@DIY.Engineering Thanks for getting back to me - I will reply to your email over the weekend. Appreciate it wasn't intentional - love your work. Cheers.

@hamak I think a thread about spinner controls is a good idea. I am not familiar with the games you mentioned, but I can add some ideas and discussion points:

Arcade games with spinners and trackballs work best in AdvanceMAME in my opinion, simply because you have complete control over the devices using the config file and sensitivity/speed adjustments can be made using the MAME GUI (and they get saved). I haven't had much luck in other versions of MAME. Atari 2600--Up until now, I hadn't given it much consideration, but I am curious if I can get spinners working for the Atari 2600. I am fairly certain I could make this work using AdvanceMAME (mess) but I'd like to get lr-Stella using spinners if possible.
