Oct 05, 2012 Original GameBoy DMG-01 Backlight. I actually prefer this to the GBC Frontlight below. It’s actually two mods – fitting an hex inverter, and fitting a backlight kit (from nonfinite electronics), I used the v3 version and it’s very easy to fit, I did need to clean the rear of the screen after removing the reflective film, that was the most difficult bit.

So you just installed a backlight to your GB Pocket and didn't destroy the LCD in the process? Congratulations! Converter arquivo dmg para iso. Your gameboy now has very short battery life, poor to no compatibility with flash carts, wild contrast variations in game, random losses of saved games.

This Gameboy has an i nternal pro sound mod which boosts the sound, making it louder, clearer and gives it more bass. Internal pro sound means that the headphone output is now the pro sound output. It has a nice glossy paint job and an yellow LED to match.

And the Everdrive/EMS/Derp/Smartboy/Elcheapo cart you just spent good money on doesn't work on your modded pocket? But *RandomUser* from reddit said his works perfectly!
Here's what you need to know, needed to know, and how to fix what could have been a very expensive learning experience!
Gameboys, Flash Carts and backlights have all been designed to operate at 5volts. The Pocket operates from 2 AAA batteries supplying anywhere from 3.2volts to 1.5v at the end of the batteries life.
A small circuit called a flyback converter is responsible for boosting the constantly varying battery voltage to a rock steady 5v for the CPU and cart, and -19volts for the LCD to make the pixels do their thing.
When you design a circuit like this, you must know the expected maximum and minimum current of the load. You then choose the inductor, the switching components, diodes and capacitance to give a satisfactory output with little ripple for the specified load.
15yrs later and along comes backlights and Flash carts. A typical flash cart will consume as much as the entire GB, more during flashing from an SD card. Backlights on average draw 15-50ma, this too is about 50% of the GB's consumption, and in conjunction will exceed the design specifications of the original converter.
So what do you do? You install a supplementary converter to generate a steady 5v from the battery supply. Is this hard? No. Here's how:
Above is an unmodified pocket running my V1.9 ElCheapoSD flash cart (not the low power mod version) These batteries are about 50% used, the 5V system voltage is now at 5.0volts, contrast is stable. During Flashing the contrast will flicker because of the high current draw. As the batteries get more depleted the contrast will vary more, the CPU will reset when you attempt to flash a game. Now lets add a backlight:

Excuse the 3' LCD, it is just being used as a backlight load on the system. The 5v has now dropped to 3.8volts. The contrast is adjusted to maximum for the image to be visible. The power supply is getting warm. Flashing drops the voltage to 3.7volts and after a few seconds the CPU resets and the image is no longer visible. It is important to note here that at 3.7volts, the cartridge is now using it's internal save battery to power the SRAM, at this rate the cell will last around 90minutes before it is completely flat, you save is lost forever and the battery will need replacing.
How do we fix this? We install the new converter.
This is a modified 101 backlight driver module from my store. The cutoff voltage for this module is 1.8volts which means it'll put out a steady 5volts all the way down to 1.8volts battery voltage. This is not ideal as NiMh cells will still have quite a bit of charge in them even beyond this point. THIS is what I'd recommend. I haven't tried this but according to the specs, it is what you want! It'll run until your batteries are completely discharged.
How to burn .dmg on windows 10. Depending on its output voltage, you may or may not need to cut the original 5v pin from the regulator to keep the LCD voltage alive. The first person to mod their pocket with the pololu module I'm sure will let me know.
With the module fitted, the system is at a steady 5v. There is zero contrast fluctuation with almost any flash cart. No random resets, no save game loss. You'll still only get 60-90minutes out of a fresh set of batteries but this can't be helped. There just isn't that much energy in a set of AAA batteries.
If you found this useful, head over to my FB page and leave a comment. I'll be making a few more of these about various GB subjects including backligting a DMG earlier than Rev 07, Backlighting a GB Color etc..

No cut traces! I will guide you through the steps required in cleanly de-soldering the FFC connector pins leaving the DMG unscathed.

Pins 15 and 16 on the FFC connector are the data lines from the CPU to the LCD, which we're going to proxy through the bi-vert chip.
Be warned: Please remove all batteries before continuing. It's also advised to do this outside of the DMG shell to avoid any accidental slip and melts.
The materials used in this instructable are relatively available online and easily substituted. I predominately use MG Chemicals products as their manufacturing and packaging facility is local. It is important to support your local businesses and I strive to support my local hobby, electronic, and surplus suppliers. My favourites are: A-1 Electronic Parts, Component Electronics, Sayal Electronics, and AA Electronics. For those products I can't source locally I use online distributors — for electrical components they're DigiKey or Mouser and for supplies they're Amazon, eBay, and AliExpress to name a few..

The solder station used is a Hakko FM-202 with a FM-2021 iron and T7-D12/D16 tip. It may be on the high end for a once in awhile mod but I'd recommend to keep an eye out for an equally mid to high end station from your local and online surplus or government auctions such as: govdeals.com and bidspotter.com (US/Canada), torontosurplus.com (My local place), etc. As an intermediate I'd recommend a Yihua 936 which is a sub $20 Hakko 936 look-a-like if you don't want to jump into a Hakko FX-888D.
