Link's Awakening graphics (zladx disassembly of DX; the 1993 ROM)

The inventory bar along the bottom of the screen is the window layer. Setting it up stores window Y $80 (line 128), which leaves the bar the bottom 16 lines, and window X 7 in DX (6 in the 1993 release, one pixel further left); each gameplay frame copies the stored Y to the window register. ladx-av/inventory-window

The screen is 144 lines (gb-hardware/tile-maps), so WY 128 leaves 16. The disassembly's comments (src/code/bank1.asm#L1928-L1933) say that in the Game Boy release the inventory screen scrolled up from the bottom by moving this window, and the routine that adds 8 lines a frame to the window's Y is in the 1993 ROM too (0x9EA7, bank 2); how DX opens it wasn't traced.
