I got a couple of questions 1. Does it work and save 2.Is the internal battery functional And advice start it at 500 credits it will gradually increase My sapphire is already over 5000 credit
Yes. It's saving just fine. And to be completely honest, I am not sure what you mean by "internal battery", but, I testing all the Gameboy games I have listed on here, before I put them on here, and their save functions, and everything worked just fine on this game. Actually, it worked on all the games I have listed. Just not Pokémon Blue (Which is not on Listia). Hopefully that's a good enough answer for you. And in regards to your advice, this is my first time posting stuff, so I am inexperienced. So, thank you for the advice.
