DMG PCB codes follow the following convention:

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?
