Midwest Embedded GBC LCD Test

MW Embedded backlit GBC LCD


Another backlit Game Boy Color LCD on the market, mainly in the USA and the time of checking he doesn’t ship internationally which is a shame. However, I got my hands on one through a friend in the states


Overall it's similar to the McWill and also the BennVenn, it does require some trimming and some soldering to install it into the shell. Also, it would suit a custom glass screen lens but the LCD metal board has been coloured black from the factory so it doesn't stand out too much. A good thing about it is that with the soldering you can get brightness adjustment so the test was done at max brightness.


One this that instantly jumps out at me about this mod is that the PCB seems to include its own power circuit for the chips and LCD. That is a good thing in as it won’t be demanding the power from the GBC just for the batteries. So the GBC can happily work as it is intended to


So I put it under the same tests as the other but only under the powered on tests as we know now that the games just add more strain onto things so we can predict that from the previous tests


Powered on



So what’s going on, well it’s also identical to the Mcwill in its consumption other than the fact the console will stay on longer all the way down to 1.9v which is good. Something is not quite right with it though


Towards the lower end of the voltage range strange things occur, the mod circuitry demands a huge spike, the LCD goes off but the console actually stays on. Why is this?


Hang on this might get a bit deep.


Behavior like this happens when the power circuitry inductors become over saturated with current, meaning that it can’t deal with anymore so the current just spikes fast and high. Luckily modern day IC chips just cut out when this happens and it’s also good that this power spike is only coming from the batteries, not the console itself so will not damage the console.


Overall it’s a nicely done thing and will run for around 4 hours ish and is on par with the Mcwill 5 hrs ish but BennVenns consumptions are still leaps above the rest.


Again this is still a great mod and nicely done and I’m sure it’s not the last we have seen for the GBC backlight world so when I find more I will stack them all up against each other

Great write up! Currently have two on order. Out of curiosity, what type of batteries are you testing with to determine run time? Thanks in advance.Mike

How large is the viewable area of the ME screen. I know it’s supposed to be similar to the BennVenn and McWill, but since you have all three, can you do a direct comparison? At that size every sliver counts.
