This tool was developed to assist me to optimize files order, since it can tell me what file is being read at a certain time on a game. To use it: - Export "FileList.txt" using Isobuster. - Use "adjust_list.au3" to order and adjust "FileList.txt". - Some versions of NullDC shows the current LBA it's reading. Newer versions have this line commented... you can grab the source, uncomment and compile it if you want. Using one of these NullDC versions, play the game. - Use "lbatofile.exe", and for each LBA number you enter, the program will show you the filename.
