Fixed freezing on Mansion's 2nd Floor Right Stairs for hardware accurate emulators like Mednafen. Original hardware to be tested. Thanks to MeganCrass for helping out with this one.
This hack allows you to turn and strafe at the same, ie. adds circle strafing to the game. It was relatively easy to develop after the original source code was released yesterday, even with zero 65816 / GSU assembly knowledge, but there is still one little missing feature: the strafing speed stays the same regardless of whether the run button is pressed down or not. A value that is halfway between the original walking and running strafe speeds is currently used.
Fixing this requires either adding some GSU instructions (instead of just overwriting a couple of existing ones), or a different approach for hacking in support for handling turning and strafing separately of each other. It is quite playable already however.
