### Functions

#### Apply VRAM/OAM

- **SafeUpdateSprites**: Set BG map mode to 0 (disabled) and disable OAM update + UpdateSprites + enable OAM update + DelayFrame + restore original state of BG map mode and OAM update

||||||
- **ApplyAttrmap**: Set BG map mode to 2 (pals) and delay 4 frames, and finally restore original state BG map mode. If LCD disabled instead copy all pals at once immediately

- **MenuBox**: Calls Textbox1bpp or Textbox2bpp, depending on the value at wMenuBoxUse2bppFrame, with menu location and dimensions. wMenuBoxUse2bppFrame, as part of menu data, is cleared (FALSE means 1bpp) by ClearMenuAndWindowData

#### Overworld map scrolling
|
||||||
|
|
||||||
- **LoadScreenTilemap**: From the metatile-based 24x20 map in wSurroundingTiles, load the corresponding 20x18 tiles to wTilemap. Later, BackupBGMap* from ScrollMap* copies new row/column from wTilemap to wBGMapBuffer. _ScrollBGMapPalettes populates wBGMapPalBuffer based on the tiles at wBGMapBuffer. These are read during vblank by UpdateBGMapBuffer.

#### Overworld map anchoring
|
||||||
- **LoadOverworldFont_NoOAMUpdate**: LoadOverworldFontAndFrame + hide Window with OAM update disabled
|
|
||||||
|
|
||||||
- **ReanchorBGMap_NoOAMUpdate**: LoadScreenTilemapAndAttrmapPals + HDMATransferTilemapAndAttrmap_OpenAndCloseMenu, then fill BG map with all black while Window is displayed, finally anchor map and objects. Followed by CopyTilemapAtOnce or by a *_HDMATransferTilemapAndAttrmap to redraw the screen.

|

- **HDMATransferTilemapAndAttrmap_OverworldEffect**: Like HDMATransferTilemapAndAttrmap_OpenAndCloseMenu but with slightly different scanline timing. So it's essentially like RefreshScreen minus the anchoring part.

#### VRAM transfer

#### HUD
|
||||||
|
|
||||||

|
||||||
|
- **DisableWindowHUD**: Configure LCD interrupt in hblank mode
|
||||||
|
- **LoadHUD**: Load the HUD at wWhichHUD to the top of wTilemap and wAttrmap
|
||||||

- **LoadWindowHUD**: Like LoadHUD, but for HUDs that require a Window overlay. Only does anything if hWindowHUDLY is non-0
|
||||||
|
- **ConstructOverworldHUDTilemap**: Draw the overworld HUD's tilemap into wOverworldHUDTiles
|
||||||
|
- **TransferOverworldHUDToBGMap**: Transfer overworld HUD to vBGMap1/vBGMap3 during v/hblank(s). Tilemap is read from wOverworldHUDTiles, attrmap is all PAL_BG_TEXT | PRIORITY.

- **reloadmappart**: LoadScreenTilemapAndAttrmapPals + GetMovementPermissions + HDMATransferTilemapAndAttrmap_OverworldEffect + UpdateSprites. Similar to refreshscreen, but does not reanchor. On the other hand, it refreshes movement permissions. Often used after a block change or field move, which can affect collisions.
