I've got two DMG's that may be suitable, I'll post pics later today.

I'll take a crack: The water park is supposed to be nice, but I couldn't go because I'm covered in tattoos and Japanese people don't like that.

This has been updated to be a total gameboy rom header utility. You can now adjust all of the header data to your heart's desire! It also supports uploading (patching) an existing rom.
Check it out, let me know what you think!

I see. Yeah the traces were cut originally when I didn't use the hhl board. I actually like the non destructive nature of the hhl board, especially considering its only a few dollars.

Oh by the way, here's the rom I was using to test with: https://archive.org/download/palette_202407/palette.gb
Fredrik Brundin made it for me, what a nice guy!

Yes. And also, if you don't also cut below the via, you're connecting an output to an output! The deadly sin. (At least potentially deadly to the chip outputs although it probably didn't cause permanent damage in this case.)
Wait how do you figure? It looks to me like that pad wasn't connected to anything.

Re: HELP: BIVERT MOD ONLY SHOWS TWO SHADES (20 replies, posted in Nintendo Handhelds)
My problem was the method I used to install the bivert. I cut the traces between the LCD connector and that little header thing, but in the wrong place. Here's how I cut it:
As you can see, I cut it ABOVE the via, not below. If you look at the back of the board you can see why this is a problem:
The yellow line is the trace coming off the via to the CPU pin. So the header pin I soldered the chip to wasn't contacting the CPU pin at all.
The vias on my board are not plugged like they are in that picture, so soldering a wire to the via didn't work. Instead I just soldered a peice of wire wrap from the cpu pin to the other side of the header pin, and voila! It worked perfectly.
Now time to go fix every other DMG I own....
As a side note, what the heck is the deal with this HHL bivert board needing the wire for ground? There's a ground on the LCD board right on the end with a huge blob you could easily bridge. What's the deal with that? Kind of makes me want to make my own bivert board with only a 2 gate chip. I really like the design of the HHL board otherwise.

Re: arduinoboy modes explanations/documentation? (28 replies, posted in Nintendo Handhelds)
Oh yeah, I was mistaken. I thought the capacitors next to the atmega was an ftdi header. The atmega is socketed though, so if you have an arduino with that same chip you should be able to pop it out and put it in the arduino to reprogram it. Or maybe you could just ask xiwi?

Re: arduinoboy modes explanations/documentation? (28 replies, posted in Nintendo Handhelds)
It looks like there is a header on the PCB for a programmer. You need a FTDI usb to serial adapter (you can get them on ebay for a few bucks) and then you will be able to program it. Or just get someone else to do it for you!

On a related note, how would I update my existing arduinoboy to the most recent code release? I have a midi-usb cable.
You need to plug it in via usb to your computer, then use the arduino IDE to upload the new code.
EDIT: Like not the midi cable, but the actual usb jack on the arduino (assuming it has one).
If you bought it from me, I have added some things (like for the PS/2 jack), so you'll want to use my build.

Images fixed. I tried to go off google photos instead of imgur since imgur is user hostile now.
Anyways, I figured it out! Though I'm kind of curious what you have to say jazz before I reveal the issue! I'll give you a hint: it had nothing to do with the HHL installation.

Topic: HELP: BIVERT MOD ONLY SHOWS TWO SHADES (20 replies, posted in Nintendo Handhelds)
I have done bivert mods on two gameboys and both of them have the same issue. Only two of the 4 shades of grey will display. I was just using some off the shelf hex inverter chip I had laying around, but I figured maybe that was causing the problem so I bought some of the hand held legend bivert boards and I get the exact same result. Also running my finger around the bivert board while it's booted causes graphical glitches. It seems like it's maybe a problem with some connections somewhere, but I'm not sure where to check. Any help would be appreciated!
Here's some pictures:
This is what I get:
Here's what it should look like (GBA SP):
Here is what it should look like (inverted, non biverted DMG):
