# The OS/2 version of Billy

## Upgrade your DOS CD-ROM to the full OS/2 version

1. Download the general CD-ROM Upgrade to version 1.30b for DOS and OS/2 (730 kb) and unzip it in the directory where you installed Billy.
2. Make sure the EMX run-time library version 0.9 (or later) is installed. If you can run the command `EMXREV` then EMX is installed. If not, download it.
3. For more info, read readme.os2 and install.os2 (also included in the zipped package)

## Order Billy

You can buy the DOS Billy-CD that you can now upgrade to a native OS/2 version. Simply order Billy via BMT Micro and remember to ask for a notification of the OS/2 version. In this way we can get a measurement of the interest in the OS/2 version. If the sales are high enough we will produce a dedicated OS/2 CD, but right now it seems there is no commercial basis for this. If however we do, BMT customers will recieve a copy at a very favorable price.

## OS/2 specific features

- DIVE, VIO and PM graphics support using the EMX-VESA library from Johannes Martin.
  (A current limitation to DIVE is that you have to choose 256-colour in your system settings for your desktop)
- DART sound support.
- Joystick support using the Advanced OS/2 Joystick Driver.
- CD-audio support.

## Bugs fixed

- Better CD-ROM detection. Fixed problems with systems with drive letter gaps (e.g: C,D and F but no E drive)
- A bug would crash the game if ACCENTSTR wasn't defined in TEXT\LANG.TXT.
- VESA_DIV.DLL is now "desktop-aware": when you change to another application monsters no longer dig corridors in your desktop.
- Mouse pointer is invisible in VESA_ALL.DLL
- The game no longer mess up fonts and desktop graphics.
- Keyboard no longer jams
- More informative error messages.
- All resolutions 640x480 and up now supported (using -g option)
- Display centered when using higher resolutions than 800x600 (if you use -g option)
- VESA_PM.DLL no longer runs upside down.
