License violations (a.k.a Naughty List)

All the schematics in this repository are licensed very liberally under CC BY 4.0, so you can copy, distribute, modify, or even sell them commercially if you want. There's just one requirement: attribution

Basically it just means this: don't remove the original creator's name, or at least somehow acknowledge them. Here's the full description about it in CC BY 4.0

Known license violations:

"MRjohnathon": They took my schematics and KiCad libraries, made some arbitrary changes (some of which are completely incorrect!), and published them without attribution. They also made a PCB design based on the schematics, which is perfectly fine, although the design seems to be at least partially based on kamicane's Super-DMG-01 (licensed under CC BY SA 4.0), without attribution. They added attribution after I complained.
RetroSix. They use screenshots of my GBA SP schematics in their wiki without attribution. A simple link to the original schematics would be enough, but there is no mention of the source of the schematics.

Don't be this meme!

Original Game Boy (DMG)

Mainboard (DMG-CPU-06)

Traced based on high-res scans by Alex a.k.a. ArcadeTV.

Components were identified by desoldering and measuring everything on a DMG-CPU-06 board.

Note: there are several versions of original Game Boy mainboards, and these schematics have accurate information only for DMG-CPU-06

LCD board (DMG-LCD-06)

Components were identified by desoldering and measuring everything on a DMG-LCD-06 board.

Note: there are several versions of original Game Boy LCD boards, and these schematics have accurate information only for DMG-LCD-06

DC/DC power board (DC CONV DMG / DC CONV2 DMG)

Components were identified by desoldering and measuring everything on one board of each type (A/B/C/D).

There are several versions of the regulator board, but the board label is not enough to distinguish the different versions. gbhwdb uses unofficial type A1/A2/A3/B/C/D designation, which is also used here. Identify your board by looking at the following board version comparison photo:

Known differences:

A1 vs A2 vs A3: one trace is laid out slightly differently at the bottom of the board
A vs B: exactly the same circuit, but the board layout has been redone and small components now come in MicroMELF packages (vs 0603 imperial)
B vs C: almost exactly the same circuit, but the input filter no longer has an inductor, and many component values have been slightly changed. Schottky diode switched from surface-mount SOT-23 package to through-hole DO-34.
C vs D: main circuit and components are identical, but an extra undervoltage lockout (UVLO) circuit has been added and board layout has been redone once again
