To make the ZLIB Exploit work, simply add "DDDDDDDDDDDDDDDDDDDDDD.zip" to your main 'chars' folder and add "DDDDDDDDDDDDDDDDDDDDDD.zip" to your select file. It is The Last Early Summer Rain's zlib method so if mugen closes, opens another exe called 'MORTALIS' and plays the match that means it works, as it uses a extensionless exe like TLESR.

This might be changed in the future.
