Just fixed the ET4000/W32i/p emulation to properly render the sprite again. It was using the old attribute controller output field overrides instead of the proper latched output it's supposed to use. This fixes the Windows mouse cursor to render properly when hardware accelerated again.

Managed to get Windows 3.1 booting into standard mode again. Hopefully no more crashes now.
Although I did experience a 'Stack error. System halted.' running edit.com inside MS-DOS 6.22 after typing a little bit?
