The STM32 line of microcontrollers – usually seen in the form of an ST Discovery dev board – are amazingly powerful and very popular micros seen in projects with some very hefty process… ...

Using the ESP8266 module, wirelessly upload sketches to STM32 MCUs via the Arduino IDE. Supported Devices: STM32F03xF/K/C/, F103C8/B (including Blue Pill and Black Pill), F103VCT, F107RCT. ESP8266 Pin ...

cmake/ (symlink to the cmake subfolder of arduino-cmake-stm32, or just copy it) Change the cmakelists.txt and use paths you noted before (toolchain & arduino STM32 file in the example) e.g.

Logic levels are an issue, as the STM32 uses 3.3V logic while the Game Boy is a 5V device. ... and they can be programmed by a less tech-person in arduino IDE. Even without wifi, ...
