This page describes the structure of the buffer for [[GSP_Shared_Memory|GX command]] 1 with the registers at [[GPU|0x1EF018E0]]. This buffer is used for GPU commands including OpenGL commands, each 8-byte entry in the buffer is a command. Cmd+0 is the command parameter, and cmd+4 is the command header. | This page describes the structure of the buffer for [[GSP_Shared_Memory|GX command]] 1 with the registers at [[GPU|0x1EF018E0]].
