This is a repo forked from svanheulen/mhqs. To run a HTTP proxy server capable to serving content to Monster Hunter 4G. I made some minor changes to the scripts. Because I only have a Japanese version 3DS, I cannot test my new code on 3DS and MH4U in other languages. If you want my new scripts to run in other MH4U/4g, or you meet problems in using the code please contact me or report issues in this repo. Followed is the original README from svanheulen " This Python script will run a HTTP proxy server capable to serving content to Monster Hunter 4 Ultimate on the Nintendo 3DS. You can report issues, get the latest version, and view the source at: http://github.com/svanheulen/mhqs These scripts work with Python 2.x only They also require the Twisted module: https://twistedmatrix.com/trac/ And my mhef module: https://github.com/svanheulen/mhef View the command line help like this: python mh4u_proxy.py -h The quest files that you provide to the script must be decrypted (and valid). The script will build all the files you need, encrypt them and keep them in a temporary folder until it is closed. Keep in mind that it will use the quest ID from inside the quest file, so make sure to change it to something different for each of your quests. The names of the quest files are irrelevant. Also note that the proxy runs on port 8080, so be sure to set it correctly in your proxy settings on your 3DS. For information on the quest file format see this page: https://github.com/svanheulen/mhff/wiki/Monster-Hunter-4-Ultimate-Quests "
