| Loop(a=argument count of callback, r=number of executions, d=data to loop over, e=callback block)
This is complicated, need some examples... keywords "a" and "r" are always required, keyword "d" is optional: if provided, the loop behaves like a "for each" loop over the provided data, if not provided it behaves like a "for" loop between 0 and r.

| Video_LoadTileMap(d=file id, t=type, n=layer count, i=layer indices, c=layer IDs)
d: [[Tile map file]] ID<br>
t: Type, how layers are assigned to GBA background layers: 0=BG0, 1=BG2+BG3, 2=BG3, 3=BG1, 4=BG1+BG3, 5=BG2+BG1, 6=BG2+BG3=BG1, else=BG2 but invisible in REG_DISPCNT)<br>
n: Layer count, how many layers to load. Defaults to 1. For example, t=4 and n=1 would load only BG1, t=4 and n=2 would load BG1 and BG3.<br>
i: Layer indicies: Specifies which layers to load from the tile map file, via indices into its layerDefinition array.<br>
c: Layer IDs: Specifies which layers to load from the tile map file, by referencing the TileMapLayer.id field<br>
Precedence for layer selection: keyword i, else keyword c, else defaults to [0, 1, 2].<br>
If the tile map file contains a tile set, it will also be loaded into VRAM as well.

| Video_LoadTileSet(t=type, c=part ids, d=tile set file id, m=tile map file id, s=load offset)
t: Type; only two relevant cases: If 0 (=BG0), then load offset will be ''forced'' to 0x400 tiles, irrespective of the m and s keywords. Otherwise, the m and s keywords are used.<br>
c: [[Tile set file]] part IDs to load (1-n)<br>
d: Tile set file ID<br>
m: [[Tile map file]] ID, only used to determine the load offset.<br>
s: Load offset in tiles<br>
''Load offset explanation'': Tiles are copied into VRAM starting at that offset. By specifying different load offsets for different tile sets, multiple tile sets can coexist in VRAM simultaneously. If both m and s are specified, m takes precedence.
