you can run a bunch before power draw issues arise even off of standard dmg reg board. You ever seen Nex's megatron?
Run a bunch of what? You keep saying things like "bunch" and "fully-modded" but these phrases mean nothing at all. There is no threshold of LEDs or knobs that once achieved warrants something as "fully-" anything, pal.
Yeah, I have seen it. There are only two things drawing power that weren't in the original regulator calculations! The only thing the damn thing has that is special is the size. 6 LEDs, an LTC and a Atmel328. None of the other mods draw any power; not the dual pro sound, not the expanded cart slot and he never did share a video of the powering a keyboard while the LTC ran and the arduinoBoy was powered up.
Besides, he used a clear gameboy which indefinitely had the newest power regulator board with the largest capacitors and lowest bleeder voltage. Combined with proper resistance values on the LEDs and power connections to the LTC and Atmel which are designed to draw a static value of power, NeX has nothing to worry about.
Your basically saying that I can build a computer with quad SLI GPU's and pop in a 150W PSU and run with it.
If SuperQuinn has a gameboy with dried up caps, failing resistors and continues to add more load on the regulator, then yes the software will be affected.

power draw etc should not really crash the software.
Power draw can most certainly crash the software of any system. How can you begin to claim otherwise?

It's from 1990, if I recall correctly. (it's what was printed on the back of the LCD board). I had been noticing that a corner of the gameboy was warmer than other parts, but it was subtle enough that I always assumed it was just the warmth from the palm of my hand. (the pointed bottom corner, opposite the speaker.) My other dmg is '91, so i could just unsolder the prosound cables from this one and move the whole front screen -cover and all- and stick it on the base of the 'newer' one. Switch halves, basically. Would a year's difference matter?
As for the backlight, I'm using nonfinite's v5 backlight. There's no tutorial at present for that model, but it seemed straightforward enough to install.
I'll try for a resistor as you suggest. I have 220, 1k, and 10k. The page for the v5 says the resistor is already installed though.
Try adding the 220 to one of the wires. It will be a little more dim, but this is my suspicion as to the crashing.

I had this Happen with a pocket. Games worked fine in it but LSDJ caused dimming and crashing. All I had to do was solder a resistor in and it's worked like a charm ever since.
In this case, I doubt it was the software. It was most certainly the cartridge. What cart was LSDj playing from?

Re: DMG backlight dimming and cart crashes... any correlation? (24 replies, posted in Nintendo Handhelds)
The mainboard pin is the very closest point to said regulated source, but there are filter capacitors throughout, so it is all regulated as far as I am concerned. Is this a backlight with a built in resitor, or external? It may be a good idea to increase the resistance value. It may also be a good idea to replace some of the electrolytic caps as well. What CPU version is in there? I am not so much concerned with the CPU itself, but the revision of the power regulator in the bottom corner; the older ones are not as good as the newer ones which contained much larger caps.

That's what I was thinking, but It still wouldn't explain why the dmg can only load certain carts and not others. My reasoning is if there's a problem there, then it most likely extends to all other carts but in different degrees. e.g. Tetris works fine, but that may be because it's such a simple game. LSDJ works (mostly) because the cart is made more robust than the original commercial ones (?). I'm thinking that the backlight draws power from the unregulated source and causes a large enough change in current to 'confuse' the processor and the program, throwing it out of sync and crashing it. (I'm going out on a limb there, I don't know much about how the internals work).
That is basically correct. Certain opcodes do require more power, especially related to the sound. This can easily cause it to crash if you're starting out with less!
Which "unregulated power source" are you connecting it to? The battery terminals!? The best places are for you to connect it to the capacitor below the screen or to the power LED voltage, prior to the resistor of course. These are both regulated power sources. You should not have to lengthen the wire.

I am also debating about switching to unity gain buffers for the discrete outputs as I found them to be rather hot and it's likely not necessary to amplify the audio as it is already near line-level (I need to verify that).
I am mulling over a similar conundrum with one of my own designs. Think about what you are making; a noise filtered line-out? An amplifier? A mixer? All three? Anyone composing with their NES should be responsible enough to have an external mixer and amp, so just by going with a clean buffered connection sounds good to me. 
Isolate it, filter it, mix them, buffer it and you'll have a sale.
