RGBCommander with Dual Ultimate I/O Boards in Multi-Mode

[matt8512]

I am a complete noob and I am in the process of building a 4 player arcade setup. I have so many LEDs that I needed 2 Ultimate I/O boards run in multi-mode. When I read the main page on the RGBCommander site, it says that there is an issue running RGBCommander with multiple boards in multi-mode. It says "The dual gamepad enabled UIO firmware breaks RGBcommander's ability to connect to the board. (Ultimarc Firmware 1.53 Multi-Mode)." Before I go any further with trying to install RGBCommander, does anyone know if this issue was fixed? RGBCommander seems super complicated to me. I am at the point where I'm thinking about scrapping my Raspberry Pi and just getting a mini PC so that I can use LEDBlinky. Someone please let me know if this multi-mode issue has been fixed with RGBCommander and please give me your thoughts on the Pi vs. the mini PC. Thanks in advance!
