At the moment the speedrun page for Roombo: First Blood has Switch and PC. It is also on PlayStation and Xbox. I have been playing the game lately on PlayStation and found some glitches I want to use in a run. However, I do not know if any runs I make on PlayStation would be accepted because there is no option to select PlayStation (also Xbox) when submitting a run.

I'm not sure if you've already seen that, but it looks like those platforms are added as an option now.
