work with some files please professionals only bid on this project

I need help with a software and i found some files i need to work with in order to handle them. They have binary data and text strings, the headers in those files doesnt match any known format ive researched. The files extensions are MER, MERDEBUG, CHD, SX. Those extensions have no much information on the web, so i need someone who can identify and work with them. I have reviewed many of the software files and it also uses LUA to made these files: I found some text in other plain text files that suggets some luas cripts were used to generate some files. I hope i have provided enough information about my request. Feel free to ask about anything required. P.D I've attached a sample of the files, there are ones that have the same name, but different extension (CHD, LUA).
