Change log (4.00):- New layout- UMDGen now displays information from UPDATEPARAM.SFO as well as PSPGAMEPARAM.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.- UMDDATA.BIN file generator. If your compilation is missing this file then UMDGen gives you the oppertunity to create a new one.- Ability to change 'PSPSYSTEMVER' 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.
I thought I would put together a little guide for people wanting to make backups of their UMD's. First, let me tell you that I do not endorse or condone piracy in ANY way shape or form so if you distribute your legally owned backups on the net, be prepare to face the conseqences if found by the police. Now, onto the fun bit!
First, download this and go to step 1.///STEP IFirst, in recovery mode, go to Configuration and set your USB XMB DEVICE to UMD. Now press exit and connect your USB and go onto the USB connection option under 'system'. You should now see a file called.NP9660 so now drag that onto the desktop.STEP IINow open UMDgen.exe and drag the file you just dropped into the desktop, into the large white area on the window. You should now see a 'PSPGAME' folder and a UMDDATA.BIN file. Now click on the button at the top that says 'Save'. You will be presented with 3 options,Uncompressed(.iso)Compressed(.cso)DAX(.dax)click Uncompressed, Choose a file name and directory and then click Save. When it has finished, you should have an.iso file.STEP III (optional)Now, if you want to compress it to.cso then open up UMDgen again and drag the newly created.iso file into the window and click Save, but this time press 'Compressed'I hope that this guide helps some people and if it does, please say.DarkZaK(P.S It is important you make the.iso first, or it will not work.).
Some suffer gameplay lag like GTA: Liberty City Stories and God Of War when compressed. In an iso state, these run perfectly. I don't like turning up the CPU CLOCK GAME setting because it drains the battery much faster, but do when I really have to like Medievil Resurrection. What I'm trying to do is store them as compressed CSOs on DVDs and then decompress them back to ISOs whenever I want to load other games.zip and.rar files when compressed it does shrink the file found within but when decompressed its reverted back to its original state without loss.
When converting back to ISO from CSO will anything of the original be lost? These are not the same like zip and rar and right now I'm hesitant to save them as CSO if the original will suffer loss of data when decompressed. Some people like vintage firmwares, and have 3.52 or lower. Those don't have the dumper function.Not to mention running the file directly ripped from the disc through UMDGEN makes NO sense, since it is ALREADY AN ISO.
UMDGEN is only for creating.cso's and uncompressing.cso's into.iso's, for modifying your games, and for some illegally acquired games.Not to mention, this is a bare-bones guide, which has been done millions of times before. If you wanted something new and fantastic, you would have explained all the advanced functions, like putting your own music directly on the.iso, deleting annoying, space-taking cinematics, or modify the actual graphics, like moon gravity, or purple walls.
