@Davelusa yes P4 should be fine, I'm actually doing a Street Fighter cab conversion to an LED marquee and P4 is the best fit for that. Hit me up and I can send you some pics on how it turned out. Here also is a recent Bartop project I did https://www.instructables.com/id/Arcade-Machine-With-Changing-LED-Marquee/ . That one is PC based and has a nice feature unfortunately only available on the PC where the marquee will change also when scrolling through games and emulators on the front end.

@PatrickTee could you please send me your art? it was great. I don't know how to work in image editing programs 🤩🤩 pauloarquiteto@live.com
