Game cartridges that use battery-backed SRAM have a power management chip on the board that switches the game to take power from the cartridge bus to power the SRAM chip instead of using the battery. Once the game is turned off, it switches to taking power from the battery again.
This means that the more you play an older game with battery-backed saving, the less you are depleting the internal battery that is keeping the save files alive! A game that you played/play a LOT most likely has much more charge left in its battery.
This is also why NES/SNES and other carts with save data (GB/C + a few GBA/N64 games with SRAM, etc) suggest that you shouldn't rapidly power off/on the console with the cart inserted--this switch may not happen cleanly if you rapidly turn the console on and off, which could cause the SRAM to not be receiving power when it needs it for a minute, causing corruption as some of the SRAM's bits get zeroed.
Actually the most interesting thing about @unboundgravel for me ist not the race itself nor overprised Emporia or people getting emptied their wallets and their bikes turned to shreds in the ubiquitous peanut butter mud...
... but the fact it acts as an event for spotting new and unreleased stuff!
Like, lo and behold, a 1x 13 speed Sram red AXS Transmission (?)
Saw someone say that the more save games you have on a battery-backed cartridge the faster the battery will deplete and I honestly can't tell if they're trying to trick people into wiping their cherished 16-bit era game saves or genuinely believe that. Like, how is that even possible? Whether you're holding a specific flip-flop high or low, doesn't that take the same power? Why am I doubting myself? Intuitively it makes no difference, does it? What the hell? #SRAM#RetroGaming
