Basic Assembly and Setup

Hello community! I'm a computer science teacher about to hold a two-day session for my high school students using a collect of Byttle robots, and we're so excited! We're using the kits supplied by Petoi, and it's going to be a great event! There are a few advanced robotics students that immediately wanted to know the software we'll be using, so I've been toying around with OpenCat to see if it's usable with other four-limbed robots and non-Nyboards.

I'm hoping someone might be able to point me in the right direction for how to best/easiest customize OpenCat to work with an Arduino nano compatible board. I'm able to load the software just fine, but the Serial Manager loops on the question for resetting joints, and I receive two prompts to change my model and board settings and a second prompt to set EPPROM. I'm new to robotics, so I'm not sure what these mean. In OpenCat.ino, I set the board to the latest version for NyBoard by uncommenting the line. Should I be setting something different since I'm not technically using a NyBoard? And the model I selected was Nyblle since it's closest to what I'm trying to do. I've scoured the documentation and online, and I'd appreciate any tips or resources folks might have! Thank you!
