Looks nice.
But imho Amiga is not a perfect arcade machine.
A lot of the classic Amiga games were designed for one button joysticks.
So e.g. jump is performed with diagonal joystick movement instead of a second button.
As a kid when I was an Amiga owner in the end of the 80s I didn't care.
But today this feels odd compared to playing jump & run games in MAME, Sega or Nintendo
i totally agree with you that Amiga is not a perfect arcade machine. and A lot of the classic Amiga games were designed for one button joysticks!
BUT and its big but for me. first of all The Amiga was very important to me in my life. its help me to get a job as animator back in the days. and yes i really fun join to play the games on the amiga.
in the past the Amiga was the best computer in the world from all aspect! so i decided to build an arcade machine only for the amiga....after i build almost any kind of arcade that you want. look here
