Great! So happy to hear this! It really is such a simple fix. Unfortunately the Pocket simply can't stand that much power drain!

Thanks for the tip!  Both LSDJ and Nanoloop now work problem free!

Thanks for coming to the rescue Justin smile heart

Fixed!  Dug the 220 resistor out of my RGB backlight gameboy and the pocket works like a champ now!

@thursdaycustoms which wire do I solder the resistor to?

either, whichever is easiest with the way the case comes together and such.  you'll get the same effect either way

@thursdaycustoms its a green backlight.

Okay, those draw a TON of power. I bet the backlight is so bright it kind of washes out the LCD? I believe they were designed more for the DMG. Definitely try a 220ohm resistor and see how that works. Should be a perfect brightness and your LCD will likely not change contrast when running LSDJ. Let me know if it works!

You need to add a resistor to the backlight to bring the brightness down and therefor draw less power. I have to do this with every Pocket that I backlight. I would recommend somewhere between 100ohms and 220ohms depending on the color of your backlight.
But as an experiment you can try desoldering the backlight altogether and try running LSDJ again. This will tell you without a doubt if your backlight is drawing too much power. I would recommend starting at 150ohms and then seeing which way you need to go from there.

I appreciate you pointing this out.  I somehow overlooked this, and just got used to my scrambled logo/"hello" with my dual clock DMGs.

Things like crashes and a corrupted logo can be caused by bad contact. Eg, dirt, misaligned cartridge connector and perhaps easy to overlook, that the cartridge/cartridge connector is slightly bent from internal pressure from a backlight panel or other mod, which might also cause bad contact.

The "dark screen" problem on the other hand is never caused by bad cartridge slot contact.That is purely an electrical problem, caused by varying power consumption when the CPU is power save mode. When the CPU's power consumption goes varies, so does the LCD voltage. There's not really a way to completely fix that without redesigning the power supply circuit. The easiest way to fix the dark screen problem is probably to edit the LSDj ROM, like I said above.

I think the Nanoloop problem is a bad contact problem, and you may have luck not inserting the card-tridge (haha) fully and see if that makes a difference. You might also want to try to burn the version of the ROM that doesn't have the custom "hello" logo.

got a can of compressed air perhaps?  clean out the edge connector inside the gameboy really well if so.  if you don't, try the tried-but-true 'blowing method'.  just like getting NES games to work...

you can usually just visually inspect the fingers on the cartridge itself, if you are up for it try a little bit of rubbing alcohol on them (although, if they work on other consoles its most likely not them)

you will hopefully dislodge something if its there, but also the moisture in your breath helps encourage contact between the console and cart a little bit.  this isn't suitable as an all-the-time solution, but it might at least help diagnose the issue as poor contact.
