[Homebrew] Character bank issue in Atop The Witch's Tower WS

[asiekierka]

Game download, tested on NitroSwan 0.5.0.

To reproduce, start game, press START, then move in any direction to unpause the player. You will see a message box pop up with white text, whereas on Ares and real hardware the text is yellow.

From a programmer perspective, the difference that is being shown here is that the text is yellow if using tiles 512-767, and white if using tiles 0-255; that is, my suspicion is that there's an issue with the implementation of bit 13 (character bank) in the 2bpp color mode.

This can also be seen in the WSC Bios settings and in Sorobang in color mode.
