Any idea how (in a game) we can go about detecting mouse button 4 and 5?

These things are far more common now then they ever been.

I've not looked deep into it, but you could try change the array sizes in brl.polledinput.
Just a try.

After having a little fiddle in polledinput I can see that mouse button 4 and 5 dont even drop into the hook used for the mouse buttons.

After some further searching on the internet, looks like these are known as XBUTTON1 & XBUTTON2 (at least in .Net).

Yep thats it, dead simple to implement as well...

Full credit to grabel - awesome work bud!

In system.mod/system.win32.c

Add...

/*--- 5 button mouse ---*/
#define WM_XBUTTONDOWN	0x020B
#define WM_XBUTTONUP	0x020C
/*--- 5 button mouse ---*/

just after the includes at the top of the file

And add...

/*--- 5 button mouse ---*/
	case WM_XBUTTONDOWN:
		ReleaseCapture();
		id=BBEVENT_MOUSEDOWN;
		data=3 + (short)HIWORD(wp);
		x=(short)LOWORD(lp);
		y=(short)HIWORD(lp);
		break;
	case WM_XBUTTONUP:
		ReleaseCapture();
		id=BBEVENT_MOUSEUP;
		data=3 + (short)HIWORD(wp);
		x=(short)LOWORD(lp);
		y=(short)HIWORD(lp);
		break;		
/*--- 5 button mouse ---*/

To the bbSystemEmitOSEvent function located at around line 126
I added it after the WM_MOUSEWHEEL and before WM_CLOSE case statements.

Recompile your mods and you are golden.

MouseDown(4) and MouseDown(5) can then be used to read these buttons!

Sounds like something that could/should be updated in the 'official' version?
