My understanding from watching various YT reviews of the Mega Drive Mini is that the Mega Pi is slightly smaller but more substantial feeling, so I imagine that would put the kibosh on the "Tower of Power" thing sadly. That said, I noticed that Retroflag recently brought out a nice addition to the SNES version which adds a (purely cosmetic) cartridge to it. I wonder if they're eyeing up the Tower of Power and considering it as a potential future product addition to their Mega Pi? Would be nice if so. God I love my Mega Pi. I give it a wee cuddle every day you know. It's nothing weird. Honest.

Thanks @mitu, my mistake here, I have used the script from Retroflag page, maybe a old script. This one, https://github.com/crcerror/retroflag-picase from the developer is working well. But I'll return to 4.4 anyway, 4.5 is showing the undervoltage message randomly, and SF3ii/iii is more slower even overclocked, 4.4 is ok to me. (RP2b, 3.0A)

Well... If it's hot outside it will still take the hot air in. If air goes out it needs to get in somewhere :) But i agree, i would use it in exhaust mode too.

So I got it to work. (In ES input) After I choose X as left shoulder and Z and right shoulder, I then had to assign the left and right bumpers on the controller as left trigger and right trigger. Before I was skipping these on the controller due to them being assigned to X and Z. All working fine now :)
