I've been using DJGPP for the first time recently and can't seem to enable mouse support. What's the best way?
Thanks for any help.

Gosh, this takes me back! You need the software interrupt 33H - see http://www.sentex.net/~ajy/mouseint.html, and a tutorial of sorts at http://www.writeka.com/emage/mouse_events.html.

My best ever hack was to add mouse support for the hercules graphics mode of a commercial game, via int 33, by adding 8086 machine code to the executable using Borland's debugger. I remember feeling remarkably clever for the rest of that day.

Cool! Hercules graphics - cringe...that was my first pc, with 8088 clocked to turbo 12mhz with 10Mb hard drive and 5 quarter inch floppy 360K...happy memories...That's a neat hack you did there...

By the way, at the time, I knew it could display graphics, and had to put on a CGA emulator to play CGA games, until I came across Moraff's world which was beautiful under Hercules and ditched the CGA emulator altogether...

int33h... I used it in QuickBasic applications to add mouse support... it was definitely cool at those times!

Here's a comprehensive list of Int 0x33 functions here. This is from the Ralph Brown's Interrupt List, which can be found here. Also here's a link to the mouse handler for DJGPP. Also, here's a link to the MSDOS programmer FAQ here, in which you will find the information about the mouse.
Hope this helps, Best regards, Tom.
