I'll make a little board you can drop in, wire to the appropreate points and BAM! Wonder if there would be room on the back of the powersupply. 2 birds with 1 stone.

I don't think I'm quite savy enough to set it up to be controlled by the gamepad just yet haha. I've only been modding gameboys for a little over a month.

The installation instructions have it on the top of the front half of the case opposite of the cartridge slot. You could probably put it just about anywhere it'll fit though.

Might pick up one of his RGB backlights and have a play. I reckon having its colour controlled via the gamepad at startup will be a winner!

Where does the pot sit?

Kitsch sells an RGB backlight that goes with the start/select buttons and a 3 knob controller that let's you change the colors on both. I'd already bought a HHL pink backlight though so I just set it up to match my backlight.

They look pretty cool! I might rig up a keypad controlled RGB LED. See how it turns out

I hadn't gotten my EMS cartridge yet so I'm sort of kicking myself for adding something else that draws extra power but now that they're in there I'm too in love with how they look to get rid of them loll.

If you were super keen, you could drop in a small AVR that will interrogate the keypad at turn on, You could select RGB colours like you do paletes on a gbc!

I got them from Kitsch's shop. They're RGB, so depending on how you hook them up I think there's something like 7 different color combinations.

Whaaaaaaaaaaaaaaaaaaaaat! backlit buttons!?!? Link me?

Well I've got backlit start and select buttons also which probably just makes the whole issue worse. My gameboy also has the older style regulator that only has a single cap instead of three. That may be part of the issue as well.

Yeah, they're all pretty power hungry. Never had that probelm with my carts though. Older CPLD's/FPGA's use a fair bit of current. Newer ones can shut down logic blocks that aren't being used.

I already swapped all the caps in the entire gameboy. It was one of the first things I did when I started having this issue. The contrast problems only happen when I'm using the EMS cartridge. It seems to draw more power than the official game cartridges. I've heard of people with backlights having contrast problems with the EMS and the Ever drive cartridges because they use more power. At least that seems to be the consensus.

Good to hear it sorted out a few issues. Keep us posted on the pro's and con's of your mod.

If contrast is flickering, may be a good time to swap out the caps on the reg board.
