Custom USB-C Charging Kit Pro mod for the Game Boy Color by Giltesa

This mod is not recommended for beginners as it requires quite a bit of soldering and shell modification.

The Game Boy Color USB-C Charging Kit PRO is the new circuit for Nintendo Game Boy Color. This time it is an all in one circuit and includes not only the charging controller but also a boost converter and audio amplifier.

The modern IPS displays with backlights require more energy than the stock display. Also, the flash cards to load tons of games consume the battery very fast. If you really want to enjoy the games, the best way to do it is using a rechargeable battery instead of AA batteries.

However, that is not enough because a higher power consumption is forcing the original electronic to strive more than it can. That may cause noise in the speaker or headphones.

Typical solution has been adding a charging circuit for the battery and a power converter to replace the old and not efficiently one which is included in the GBC. Some people also add an audio amplifier to hear better the speaker sound. All these things make the GBC perfect, however the installation require a lot of cables and can not be easy for some people without enough knowledge.

This board add all these features with a clean installation

1 frame board which includes the charging and light board.
