    Default Strange Game Gear video and control problem related solely to cartridge (wrong colors

    I recently purchased a Tails Adventure cart. When the game boots, all pixels have an orange hue to them. Additionally, the game does not respond to button presses. Upon opening the cart, I believe I see some corrosion on the circuit. It looks piled up. I ran over it with isopropyl alcohol but it does not come off. The game still has the problems after cleaning with isopropyl alcohol.

    To be clear, yes, I have dialed up and down brightness and this does not change the color hue. Even so, it still wouldn't fix the non-responsive buttons.

    Has anyone ever encountered an issue like this? Does anyone have suggestions on fixing the problem?

    My guess is caps in the GG itself.

    I should have specified that I tested this on two different Game Gears and both exhibit the same problem and only with this one cartridge. All other games display and function correctly.

    The trace that connects pin 42 (pinout here) to ground has broken. Scrape off the corrosion with a razor blade and solder the trace to ground. Check the continuity with a multi-meter. Otherwise, you'll be stuck in Master System mode.

    Both of those look pretty gross on the PCB. Yuck.

    If the "mode" pin is not set correctly, the GG will boot the game in SMS compatibility mode and boy, that sure looks ODD. VERY ODD.

    Had that happen to me a couple times already when the cart connector was dirty.
    I'd like to share some wisdom:

    I'm not familiar with pinouts for Game Gear, nor am I that experienced with soldering and so I placed this project on hold. However, today I opened up a Batman & Robin cart and saw that someone soldered a cable from one of the pads, C1, on the board to pin 16 on the ROM.


    Is this what you meant?

    see how in ur batman and robin cart the traces connect to the 2 pin pads drawn in green? ur tails cart needs to have the same connection made again to ground them when the cart is inserted, so further down u need to scrape away the green protective layer to expose the bare traces and unfortunately u will need to solder a wire to create that same connection again just like the batman cart is.
