+reSID was written by Dag Lem.
+
+The project was started after reading an interview with Bob Yannes, the
+head engineer of the SID chip. This interview was done by Andreas Varga,
+and can be found on his SID Homepage:
+http://stud1.tuwien.ac.at/~e9426444/sidpage.html
+The reverse engineering of the SID chip would not have been possible without
+this interview.
+
+Also found on the SID Homepage is an examination of the SID noise waveform
+written by Asger Alstrup. This article was of great help in reverse
+engineering the complete algorithm for the noise waveform.
+
+Lars Haugseth has been invaluable in the testing of reSID.
+In a matter of hours after hearing about my project, he had completed a 6510
+disassembler in Perl. The importance of this was not evident to me until the
+next day when he had disassembled the music routine for "Outrun Remix" by
+Geir Tjelta, made some changes to it, reassembled, and produced a file
+containing 48K of SID register values.
+The first tests of reSID were run on this file.
+With an exceptional memory of Commodore 64 tunes Lars Haugseth has pointed
+out several errors in reSID that are now corrected.
+
+Morten Rollan and Kåre Gunnar Nesheim have provided interesting and insightful
+information regarding digital filters. Kåre Gunnar Nesheim has also kindly
+provided a 1901 monitor and a C64C from his private computer museum. His C64C
+was used to measure the MOS8580 filter cutoff characteristics.
+
+VICE has been an inspiration for this project, and testing of reSID has
+been greatly simplified by VICEs -sounddev dump option. Teemu Rantanen
+has written support for reSID in VICE, making it possible to choose at runtime
+between his excellent SID emulation and, given enough CPU power, the reSID
+emulator engine. Tibor Biczo, Andreas Boose, and André Fachat have provided
+combined waveform samples for 6581 R1, R3, R4, and 8580 R5 SID chips.
+The VICE home page is found at:
+http://www.cs.cmu.edu/~dsladic/vice/
+
+The author of SIDPLAY, Michael Schwendt, has implemented a patch to link
+libsidplay with reSID. Using his excellent tune player he has pointed out
+several bugs in reSID. He has also provided invaluable information related to
+the bugs as basis for further investigation. Most notably, the infamous ADSR
+delay bug, of which I was previously unaware, has finally been understood and
+is now correctly implemented in reSID. The SIDPLAY home page is found at:
+http://www.geocities.com/SiliconValley/Lakes/5147/
+
+A bug report from Daniel Lacasse led to the discovery of a previously unknown
+SID bug, the ADSR boundary bug.
+
+Anders Ødegård has explained aspects of analog electronics and audio
+equipment.
+
+Bob Yannes has patiently answered questions and has provided lots of
+technical information on the SID filter. Thank you Bob!
+
+Julius O. Smith III has provided much of the theoretical basis for the
+audio resampling with his "Digital Audio Resampling Home Page":
+http://www-ccrma.stanford.edu/~jos/resample/
+
+Hársfalvi, Levente has made a thorough investigation of the DC levels
+in the MOS6581 chip. His results are available in C= Hacking Issue #20,
+and form the basis of DC corrections in reSID. Levente found that each
+voice independently contributes to the DC level in the mixer. Note
+that some of the conclusions in the article are incorrect, as the
+maximum and minimum voice output levels are interchanged.
+
+The author of SIDPLAY2, Simon White, has given a lot of feedback on
+reSID. Most importantly he found and fixed a bug in the fast clock
+version of the ADSR emulation.
+
+Finally I would like to thank my business partner Stian W. Arnesen for
+putting up with all this nonsense.
