Thank you for the explanation. It'll be great if ems-qart can handle multi-rom. I noticed far below the limit of 64 Mo the ems-flasher complains about full cart when I transfert gbc roms. Around 4 Mo I can't send more... I don't know for classic .gb how many roms it can get before reaching the limit.
Anyway, for the ems-qart UI (which is great), it would make sense to have a smaller cart image, and add extra information below. Since there won't be like 60 roms in a cart (I guess), you could use scroll bars. Adding multiple roms could be also below the left image.
I've made a quick and dirty mockup:
Also by default on my system, the ems-qart window is quite huge (1050 px wide, 700 px high). I noticed also the images are probably in svg because if I make the window bigger, they can grow. So maybe the window could be more like 800x600 to fit on smaller screens (maybe it's the case, it depends on resolution?), or at least be able to reduce the size. Maybe it's also this size because my fonts are quite big. In this case, the "bank x Bank 1 [] bank 2" field could maybe wrap in the line below (even if it would look less nice this way)
