UMDGen is a Windows utility that is used to create and/or edit UMD compliant ISO image files. You can use it to replace, delete, add and apply PPF patches to the files. The ISO image files can then be played on some PSP systems. ==Features== *Create and/or edit UMD compliant ISO image files. *Apply PPF to ISO. *Batch Converter (uncompressed ISO, DaxISO and CISO). *File Search within ISO. ==Controls== '''Shortcut keys:''' Ctrl+F - Add a new folder to the compilation Ctrl+N - Create a New compilation Ctrl+O - Open an existing UMD Image file Ctrl+S - Save the current compilation as a new ISO Ctrl+C - Save the current compilation as a Compressed Image (CSO) Ctrl+D - Save the current compilation as a Compressed Image (DAX) Ctrl+P - Display the Image Properties window Ctrl+R - Rename the selected File/Folder Ctrl+E - Extract the complete contents of the opened ISO Image Ctrl+M - Use the selected file as the soruce file when relinking Ctrl+L - Relink the selected files to the already selected source file Ctrl+X - Exit UMDGen ==Screenshots== https://dlhb.gamebrew.org/psphomebrew/umdgen3.png ==Changelog== '''v4.00''' *New layout *UMDGen now displays information from UPDATE\PARAM.SFO as well as PSP_GAME\PARAM.SFO. *Optimize button added. This function automatically detects and resizes dummy data, removed un-needed padding and dummies the contents of the UPDATE folder (if detected). *Non-PSP standard images can be forced to be read by the user. Upon detection, UMDGen will let you know the image is non-standard and you can choose wether to continue and have UMDGen attempt to read it. NOTE: depending on the individual image, this could cause UMDGen to close if it encounters data it isn't expecting - but the general rule is if the psp can read it then presume UMDGen can too. *UMD_DATA.BIN file generator. If your compilation is missing this file then UMDGen gives you the oppertunity to create a new one. *Ability to change "PSP_SYSTEM_VER" in PARAM.SFO to different firmware version. (Use +/- key while version is selected) *'Drop Open' images re-introduced due to a lot of requests to re-add it to UMDGen. *Complete CSO + DAX support. You can now edit compressed images the same as uncompressed images. Dax support now includes the use of Non-Compressed areas feature. *'Ezip' format removed. We didn't think it was worth keeping this format since it only had very limited support anyway. *'Dummy File' option added as requested by many users. *v3.50 still had trouble with one or two problem images. A lot of code to do with the reading/writing process has been restructured and these problems should now be fixed. ==External links== * Official website - [https://web.archive.org/web/20090221184411/http://umdgen.ps3news.com/ http://umdgen.com] (archived) * Romhacking.net - https://www.romhacking.net/utilities/1218/
