VICE derives from X64, the first Commodore 64 emulator for the X Window
System. Here is an informal list of the people who were mostly involved
in the development of X64 and VICE:
The VICE core team:
Andreas Boose gave lots of
information and bug reports about the VIC-II, the 6510 and the
CIAs; moreover, he wrote several test-routines that were used
to improve the emulation. He also added cartridge support and
has been the main head behind the drive and datasette emulation
since version 0.15. Also added several UI elements to the
MSDOS, MS-Windows and Unix ports. He rewrote the C128 emulation
adding Z80 mode, C64 mode and function ROM support, wrote the
screenshot and the event system and started the plus4 emulator.
Restructured the serial bus emulation and added realdrive and
Dag Lem implemented the reSID SID emulation
engine and video hardware scaling.
Tibor Biczo improved the MS-Windows port
and plus4 emulation.
Andreas Dehmel wrote the Acorn RISC OS port.
Andreas Matthies improved the
datasette support, the VIC20 video emulation and some ui stuff
in the Win32 and MSDOS port. He also wrote the BeOS port and
implemented video/audio capture support.
Improved history recording/playback and implented support for
video recording and netlink feature. Made the win32 user
changable keyboard shortcut system. Various bug(fixe)s. ;-)

console implementation for the built-in monitor, corrected some
REU related bugs, improved the CIA emulation, added com-port
CIA support to the win32 port, added text copy and paste support
