following:Code:
Save the file as
You need to make a new folder in the volume,
plus4and upload the above file to that.
Reboot your Pi, then you’re ready to go
When you open VICE you might find that it has a tiny screen! To remedy this, press
F12to go to the options menu
Video Settings, and select
Press Backspace to get back to the main Settings screen, go to
Settings Management, and choose
You can exit the Setttings section by pressing the escape key. The Setting screen is also where you can set up joysticks, and tell VICE which port you wish to use.
When we set up our Plus/4 config file, we made VICE our default emulator. If you wish to switch to YAPE, then you can do so by pressing a button on your keypad when you load a game to launch the Runcommand Menu, where you can change the default emulator for the system, or for just that game.
Ito switch your joystick port.
F8or Right Shoulder brings up the option screen, though you’ll need your
cursorkeys to navigate the menu
Sto remove display frequency
I can’t work out to remove the mouse pointer on screen sadly, so if anyone knows how then let me know!
