Thanks for the replies, but those won't fit in a gameboy.
3.5" is the limit, and i very specifically want 640x480.. though admittedly that's half my budget.
The one i linked, the control board is ok, but the position of the flex cable connector is really bad, i wouldn't fold back right. This one would be MUCH better, if i could figure out where to get it.

The website isn't in english and it's not one of those, click and buy sites, so i'm having trouble finding the right control board, But i'm pretty much set on the LCD module itself.
PD035VX2 is the only suitable 640x480, 3.5" LCD that i've found so far.
If anyone knows of any other 3.5" 640x480
LCDs, don't hold out on me.
Keep in mind, a lot of the rear view camera displays, say 640x480, but aren't.
Edit: if anyone knows what controller board is being used in the picture i just linked, that'd be nice, i'll get the controller board separate if it means it'll fit better.
Update: the controller board is SAGV2606 Still haven't found where to buy it, but it has a vga/hdmi/power daughter board, if i can find a way to bypass the daughter board and solder right to the controller board, it would work, it would be smaller, it would fold over properly, and would fit into a gameboy
My RPi needs a fan, heat will leech into the battery, so people saying I don't need a fan, don't understand how Li-Po batteries are affected by high temps. Cool pi = cool battery.
I would very much so like to see a Pi2/Pi3 Zero, power and size.
