Very nice and funny idea. If you work further on this, i would request the possibility to rotate the clock to make it compatible with the normal gba and the possibility to switch between analogue and digital design.
Thanks! I don't know if I will find the time and motivation to resume working on the GB version. But maybe I will do a GBA version because the hardware looks fun and easier to use. And it's even possible to develop GBA games in Rust, something I wanted to do.
