Adding And Assigning Files

After you run the Launcher for the first time, you'll need to add (or assign) files to be able to play the games in My Nes. Whether you choose to generate NesCartDB entries or not, you should use one of the following buttons:

  • ASSIGN button: means assign or add files using the FOLDER SCAN. Folder scan means My Nes will search specified folders for files then assign them or add them to the database.
  • ADD button: means assign or add files by opening and choosing them one by one.

ASSIGN:

  1. Click the ASSIGN button on the toolbar.
  1. In the assign window that should be appeared, use the Add button to add folders to the folders to scan list. These folders should be include the rom files (supported file types are '.nes', '.7z', '.zip' and 'rar'). Use Remove button to remove folder(s) from the list.
  • Include sub-folders in search: enabling this will force the Launcher to search all folders inside the folders in the list for file. Otherwise, only files in the folders in the list will be taken.
  • Add files not found in database as new entries: this is the most important option.

    When the Launcher search for files, it first look for entry match the SHA1 of that file inside the database. If it match, this entry get updated (ASSIGNED) otherwise, that file considered as new entry if this option (Add files not found in database as new entries) is enabled. Otherwise this file get ignored.
    That's the difference between ASSIGN and ADD.

    The entry considered as a match only if the SHA1 is matched and that entry is generated using the NesCartDB.
  • Update entries already assigned: This option is important for some cases.

    As above, when the Launcher search for files, it first look for an entry match the SHA1 of that file inside the database. If it match, this entry get updated (ASSIGNED). This work only when the SHA1 is matched and that entry is generated using the NesCartDB .
    But in case there is no entry match those conditions (or no entry generated using NesCartDB) the Launcher will use the file path to locate the match. If an entry has the same path (or the same file) this entry get updated (Size only) only if this option (Update entries already assigned) is enabled. Otherwise this file get ignored.

    This option should be disabled when: your roms collection include same file (files with the same SHA1) compressed with different names. For example, you have Super Mario Bros game file compressed in 2 archive files: SMP.zip and SMP1.zip.

ADD:

  1. Click the ADD button on the toolbar.
  1. Choose the files you like to assign or add then click open.

This work as same as ASSIGN (see ASSIGN section above) with these settings:

  • Include sub-folders in search: is DISABLED.
  • Add files not found in database as new entries: is ENABLED
  • Update entries already assigned: is DISABLED.

Now the collection is ready. Double click on and entry to play that game, or click on the PLAY button on the left toolbar to play that game as well. Also you can use the Enter (Return) button on your keyboard.

NOTES


  • The ASSIGN or ADD process may take long time, it may take hours if the files you use are compressed. When starting the ASSIGN/ADD process, keep that in mind.
  • Make sure your roms collection never include this case: your roms collection include same file (files with the same SHA1) compressed with different names. For example, you have Super Mario Bros game file compressed in 2 archive files: SMP.zip and SMP1.zip. This case may cause mistakes in entries.
  • After finishing the ASSIGN/ADD process, the entries in the table will be marked:
    X    : this entry has no file assigned or the file is missing. (This entry cannot be played)
    : this entry has file assigned and that file is exist. (This entry can be played)
