Create me a multi-cart that will work on my wonderswan and wonderswan color
No project changes were made; the current project is still an empty USB‑C Wi‑Fi/BLE temperature/humidity sensor design. Your new WonderSwan/WonderSwan Color multicart request remains unstarted because no ACUs are currently available; it will also need cartridge-interface specifications, storage capacity, bank-switching/FPGA architecture, voltage compatibility, and physical cartridge requirements defined before schematic and PCB work.
