I want to customize arrow key to WASD
Is there any way of this?
Actually It is not uncomfortable to control by arrow key but think WASD will be more better

For Wizardry 6 and 7 DOS versions use the DOSBox Mapper (Ctrl+F1).

Wizardry Gold is a bit more fiddly. Install and set it to use the script at the bottom of [url=http://www.autohotkey.com/board/topic/51687-toggle-wasd-keys-to-arrow-keys-help/#entry472519]this forum topic. AutoHotkey must be run as an administrator (for Vista and newer) since Wizardry Gold also runs as an administrator, otherwise it can't interact with it. You can then toggle WASD on and off with Caps Lock.

Wow very thanks! You are my lifesaver
Btw, Do you know how to return to default from customized key mapping?

Delete mapper.txt in the game's installation folder.
