   getting close to v0.2 of this cart! changes include: open drain-compatible level shifter (should hopefully help w/a bunch of subtle bus contention problems); smaller footprint qspi flash; shorter battery clip and inset usb port (so it'll fit inside an unmodified cart shell, hopefully); and i added one more address line to both the parallel flash and sram (8MB flash is cheaper than 4MB, and 256KB sram is about the same price as 128KB... would be fairly easy to make this a multicart?!)
