This is a bit... dunno? There seems to be a 18 character name length limit for profiles (including spaces), resulting in actually severe limitations for displaying the full name of certain games (even, or especially) in the software.
Is this a hard limit on the mouse (z3) display side, or is it a way of minimising on-board memory usage? Anway, this seems very restrictive, given how many game titles go well beyond that - even disregarding additions like "special edition" or similar.
