UMDGen Changelog

What's new in UMDGen 4.00 Build 61205.01

Oct 19, 2010
  • 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 whether 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.
