+ | ===== Create CHD ===== | ||
+ | |||
+ | First off, here's a comparison of sizes for the PSX-game '' | ||
+ | - In **BIN/CUE** it is 747,030,480 bytes. | ||
+ | - In **PBP** (maximum compression) it is 517,187,964 bytes. | ||
+ | - In **CHD** it is 465,566,193 bytes. | ||
+ | |||
+ | It's a LOT easier to batch convert **BIN/CUE** dumps to **CHD** than it is to convert them to **PBP** | ||
+ | |||
+ | Just place the chdman.exe into the directory where you have your **BIN/CUE** dumps, open the command line in that location (assuming you are on Windows), and type this in: | ||
+ | |||
+ | < | ||
+ | for %i in (*.cue) do chdman createcd -i " | ||
+ | </ | ||
+ | |||
+ | If you want to reverse the process, you can type in. This will create your **BIN/CUE** back! LOSELESS! | ||
+ | |||
+ | < | ||
+ | for %i in (*.chd) do chdman extractcd -i " | ||
+ | </ | ||
+ | |||
+ | For a Unix mashine you can use this little script, placed next to your ROM files. | ||
+ | <code bash| cue2chd.sh> | ||
+ | #!/bin/bash | ||
+ | for cueFile in *.cue; do | ||
+ | echo " | ||
+ | chdman createcd -i " | ||
+ | done | ||
+ | echo "All done." | ||
+ | </ | ||
+ | |||
+ | |||
+ | It might take a while, depending on how many games you have in that directory. This will also leave the **BIN/CUE** files untouched (delete them afterwards if you want to). Just be sure you have enough space on your drive before doing this. | ||
+ | |||
+ | I'm not currently aware of any batch command line methods of creating PBP files like this FIXME. So converting to CHD format will be a lot easier for you than converting to be PBP. Just enter the command into the command line before you go to bed, and the conversion process should be done by the time you wake up. | ||
+ | |||
+ | The CHD format was created with the purpose of preserving exact copies of games in a compressed format. The PBP format was created so that PSX games could run on PSPs in a compressed format (which is less compressed than the CHD format). In other words, I'd argue that the CHD format is better for preservation purposes. | ||
+ | |||
+ | **M3U** files work just like **BIN/CUE** files. You can just replace the '' | ||
