 | | The sound generator (often called a PSG or Programmable Sound Generator) of the gameboy is embedded inside the CPU, and is sometimes referred to as an APU or PAPU, a 'Pseudo Audio Processing Unit' (Pseudo because it isn't actually a separate unit). |
 | | The original DMG gameboy's behavior is too strange for me to comprehend when used in the other, 2-step cases, jumping around between volume steps in a set non-linear pattern which changes depending on some writes which change certain bits of the register. |
 | | On system power-on of the DMG (and MGB???), the internal area isn't loaded with any particular value, however due to some unusual properties of the memory in question, the values present will almost always be roughly the same. |
