;WSCamp:A WonderSwan and WS Color emulator written by Toshi. This was the first WonderSwan emulator to feature sound as well as gamepad support, and it has a very high compatibility rate and excellent speed. It was the most accurate WonderSwan emulator at the time in the early 2000's, beating out [[Cygne]] and Oswan.

;[[Cygne]]:The first WonderSwan emulator created on the Windows platform, written by DOX and released under the GNU General Public License. It had undergone massive improvements over its original DOS beta form in the early 2000's, including better timing and fixes to the SRAM. Cygne has a high compatibility rate, but lacks in speed and does not offer any sound support. Cygne supports both the original WonderSwan and the WonderSwan Color. However, it was abandoned in 2002.

;Oswan:Oswan is a WonderSwan/WS Color emulator based on the Cygne source code and authored by David Raingeard. Improvements upon the original Cygne source include the additional of sound support and many speed improvements. Oswan also features the ability to apply several video filters as well as color schemes to add color to WonderSwan Classic titles. It has been abandoned but two variants of it were released in 2007 and 2010.

;WonderScott:The second WonderSwan/WSC emulator, this WonderSwan emulator written in JavaScript was authored by Julien Frelat (Gollum) and released by the same team that made Boycott Advance. An online web format of WonderScott was also available at its official website, but is probably permanently inaccessible. It was somehow abandoned after its last version, v0.54b, was uploaded near the end of 2001 with poor compatibility.
