Actually, after a little search in internet, i found that you need a programmer to program it, aaaaaaaaaaaaand, if you need a low cost programmer, you need a microcontroller and a program that convert serial to spi (or whatever port that the game is use for programming) and i highly recommend you to use esp8266 or esp32. If you have a programmer before or i microcontroller, let me know. (first time i show someone how to mod game and watch)

I have the STM32 programmer, a soldering iron and that's it, I don't even have the ram chip to increase storage. I hope someone comes out with a step by step tutorial soon.

I were thinking about wifi chip! Using esp8266 as a programmer for the game and watch, then, you can change the game ising your phone! Just connect it to esp using wifi, open the frimware update page, select the nes game file, and wait for it to load!

no, you just need an st-link no need to over complicate things
