I am starting my project and I found this battery system on amazon :
https://www.amazon.fr/gp/product/B072J59RLZ
It looks far easier to use and cheaper


Do you think it is fine to use ?
I imagined cut the red cable from the battery to insert the switch button of the game boy and keep the switch button of this board alwways on "on" mode, do you think it is a good way too ?
And thanks all of you for this forum which is a gold mine (french expression maybe... means it is awesome
