You will optionally need the a MEGA65 ROM file, if you wish to use BASIC65: https://files.mega65.org?id=54e69439-f25e-4124-8c78-22ea7ddc0f1c
If you do not have such a file, the MEGA65 contains the free and open-source OpenROM alternative.
The MEGA65 project maintains an automated build server at https://builder.mega65.org/
