Vincent Penquerc'h (lyrian at kezako dot net).
Added the D_DIRTY flag and mouse button press/release events to the GUI system, optimised the 256 to truecolor blitting code to avoid repeated conversions of the palette table, added scare_mouse_area(), added the yield_timeslice() function, added the update selection function to the grabber, added the XCRP and YCRP properties to datafiles in general, and made various other bugfixes and improvements. Responsible for the big header split up, and did loads other stuff too.

Integrated the concepts of scrolling and edit_proc objects.

Thanks!

First, a big thank you to all the people who help me test and debug this code. It sometimes gets frustrating to receive hundreds of messages saying "it doesn't work!", but they are useful all the same...

Andre Baresel (baresel at informatik dot hu-berlin dot de), and Craig Jackson (Craig dot Jackson at launchpad dot unc dot edu), provided a tremendous amount of information about SB hardware.

Benji York (Benji at cookeville dot com).
Provided hardware information for the Gravis GamePad Pro.

Charles Mac Donald (cgfm2 at hooked dot net).
Showed me how to set some cool tweaked VGA and mode-X resolutions.

Charles Sandmann (sandmann at clio dot rice dot edu), DJ Delorie (dj at delorie dot com), Eli Zaretskii (eliz at is dot elta dot co dot il), and everyone else who has contributed to djgpp. I love it.

C. Schwerdtfeger (schwerdt at physics dot ubc dot ca), for his help (and enourmous patience!) in getting the SB Pro-I MIDI driver to work.

Finn Thoegersen, Nordbanevej 3 C, DK-7800 Skive, Denmark.
Most of my SVGA hardware information came from his VGADOC package.

Eric Jorgensen (smeagol at rt66 dot com).
Varmint's Audio Tools (VAT) gave me many useful ideas about how to play MIDI files.

Jamie O'Connell (JamieOConnell at msn dot com).
Several of the new Adlib drum patches, and the specifications for the .IBK file format, came from his SBTimbre package.

Jean-Paul Mikkers (mikmak at stack dot urc dot tue dot nl).
MikMod was the source of a lot of information about programming the SB, and also gave me the idea of dynamically reprogramming the PIT to get a really high resolution timer.

Joel H. Hunter (jhunter at kendaco dot telebyte dot com).
His SB library for djgpp is excellent, and helped me a lot.

John Pollard (74723 dot 1626 at compuserve dot com).
The FM instrument definitions are based on his MID-KIT library.

Kendall Bennett and all the other cool people@SciTech Software.
These guys gave the world UniVBE, the VBE/AF API, and a lot of free information and example code. Plus they very kindly sent me a copy of the VBE/AF spec when I wanted one.

Kris Heidenstrom (kheidens at actrix dot gen dot nz).
His PC timing FAQ was a big help.

Mark Feldman.
It goes without saying that the PCGPE was an invaluable resource.

Michael Abrash.
You just gotta love that man...

Paul Fenwick (bg914 at freenet dot carleton dot ca).
Various bits of the mode-X code (notably the split screen stuff) came from his XLIBDJ library.

powerjaw (powerjaw at dnai dot com).
Sent me a Sidewinder gamepad so I could fix some problems with the driver for it. What a cool thing to do...

Robert Grubbs (rwgrubbs at vt dot edu).
Provided hardware information for the Sidewinder joypad.

Robert Schmidt (robert at stud dot unit dot no).
The register values for the 400x* mode-X resolutions came from his TWEAK program.

Tom Grandgent (tgrand at canvaslink dot com).
Organised and hosted the Allegro mailing list. Hurrah!

Vladimir Arnost (xarnos00 at dcse dot fee dot vutbr dot cz).
Provided hardware specs for the OPL3 chip.

Frank Zappa, Mike Keneally, Pink Floyd, the Doors, Tori Amos, and all the other great musicians who provide me with things to listen to while I am programming.

My parents, John and Nancy.
I would never have made it through all those late night coding sessions without the cafetiere they gave me last Christmas :-)
