Hardware > Rewired GB cart for external 5v to test with Game Boy Micro

Just some pictures of a hack I did. The pictures show a Donkey Kong Cart I rewired and a Game Genie adapter.

If it had actually worked, I would have wired it properly for a portable power source. Oh well at least I know for sure it's not only a voltage issue. This is why I asked the question before on what else could it be, because I had known the 5v thing wasn't working.

If someone could post the pictures in the thread, that would be nice.

What was the plan here? was in an atttempt to power the gba from usb through the cart? or something else?

Also the DK cart won't even work with Micro, it doesn't support GB/GFBC carts. you'd have to chip some of the plastic off, but then it wouldnt play anyway.

The plan was to see if it was just the voltage causing GB/GBC games not to work, which I found out was not the only reason for the GB/GBC not working in the Micro.
I didn't mention it in the first post, but I did modify the plastic of the DK cart in order for it to fit snug in the GBM.

Did the gameboy work when it was powered by the DK kart? or did you have to put the batteries in?

The Game Boy worked fine with the cart being powered externally. The Game Boy still runs off batteries, it's just the cart that runs off the external power source.

I heard from here that the GBA Micro and the DS/Lite don't support GB/GBC games because there is no switch that checks for an indentation to check whether it is a GBA game (indentation) or no indentation (for GBC).

The reason it doesn't work is because the GB-Micro and NDS doesn't have a z80 processor in it. But if you have a compact flash card it will run anyway because SuperCard has many emulators built-in. Maybe you could make a adapter for connecting it to emulation ROM connected to GB Micro and then it will run.

The GB Micro most likely DOES still have the Z80 in it, since it's able to crash into GBC mode.

To run a Game Boy Game Pak at 5.0 V, you need more than Vcc at 5.0 V. You need all 29 signal lines at 0.0 to 5.0 V too.
