So, I've found an old radio shaped like an old 90's computer, and I've noticed that the base has a perfect size for a raspberry pi 3b+, it has 90mmx95mmx30mm, and the screen there could fit exactly a 3.5" 4:3 aspect ratio LCD screen. I wanna make it like an "mini pc" with the PI OS to run retropi, dosbox, etc. I've never really touched a PI before, but the real issue is that I just can't find a raspberry pi screen thats 4:3 and has 3.5". I've found one thats 2.8" 4:3 (even it is 640x480) but thats way too small and I kinda wanna fill the whole speaker grill there. And aslo don't want a 3.5" 16:9 because it would make a black border both up down and left right, since most games will be 4:3
Do you guys know any LCD model to adapt to it and how to, or even if there is one made for a PI already in those dimensions?
