Sega Rally 2 - Model 3 - RPi 5 - Perfect Performance!!

Making use of Supermodel3's FPS monitoring facility to see how well the Pi 5 is running the Model 3 games. This time it's Sega Rally 2!

The native resolution of most, if not all, Model 3 games is 496x384. I've made sure that Supermodel3 is running at that resolution as higher resolutions can majorly impact the performance, and maintained the original Model 3 aspect ratio of 31:24.

My Raspberry Pi 5 is overclocked to 2750/950 which I've found to be quite stable as long as there's a fan to provide cooling. The Pi is running the Bookworm 64-bit Lite OS, with RetroPie installed on top. If it's important, I'm using a 8BitDo SN30 Pro to play this game.

Make sure your ROM is a non-merged parent ROM, not a clone, of the game. I explain in the video how to identify if your ROM is merged, if Supermodel is running a clone and how to remove clones from a merged ROM.

Installing Supermodel
-----------------------------------
If you want to install DirtBagXon's fork of Supermodel, go to his GitHub at https://github.com/DirtBagXon/model3e... and copy the "wget" command to download the setup package onto your Pi, then you can install it in the same way as any other emulator from the Experimental section of RetroPie-Setup. Look for "supermodel3".

Using the FPS Monitor
------------------------------------
- If you want to enable the FPS monitor then you need to add a parameter to the emulator's command line.
- Open up the file "/opt/retropie/configs/arcade/emulators.cfg" in a text editor, find the line that begins "supermodel3" and add "-show-fps" to the command line before %ROM%.
- Mine looks something like this:
supermodel3 = "XINIT:/opt/retropie/emulators/supermodel3/supermodel3 -borders=1 -show-fps %ROM%"
- Or you could conceivably duplicate the line and give it a slightly different name so you have one that monitors the framerate and one that doesn't.

- To monitor the framerate you need to access the Pi's command line remotely via SSH using something like PuTTY.
- Launch the game as normal, then from the terminal type: "tail -f /dev/shm/runcommand.log"
- This will then start printing the contents of the log to the terminal window and each time a new line is added to the file, that new line is displayed in the terminal. It updates approximately every second.
- When you want to stop monitoring hit "ctrl+c".
