However, this does make it rather prickly for an aspiring ROMhacker. 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. These systems don't tend to have many good alternative emulators, let alone ones with good quality debuggers.

This is likely the reason why there have not been many hack and fan-translation patches being provided publicly for any game on several systems that are covered by Mednafen such as Wonderswan (this page's topic), Neo Geo and PC Engine/PCE CD. 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.
BEST WONDERSWAN EMULATOR CODE
Oswan Oswan is a WonderSwan/WS Color emulator based on the Cygne source code and authored by David Raingeard. Cygne supports both the original WonderSwan and the WonderSwan Color.
Cygne has a high compatibility rate, but lacks in speed and does not offer any sound support. It had undergone massive improvements over its original DOS beta form in the early 2000's, including better timing and fixes to the SRAM.
BEST WONDERSWAN EMULATOR WINDOWS
Cygne The first WonderSwan emulator created on the Windows platform, written by DOX and released under the GNU General Public License. It was the most accurate WonderSwan emulator at the time in the early 2000's, beating out Cygne and Oswan. 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.
