GBaccelerator GB FAQ

The contrast and refresh rate of the LCD in the Game Boy is affected by the clock speed of the entire system. You can compensate for these changes in lightness by adjusting the contrast pot on the side of the Game Boy.

Unfortunately, no. Because of the way the original Game Boy reads buttons, the GBAccelerator must look for specific timings on a specific combination of button lines.

Unfortunately, no. Because of the way the original Game Boy reads buttons, it takes all 3 button wires to read the status of only 2 buttons. Therefore, there aren't enough buttons available for Select, Up, and Down.

Using Fast speed, the Game Boy will run at about 1.5x normal speed. Using Ultra speed mode, the GB will run at about 2x normal speed. Using Slow-Motion speed, the GC will run at about 0.66x normal GBC speed.

GBAccelerator GB can be installed in the original Game Boy (DMG) or the Game Boy Pocket.

Steady=normal speed, single-blink=fast, double-blink=ultra, and fading in/out=slow-motion. Note: these codes do not apply when using wireless (if equipped) since that also causes the power LED to blink.

No. Overclocking a Nintendo handheld isn't like overclocking a computer. The electronics will generate a tiny bit of extra heat, but not enough to notice or cause concern.  The CPUs in these handhelds are often designed to run faster than they are running in these game systems anyway.
Probably a little bit, however we've run GBAccelerated systems for the whole life of a set of batteries and can confirm that any decrease in life is very small and should not be a concern.
No. We've done extensive testing with GBAccelerator at all of its different speeds and have left it running for hours on end with no signs of damage.  Many Nintendo handhelds are underclocked to begin with to save battery life.
