Haven't dropped by in a long time. I see you're working on 1.5.4, and thought this'd be a nice addition. In short, allowing keypad keys to be bound independently.
I actually wrote about this in General Discussion ages ago, seems we both forgot about it. So I posted a more official request. :P
As of svn rev. 4803, the keypad keys are made to send separate events when in game mode. (otherwise, keypad keys are handled depending on the numlock state and are mapped to normal keyboard keys.) This is implemented with SDL at the moment, i.e. for linux/unix/osx/etc. builds: Windows & others (dos, svgalib) will be implemented later.
glh2.exe for win32, built from svn rev. 4812 with keypad support
Windows keypad support is ready, too. I attached a glh2.exe here built for win32 from svn rev. 4812: please provide feedback, if you can.
I may add dos and svgalib support later, if I feel like it. Closing this now as done.
Working great! Glad to have those keys open now, thanks.
