// On the GameCube, the game sends a request for the graphics processor to
|
|
// transfer its internal EFB (Embedded Framebuffer) to an area in GameCube RAM
|
|
// called the XFB (External Framebuffer). The size and location of the XFB is
|
|
// decided at the time of the copy, and the format is always YUYV. The video
|
|
// interface is given a pointer to the XFB, which will be decoded and
|
|
// displayed on the TV.
|
|
//
|
|
// There are two ways for Dolphin to emulate this:
|
|
//
|
|
// Real XFB mode:
|
|
//
|
|
// Dolphin will behave like the GameCube and encode the EFB to
|
|
// a portion of GameCube RAM. The emulated video interface will decode the data
|
|
// for output to the screen.
|
|
//
|
|
// Advantages: Behaves exactly like the GameCube.
|
|
// Disadvantages: Resolution will be limited.
|
|
//
|
|
// Virtual XFB mode:
|
|
//
|
|
// When a request is made to copy the EFB to an XFB, Dolphin
|
|
// will remember the RAM location and size of the XFB in a Virtual XFB list.
|
|
// The video interface will look up the XFB in the list and use the enhanced
|
|
// data stored there, if available.
|
|
//
|
|
// Advantages: Enables high resolution graphics, better than real hardware.
|
|
// Disadvantages: If the GameCube CPU writes directly to the XFB (which is
|
|
// possible but uncommon), the Virtual XFB will not capture this information.
|
|
|
|
// There may be multiple XFBs in GameCube RAM. This is the maximum number to
|
|
// virtualize.
