How Many Controllers RetroPie can Handle?

[natti89]

Good morning

I have a RPI4B running in a self modded 4 player TMNT arcade1up machine and I had a couple questions.

How many controllers will Retropie keep stored in configuration?

I have the 4players controller divided up into 2 XIN MO controllers (so I have a total of 4 controllers running off of the two USB 3.0 ports on my pi) so I have a couple ports to spare.

What I'd like to do, is install 4 more USBs (2 of these.....https://www.amazon.ca/Ports-Female-Extension-Motorcycle-Dashboard/dp/B01N0XH0V2/ref=pd_sim_147_6/130-9682389-9953662?_encoding=UTF8&pd_rd_i=B01N0XH0V2&pd_rd_r=acf360b0-b1f3-43dd-aec9-25babba4a03d&pd_rd_w=vCXo2&pd_rd_wg=lp6Nm&pf_rd_p=35ed9a42-e80c-45ce-9dbe-bfe036191a8a&pf_rd_r=HWC0YEAFB80HPF7EWYKK&psc=1&refRID=HWC0YEAFB80HPF7EWYKK) so I have the choice of using the arcade stick or a PS4 controller.

So.....

Can I add a USB hub and then 4 more controllers in my setup, or will I mess up my arcade configuration?

Thanks much.

UPDATE: I managed to scrounge a cheap USB hub and will be trying this out....I will post results when I'm done.
