Pressing C will reset the VRAM viewing address to 0. Such occurrences are: starting the game from title screen and dialogues between levels, including the map screen.Īctivate this code and press Start on the title screen. Every time the screen goes to black to be replaced by another screen, the CHR test will occur. It changes the black-screen-replacing subroutine a bit.
The most safe and useful way for seeing this test is using the Action Replay code 000C5E:0376. Calling it during a level causes the game to hang. It's better to call it at the title screen or between levels.
However, if you skip it and jump to the buried code, you will get nothing. The last one is performed once at the start of the game. Normally it should be called by instruction 00000376: JMP ROM:$00023E84, but it's skipped by previous instruction. It allows you to look through current VRAM and to change palettes. This code is not complete so it won't work properly and can cause glitches.
