Sometimes Boys just wanna have fun…
I found my old GameBoy Color and a classic game: Pokémon Gold!
Problem: The save-feature no longer worked, when you played, saved, powerd the GameBoy off & on again, there was only the “new game” option, no “continue”.
Because of previous internet research I already knew what the problem was / what to do:
Step 1: locate my GameBoy-Cartridge-Screwdriver that I already made some time ago following this tutorial video.
Step 2: check the battery type & run to the local electronics store to pay way too much for one petty cell.
Step 3: remove old battery without completely damaging the board.
Step 4: almost kill the new cell by sucking at soldering but somehow manage to get it done anyway.
Step 5: hope, wish, plea.
Step 6: turn it on, press A a gazillion times to get through the introduction, save the game, turn it off.
Step 7: turn it on again & admire your work!
Now I only need to find time to actually play it… oh well…
