i love

somebody correct me if i'm wrong.....

but the pocket and color both have internal 5V.  if not coming directly off the power supply or anywhere else (preferentially), then check on pin 1 of the cartridge connector (or, is it pin 32???). 

either the first or the last one, should be 5V (and the other will be GND).

edit -- i realized that this answer may not make sense.....  becuase obviously how is there 5V with not even that voltage from the battery source???

well.  the power supply converts the incoming voltage into what the circuitry needs, so, in the DMG's case, this means taking the 6V and giving you +5V and -18V (for LCD contrast). 

and, unless i'm nuts, the pocket power supply gives the same.  the pocket i'm not sure about the contrast for LCD, but the 5V should be a standard.

thanks guys (:  constructive criticism helps a lot, as some things folks mentioned have already been implemented.  the choice to go with a single LED was a call after i had a dual version made up as well (well, a few versions, different thicknesses, single/dual LEDs, etc...).  its really just a matter of balancing things that i like about what is on the market, with things i (personally) thought were rather strange design features.  but, yeah, to each their own i suppose.  but, the feedback does help tons.  i mean, i've just got to keep in mind the reality that it is really just a backlight...  and at some point chasing after the perfect one gets kind of ridiculous.  the design could be redone for ages honestly...  and will be changed more like it should.  i would imagine there will never be a final version.  and, there shouldn't be i guess, as there is always something to improve upon...

so, yeah, i hope the vid helps people that have asked.

its booting into menu 2, which is where i put muddyGB (to test the powercycling before shipping).  it typically means that you are turning the gameboy on too recently after turning it off (the powercycling bit).  the manual EMS did i think says to wait a second, but in reality its closer to 5-10.  and, slip the cartridge out of the gameboy if it doesn't work, as that seems to speed the cap up in its discharging (so that powercycling doesn't happen).

but, that is what is going on.  MuddyGB is the ROM in menu 2.  you'll notice the green light LED illuminates when muddyGB 'happens' as well.  this indicates you are in menu 2.

you did nothing wrong.  you've (i suppose) stumbled across one of its features.

PS - don't connect the cart via USB when the cart is inside the gameboy, especially if the gameboy is powered on.  take the cart out.  (:

the PCB fabhouse will do that.  you don't assign colors in CAD design.  you tell your fab house what you want...  say, green soldermask with white print, or white soldermask with black print

yup

from the first picture.

the lighting is just bad in that pic though.  all the pics are of the same looking unit.

unless i'm missing something...
