is this supported on chrome OS?

xRC Sim officially supports Windows, macOS, and Linux. ChromeOS makes it a little bit more challenging to install third-party apps on, but it is possible to install Linux apps on ChromeOS… although it may require a little bit of tinkering around in the terminal. I recommend searching for a tutorial online if you can’t borrow another computer to use.


That looks awesome! I can’t wait to come.

Can you either post a screenshot of what you mean, or join the xRC Discord for support? We have plenty of players that have been playing the sim without issue, so hopefully we can get this issue solved for you.


How can we create our own robots?


I can’t find the option to.


I’m pretty sure you can only use the presets.

There is currently no feature to create your own robot models, but you can select between the robot model presets under Settings > Robot. This simulation is focused more on the gameplay side rather than the robot design side.


nice job on making this

I love it!


This is pretty awesome, I’ll definitely have to look into it.


Quick note. Is it possible to use the V5 controller with a PC? look here for a tutorial for using the V5 controller with this simulator.


Please make a backup if you choose to do this (Messing up with RegEdit can permanently damage your computer)


Good point. As long as you don’t accidentally delete random stuff you should be fine. But yes don’t go messing with RegEdit unless you are 100% sure you know what is going to happen (in this case you do) and you have a back up.

On Sunday, May 31, we will be holding our second SVC event: the Double Elimination Bracket Tournament!

How does this event structure work? Basically, you will enter the tournament as a team of 2, either of your own mutual choosing or individually to be randomly paired up with other individual players. The teams will be randomly seeded to fill out as large of a bracket as we are able to create, and played out until we have a winner. It’s double elimination. All matches are best of 1, however it is double elimination so if you lose a match you can still win the event from the losers bracket. The full event should run for approximately 2-3 hours, but once you are eliminated you will not have to stay

The tournament starts at 3:00pm ET / 12:00pm PT.

(If you have a partner already worked out, only one of you needs to submit the form. Do not submit a team unless both members have mutually agreed on the team.)

Be sure to join the xRC Sim Discord server if you plan to participate!


We are pleased to announce a Double Elimination Bracket Tournament this Sunday (6/7) at 3pm Eastern!

Participants can enter as a team of 2 or sign up to be randomly paired with another individual user.
Event will be streamed on FUN!

Same rules as SVC Double Elim Event #1, however if you have won an SVC Double Elim Bracket in the past, you may not sign up with the same partner you won said event with.
