		zerox86 v0.01 Alpha Release Notes
		=================================

  Well, here it finally is, the first public version of zerox86!
  
  The emulator is still very much a work-in-progress, and thus still has
quite a few missing features and outright bugs.

  After you have copied zerox86.opk to your GCW Zero, it will appear under
the "emulators" section on the main menu. Note that in addition to zerox86.opk
you will need to copy 4DOS.COM to the emulated C:\ root directory. Check the
zerox86.ini file for the location of the C:\ root directory.

  You can exit zerox86 by using the "lock" slider on the right side of your
GCW Zero console. The SELECT key is used to toggle between configuration
display and virtual keyboard. Other keys can be freely mapped using the
zerox86.ini file.

  Note that by default zerox86 uses two slightly different key mappings,
one for 4DOS and one (the "default") for everything else. The default key
mapping follows the default SDL key assignment for GCW Zero, while the 4DOS
mapping uses A key for F7 (to launch the inbuilt exe/directory selection
tool) and B for ESC (to back out from the selection tool or to clear the
command line). You can change these defaults using the zerox86.ini file.

  If/when zerox86 encounters an unsupported opcode or some other error where
it can not continue, it will write a crash log file "zerox86dbg.log". This
file gets by default written into the home directory, but this can also be
changed using the zerox86.ini file. The file gets appended every time this
happens, so you can test all your favourite games and then send the log file
to me. I might be able to improve the compatibility in future versions based
on these crash logs.


  Thanks for trying out zerox86!
