MaiDumpTool (Chinese Dump Tool) V233.0 released for PS Vita
So it was brought to my attention by /talk forums user P3T3 that apparently there is a Chinese game dump tool. So I decided to look into this so I could report it to all of you here at wololo.net. You’d think that considering this is v233.0 of this app, we might have heard about the 232 versions prior to this, but we didn’t (233 is an equivalent of “LOL” on the Chinese internet so that’s probably the reason). So what is it and what does it do? Let’s go into that shall we?

Can extract/decrypt games and updates (Both physical and digital)
● Can extract the updates by themselves (Both physical and digital)
● Can install the games to your VITA directly, instead of dumping to a VPK.
● Can decrypt and load games that use the sce_modules
● Automatically loads all plugins in ux0:/plugins/
● Saves the original eboot to mai_moe/eboot_origin.bin
● Does not support grw games (With updates built into the cart)
● Does not support some of the rare self loading games (Uncharted: Golden Abyss)
● If the game can not be normal operation of the solution (in two attempts)
The eboot.bin replaced mai_moe / eboot_origin.bin
Deletion two reserved sce_module / libc.suprx and sce_module / libfios2.suprx with _m of (???)
● This version does not support DLC, this will likely be added in the next version. (If there is a next version!)
● When dumping a game, the user can choose to install it to their VITA directly from the game, or pack it into a compressed VPK (Because the latter takes a while)
● PLEASE do not let the screen lock, as this will fail the dumping process.
● This tool is for educational and research purposes only! Please delete it within 24 hours, and do NOT use it for commercial use.
So from what I can gather it is more or less the same as Vitamin 1.1 but there are confirmed reports that it can dump games that Vitamin cannot, since it dumps all the .suprx files correctly.
I tried it, and it’s real. The tool is compatible with games that aren’t compatible with Vitamin (I tested it on Trillion) and dumps the .suprx files, which is pretty cool.
However there is something else that you should be aware of, as mentioned by AIDA:
So it looks like the tool extracts the game’s files, decrypts the eboot, modifies the eboot to read the modules externally and to load plugins in ux0:/plugins/, then puts all those files in ux0:/mai/<Game’s TITLEID>/. You would need to then take the files inside of the game ID’s folder, throw those into a VPK, and theoretically, it would install like a normal game. I’m testing with a small PSN game now.
Keep in mind that:
– After you chose to install the game (the second option on the main menu), the dump is REMOVED from your system (it likely moves it instead of copying)
– This may also delete your save games for the dumped game, when you choose to install it. Additional testing required, YMMV.
Note from wololo: I have set a policy to not allow links to tools like Vitamin or this new game dumper here on wololo.net, including links to third party websites that host the tool. Typhoon_Neon properly linked to his sources for this article but I have intentionally removed the links. Apologies to the people who deserve credit for their work here but I have to draw the line somewhere.
