@Lord-Vek said in Trying to run Commodore plus/4:

What it would do if I wasn't the owner?

per the previous post:

Do check if /opt/retropie/configs/cplus4/ is owned by user pi (ls -l on that folder), else do as root: chown pi: cplus4.

@16bit as other stated already there is no need to use YAPE. However, from my experience some of the more recent homebrew games only work with YAPE. You may consider this guide [1] to install retroarch xplus4 and YAPE alongside.

@mth75 Hi. I don't mean to hijack the thread, but I really like your Plus 4 case idea. I'd love to know more about how you did it and what's running in it. I had been wanting to build another RetroPie unit (I have 3...a Sears Intellivision, an Intellivision Flashback, and a RetroFlag Megacase) but one with a bulit in keyboard. The plus 4 is perfect. Was going to use an old C64, but felt it wasn't as good. Do you have a write-up or any specs on how it all came together, including the keyboard interface you'd be willing to share? Thanks!

I read your question on the Which games ... with Wine/Box86 thread, let's start with this older topic.

Most importantly, I'm using the Keyrah (C= keyboard) interface (unavailable for a quite a while now) ...

The basics look like this:

not sure if you ever got an answer but i've been playing with this recently. change the SID emulation to the SID (fast) and then it goes like a rocket. if using a pi 1 or zero I'd also advise turning off the scanlines. I get 50fps on a pi zero with no sound issues. I get about 37fps with the scanlines and as you describe only a few fps with the default SID settings
