MLB The Show modding on PS3 COULD be possible

[MauerMorneau09]

Hey everyone,

Not sure if anyone still visits here, but I made some discoveries in regards to the potential of MLB The Show modding on PS3. I was able to extract models/textures from MLB 09 and thought it might be cool to show it off, if anyone is interested in that. At the very least, we now know that objects/textures can be extracted. As for getting them back in-game, that's something far beyond what I'm capable of.

Keep it up, hopefully we will have something in the future.

@MauerMorneau09, Congratulations for the progress!!

I did the something similar for MLB14TS PS Vita/PSTV. I also successfully inject updated files like textures (uniforms, player faces, stadiums, logos, ...), music, schedules and a bit more.

On the other hand, I am able to edit roster files for PS Vita/PSTV. These roster updates would work as is for PS3 too! The only problem left to solve is to find the checksum algorithm that MLB14TS PS3 applies to game saves, otherwise you get an error message when loading it.

Do you mind to share the player model file from the first image?

The textures you got, look pretty similar to those from MLB14TS PS Vita. Most likely, the resolution for the PS3 version is higher.

MauerMorneau09 lorak you guys are on my wavelength. You can decrypt and unpack the MLB file saves - copy the MLBTS roster or franchise file datasave from PS3 to USB then transfer to PC - decrypt the PS3 datasave using Bruteforce (4.6 works) - in the decrypted window double click on the largest file - flatz savedata routine will unpack it - in the popup window showing the unpacked files find the largest files - open file location for the extracted files - open with a hex editor or tool of preference.

MLB 08 through 11 have larger file size. MLB 12 - 16 substanitally smaller but uniform in size. Carry forward of franchise or RTTS ran from 15 through 20 which might indicate that file structures stayed somewhat stable during that period as well.

You can find ascii text for certain players, unlocked HOF's, franchise roster, and machine code for variable stat data, which would get loaded in RAM. IMHO aside from a RTTS or created player, all the MLB player descriptive data is hard coded on the drive, which is what has made this such a tough nut to crack.

Looking for updated PS3 MLB 15 or 16 (last PS3 version) rosters - historic rosters and to unlock the golden era & silver era teams & players. The latter can no longer be done in game play because the servers have been retired. I have them unlocked in MLB 10 from the day, but the file structure is substantially different from succeeding years..

That's awesome! Sounds like you're much more educated on this stuff than I am. If you wouldn't mind sharing, I'd love to know how were you able to mod those files. My goal is to make any PS3 The Show game moddable like NCAA 14, NBA 2K, etc. I used a program called VulkanRipper to extract these, but it's limited since it can only pull what's currently loaded and it's not necessarily extracting the raw files. I included the gltf files that were extracted. I just imported those into Blender as is. If you have any ideas on where to go from here, I would love your help.

Thanks for the files, I will have a look.

Given that you pull all those files via VulkanRipper, it most probably means that you did it by loading the game in an emulator, maybe RPCS3. In general, there are a lot of similarities in the game file structures of PS3 and PS Vita games, the main difference is that PS3 sticks to big endian and PS Vita to little endian format.

Perhaps I would be able to extract the files from a version of MLBTS for PS3 as I did with MLB14TS PS Vita, just working with the raw game files.

By the way, the 2024 update for MLB14TS PS Vita will arrive soon. Meanwhile, you can check last year's thread.

Impressive work! Yea I had to use VulkanRipper through RPCS3 since I've been unable to get the files through quickbms or any other extractors. Looks like Vita also uses WAD format like the PS3 version, correct? Really the biggest hang up right now is finding a way to unpack that WAD, which for MLB 09 is 11 gigs (no idea if the size would cause problems). I've asked around to see if anyone has any info or a script to unpack it, but so far no luck. Let me know if you're able to find anything out. Even though I'm a novice with this stuff, it fascinates me and I'm eager to see what the possibilities are.

Keep at it, this would be awesome.

Re: MLB The Show modding on PS3 COULD be possible

This is an interesting thread! I didn't think anyone would do anything like this. It's really cool to see the extracted model from the PS3 version.

Has anyone had any progress here? I have done texture work on NCAA Football but that’s about the limit of my ability.
