GameCube Question

[Atari6600]

So I recently learned that Nintendo...in all their infinite wisdom...used a battery akin to the cell batteries in old SNES and Game Boy cartridges. 

Now, I don't have the tools or know-how to replace it and the nearest retro game store that could do it is allegedly an hour and a half away from me.  And if it's no longer in business, then the nearest one is upwards of three hours away from several counties over.  So I'm hoping I can just deal with adjusting the date and time every time I use the system.

My question is will this have any negative effects on the following GameCube games, which are the only ones I own:

Custom Robo
Mario Kart: Double Dash
Mario Party 4
Mario Party 5
Mario Party 6
Mario Party 7
Sonic Adventure DX
Sonic Adventure 2: Battle
Sonic Gems Collection
Sonic Mega Collection Plus

Also, will the dead battery have any negative effects on raising Chao in the Adventure games?  I'm hoping all of these games will play with no issue, but I swear I recall hearing that Chao raising has real time elements tied to it.

AFAIK it is much like the Saturn; annoying but not game breaking for anything I've heard.  Dunno about the specific games though :/

The battery (typically CR2032) is used to keep datetime for the console. AFAIK, most consoles with datetime have one (aside from handhelds like Switch/2 which are pulling from the internal battery). I also vaguely recall Sony issuing a console-level patch for PS4 within the past few years to address boot issues when that battery dies.

The battery is soldered, so you'd need some tools to replace it. It's a very simple job, so if you know or can find someone with a soldering iron it'd be a very quick job.

All that being said, you can manually set the clock in the GameCube's menu, so I don't believe it would be an issue with Chao raising unless you forget to change the time when you reboot the console.

It's annoying on the Saturn because all your saves die on the console when the battery dies.
