== DMG PCB Naming Convention ==

DMG PCB codes follow the following convention:

 DMG[-?[?]]-???[?][(?)]-NN
      |      |      |    \-- PCB revision
      |      |      \------- optional code in parentheses
      |      \-------------- mandatory three or four-letter descriptor
      \--------------------- one or two-letter optional part

For example, DMG-BEAN-02 is a PCB made for
* MBC1A/MBC1B/MBC1B1 (without battery)
* 256kbit of ROM
* no SRAM
* ROM chip package is a narrow SOIC

=== PCB Revisions ===

Numbers include

*01
*02
*03
*10

Mostly minor routing differences if any. Sometimes additional components in 10. Never additional components in 0x?

=== Optional Parts ===

DMG-MC-SFCN-01 Momotarou Collection 2
DMG-M-PEAN-10 Taito Variety Pack

MC = Momotarou Collection? MultiCart?

Code in parentheses after descriptor is only ever K.

DMG-BEAN(K)-10 Xenon 2
DMG-DECN(K)-02 Mogurania (Mole Mania)


== CGB PCB Naming Convention ==

CGB PCB codes follow the following convention:

 DMG-?NN-NN
     |||  \-- PCB revision
     ||\----- PCB descriptor MBC
     |\------ PCB descriptor RAM/ROM size combination
     \------- PCB code

=== PCB Code ===

*A: Production Cartridges
*B: Test Cartridges
*Z: Revisions of certain A?? variants. Sometimes routing changes.

=== PCB Descriptor ===

Descriptors describe MBC and ROM/RAM size combinations only.

Maybe actually hierarchy? I.e. second figure is sub-index in first figure MBC PCB designs?

=== PCB Revisions ===

Numbers include

*01
*10

Never observed any major differences. Maybe minor solder mask differences?
