>>43968508Ignore this retard, he has no idea what he's talking about. I bought an emerald cartridge earlier this month and replaced the battery with zero soldering experience and was ezpz
>You need to reconfigure the game's internal clock manuallyYou literally just replace the battery, set the clock in your starter house, and you're good to go. FRLG doesn't even have an internal clock at all, it's just for RSE.
>Even if you did all of that you have to start a new game for everything to work properly again.This is true for RBY/GSC, but not for RSE. On GBA carts, the save data is on the SRAM, not the cr1616. I thought the same thing as you until I did it myself just this past week, and I still had my save data after replacing the battery.
