If you think that's bad, imagine an equivalently-accessorized Game Gear.

I think one of those attachments are actually for a 12V 70Ah car battery

Noticing it only after parsing the rest of the setup made me giggle a little bit.

Pretty sure that's the biggest watch I've seen

I had the GameBoy Color version of the magnifying glass/speaker/fake joystick combo. It ran the speakers and the light off of its own pair of batteries. The speakers were an upgrade (especially for the stereo sound) but everything else was a gimmick. The incandescent bulb was too dim and housing around the screen made it darker and even more difficult to see:

Later on in early 2000s we got the worm light. LED and was powered from the link cable port. It was considerably brighter and hardly affected battery life from what I remember:

We also eventually got magnifying glasses that didn't have the housing around the screen to darken it:

Yes.

no

About tree fiddy.

You’d have maybe 5 minutes before it’d suck the battery dry.

[EDIT]

Based on further research (read: exactly one DDG query) It appears the Action Replay is actually significantly more complex than I had guessed and functions differently enough from the Game Genie that they quite often simply cannot operate in tandem like this and can cause serious issues.

Read on if you'd like a cool story that has little to do with reality, or would like to imagine how chaining game genies might work if that was feasible :3

[/EDIT]

Based on my (admittedly not incredible) knowledge of how those devices both work, they intercept reads for specific memory addresses from the CPU and insert their own values. As long as they both weren't set up with codes to modify the same address very little would happen, it would behave as you might expect.

If the two both had codes that modified the same address the Game Genie would "win" here since it is physically closer to CPU in the chain. It would see the address matching one of its codes and spit back its value, neither the cartridge nor the Action Replay would see the memory read occur.

Can confirm. So far I've gotten an external monitor, keyboard, mouse, docking station and a stand for it so it can be used as a laptop as well while traveling.

It certainly has issues but it's an impressive device.

You've never sharked a genie? What a prude!

Filthy casual.

Remember when we all dressed like that 10 years ago?

Well yeah! My uncle works for Nintendo!
