The WonderSwan, WonderSwan Color and SwanCrystal are the fifth-generation handheld game consoles produced by Bandai in 1999, 2000 and 2002, respectively. It is the brainchild of Game Boy/Color creator, Gunpei Yokoi. There were three versions eventually released: A black-and-white version, a color version, and a Crystal version with an improved screen.
WonderWitch is a software development kit by Qute for WonderSwan handheld consoles.
The Pocket Challenge V2 is a handheld learning console compatible with the WonderSwan. It was sold on Shinkenzemi (進研ゼミ).

Emulators
Comparisons
- High accuracy, on par and competing with ares.
- High accuracy.
- Mid accuracy.
- Supports using external software to emulate serial port peripherals; for example, WonderFence can be used to emulate the MobileWonderGate peripheral.
- NitroSwan
- Mid accuracy, constrained by the NDS's hardware limitations.
- Due to hardware limitations, there is a maximum ROM size limit on this emulator:
- DS/DS Lite: 3 MB, can be expanded with Slot-2 expansion RAM
- DSi: 8 MB
- 3DS: 16 MB
- WSCamp
- A WonderSwan and WS Color emulator written by Toshi.
- The first WonderSwan emulator to feature sound as well as gamepad support.
- During its heyday in the early 2000s, it was the most accurate WonderSwan emulator, beating out Cygne and Oswan.
- The first WonderSwan emulator created on the Windows platform, written by Dox.
- MiracleMage
- High-level emulator for the WonderWitch platform, which allows running its software without a copy of the WonderWitch ROM.
- Does not support the WonderSwan Color; only runs "mono" software.
- Oswan
- Improved version of Cygne.
- Supports video filters and colorization.
- WonderScott
- The second WonderSwan emulator created, written in JavaScript by Julien Frelat (Gollum) and released by the same team that made Boycott Advance.
- Abandoned after its last version, v0.54b, was uploaded near the end of 2001 with poor compatibility.
Debugging
- Mesen
- Mesen has a well-regarded built-in debugger and profiler, as well as high emulation accuracy.
- Mednafen
- This multi-system emulator is said to have great debugging and cheat engine features but, unfortunately, has a CRC check function similar to default MAME. A CRC check analyses a game ROM file for any change to its data and size, so a fan-translator or ROMhacker would have to edit filenames every time for every change, which is incredibly tedious.
- MAME
- This well-known emulator of thousands of systems also has a normal CRC check algorithm to insure that the ROM file(s) of any supported game or clone, depending on the database/ROMset for a MAME version, match the data integrity and size of the same game/variant in the records. However, this does make it rather prickly for an aspiring ROMhacker. The MAME developers partly wanted this to reduce the nasty incidences of some sellers pawning circuit boards that were actually stuffed with user-made ROMhacks. There are a few ways around that - note that MAME developers still support genuine fan-translators, even for arcade games.
- 1) Try using the HBMAME or MAMEUIFX frontend, which may support loading modified ROMs.
- 2) If you don't zip the set and instead make a folder with the zipname inside your rompath with properly-named loose files inside there, MAME will fuss up, but it will run the game even though the CRCs don't match.
- 3) With the new GEnie build system, it's pretty easy to build a one-game-off version of MAME that builds in seconds on pretty much any worthwhile PC.
- make SUBTARGET=rom_name DRIVERS=src/mame/drivers/whatever.c REGENIE=1
- Oswan
- Another emulator with a built-in debugger, which is somewhat more user friendly than Mednafen's.

Exclusive to libretro cores and GroovyMAME at the moment. Also there is a project for achieving software emulators like libretro cores and GroovyMAME send the raw RGB data over a network to a core running on MiSTer, it basically turns the MiSTer into a GPU for the emulator allowing for easy setup and use with CRT TVs/Arcade monitors. | |||||||

Higher sample rates
While the WonderSwan outputs 24,000 Hz digital audio, there is nothing preventing an emulator from clocking the audio hardware at a higher effective sample rate.
