my ti gameboy, I have no idea if it's

can you get an mspm0 with builtin usb the buttons are probably going to be hard to press but that might be ok/we can figure it out when they arrive do you have a screen selected? if not, maybe try to select a screen that could work, you might want a flex connector, check out buydisplay.com and maybe coordinate w/ Abse the boot/reset buttons are usually hidden or close the the mcu to avoid extra presses can't read the schematic
