I'm not sure if this is a suitable question but I found a game that had all it is sprites and stuff saved in INA and AN format and I got curious to know which program is it.
Or is it some sort of compressing or alike and how it is usually done?
Here is the content of one of the files: http://pastebin.com/EzUsFvdG
Here is a hex dump of the above file: http://pastebin.com/CTErFBcS
The above one is the AN file and the bellow one INA.
Hex dump of a INA file which seems to be some sort of map or data file (I believe because of the layers info, etc?) http://pastebin.com/2fWn8izR
