(For now, here. But later we need to reorganize main page little bit. This doesn't really belong into hardware category (maybe "Development" like on ps3 wiki?).)

==GE Commands List==
GE Commands seems to work in similar way as PS3 "Methods", but with simpler encoding. Single command is 32 bits wide and split into upper 8 bits of Command ID and 24 bits of data (not always full 24 bits are used). PSP hardware manuals refer to command ID as "address" which imply this are actual GE hardware registers. Non listed commands are unknown, and their behavior is not defined.

GE Commands List

GE Commands seems to work in similar way as PS3 "Methods", but with simpler encoding. Single command is 32 bits wide and split into upper 8 bits of Command ID and 24 bits of data (not always full 24 bits are used). PSP hardware manuals refer to command ID as "address" which imply this are actual GE hardware registers. Non listed commands are unknown, and their behavior is not defined.
