Item description:

Fast batch installer without all the bugs and tedium in Winhiip, HDL Batcher, HDL Dump Helper GUI, etc. Uses the latest version of HDL Dump (0.9.2; included) and also has a games title database that can be used for game titles. Default mode scans all games and reports on the install type, game ID, and game title. A single option, and run the actual installation with just a single mouse right-click, and 2 key presses.

For those using Open PS2 Loader (or HDLoader) with a Network Adapter and internal HDD, installing games can be a hassle. There are several methods for installing games, of which I will mention a few: WINHIIP, HDLGameInstaller, and HDLDUMP (and variations).
WINHIIP had been my go-to installer for a long time because of its speed. By connecting the PS2 HDD drive to a PC, one could batch install games very quickly (up to a limit of 255). However, it has a number of additional limitations: some games do not install properly, the partition naming scheme does not conform to specs outlined in the official SDK, it cannot handle 2TB drives, and is limited to 255 games.

HDLGameInstaller is mainly a network installer, and is limited to about 7MB/s. All games, including CD games, must be in ISO format.

HDLDUMP has a number of flavors: HDLDUMB, HDL Dump Helper GUI, HDL HDD Batcher. HDLDUMP is a command-line toolkit for installing and managing games, and HDLDUMB is a GUI interface for HDLDUMP, but lacks batch installation. It is similar to HDLGameInstaller in terms of network installation, but seems to be slightly slower (~5MB/s). Batch installs can be done using HDL Dump Helper GUI or HDL HDD Batcher (the latter being a command-line interface). HDL Dump Helper GUI can appear to be broken on more modern systems (claims of missing Java runtime environments despite the existence of one; can still be launched via command-line with admin rights). Still, who wants to have to install a Java runtime environment just for one app?! (I personally have no other use for Java.) Both Helper GUI and Batcher, however, seem to use HDLDUMP 0.9.0, which seems to be extremely slow when using USB adapters (for me, anyway; ~7MB/s using a USB 3 SATA adapter). Moreover, Batcher was quite limited (had to install CD games separately, first; DVD9 installs would always break due to a bug in the batch code).

I recently found another batcher "toolkit" by NeMesiS after I wrote my own batch installer, but I have not tested it.
HDLBATCH attempts to combine the advantages of the above while addressing some of their shortcomings. Using a more recent version of HDLDUMP, speeds through USB3 improved to around 40MB/s -- up from ~7MB/s, though this will certainly depend on the USB adapter. When connected to the PC directly, speeds ranged between 100MB/s and 150MB/s for DVD installs, and around 100MB/s for CD installs. Since many OPL users also enjoy having game art (boxart, backgrounds, screenshots), OPL Manager is a natural choice for managing art as well as games, especially for those who use OPL over network via SMB. However, more recent versions of OPL Manager (as of the writing of this post) have started requiring game file names with game ID prefixes. These prefixes are invisible to SMB users. But anyone wishing to transfer their games to the PS2 HDD will then have to rename all their game files; otherwise the file names get used by the installers above as the title of the game. So if "SCUS_973.28.Gran Turismo 4.iso" were transferred to the PS2 HDD, it would show up in OPL as "SCUS_973.28.Gran Turismo 4" -- OPL's alpha sorting of games becomes rather useless. Currently, OPL Manger does not provide an option to revert the file names; one has to make use of a batch file to rename all the files. (This naming scheme also makes it extremely tedious to maintain individual game files.) HDLBatch will strip this prefix -- but only if it matches the actual game ID inside the game file -- and used the stripped name for the game title. Games may be in CUE/BIN or ISO format.

The 1.1 update adds a new feature for determining game titles. The update includes the use of gameid.txt -- game titles will now be pulled from gameid.txt (if it exists). If no gameid.txt is found, or no entry is found within gameid.txt, then the file name will be used instead. Users may choose to ignore gameid.txt altogether. Please see the readme.txt file on using gameid.txt.
