is a tool that is used to create and/or edit UMD compliant ISO image files.
The ISO image files can then be played on some PSP systems.
UMDGen is a backup tool only. You can only use UMDGen to backup your legally owned Playstation Portable games. UMDGEN.COM does not condone piracy in any way or form.
Changelog:
New layout
UMDGen now displays information from UPDATEPARAM.SFO as well as PSP_GAMEPARAM.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.
