Battery-backed save loss
Battery replacement

Battery and cap replacements on Super Metroid and Zelda, with saves backed up and restored throughout. Initially used tabbed batteries as a stopgap, then swapped to coin cell holders once they arrived.

Just doing some light maintenance on my game collection. Sadly I couldn't find my battery cell holders, so I used tabbed batteries. First up was Super Metroid with new battery and capacitor. Also, cleaning of the contacts. Saved/restored the save file. #RETROGAMING #SNES #Metroid

Next up was The Legend of Zelda, with new battery, new capacitors and cleaning of the contacts. Also saved and restored the existing save file. #RETROGAMING #NES #Famicom #TheLegendOfZelda

Today we're righting wrongs, this has been on the back of my mind for a while. Now that I have coin cell holders again, I replaced the tabbed batteries. Which will be used for other purposes. #RETROGAMING #NES #SNES #Metroid #Zelda
