#define | PA_DualLoadSimpleBg(bg_select, bg_tiles, bg_map, bg_size, wraparound, color_mode)
| Simplest way to load a Background on both screens
#define | PA_DualLoadRotBg(bg_select, bg_tiles, bg_map, bg_size, wraparound)
| Load a background fit for rotating/scaling ! Warning, you must use PA_SetVideoMode to 1 if you want 1 rotating background (Bg3 only !), or 2 for 2 rotating backgrounds (Bg2 and 3). The background MUST be in 256 colors
#define | PA_DualLoadBg(bg_select, bg_tiles, tile_size, bg_map, bg_size, wraparound, color_mode)
| Simplest way to load a Background. Combines PA_InitBg, PA_LoadBgTiles, and PA_LoadBgMap
#define | PA_DualLoadPAGfxLargeBg(bg_number, bg_name)
| Completely load and initialise a background with infinite scrolling (usefull if larger or wider than 512 pixels), converted with PAGfx. Background on both screens, as one
#define | PA_DualLoadLargeBg(bg_select, bg_tiles, bg_map, color_mode, lx, ly)
| Completely load and initialise a background with infinite scrolling (usefull if larger or wider than 512 pixels), on both screens
#define | PA_DualLoadLargeBgEx(bg_select, bg_tiles, tile_size, bg_map, color_mode, lx, ly)
| Completely load and initialise a background with infinite scrolling (usefull if larger or wider than 512 pixels), but here you can put yourself the tile size...
