HDMA layer 3 position in status bar IRQ

Waiting SMW Patches → HDMA layer 3 position in status bar IRQ

Submission Details

Name: HDMA layer 3 position in status bar IRQ
Author: spooonsss
Submitted: by spooonsss
Tool: Asar
Requires Free Space: Yes
Bug Fix: No
Featured: No
Description: Uses HDMA in IRQ to update Layer 3 position. This fixes visual issues when HDMA is used to update positions on other layers (e.g. Effect Tool parallax), which may interleave with the CPU storing to position registers in the status bar IRQ routine. It also saves h-blank time, so more HDMA transfers may be used.
Mode 7 rooms are unchanged.

Uses 5 bytes of free RAM. Not SA-1 compatible. Requires FastROM.

Shame no SA-1 support ): Still sounds super cool though!
