RichK Posted March 7, 2005 Share Posted March 7, 2005 It doesn't work on PS2 roster files, but I'm currently working on an MVPedit type program for PS2 rosters. It is very slow work, as I have to determine all the data locations by trial and error. I've been working on this for about a week and have identified about 30+% of the basic player data and 8% of the ratings. Once I am finished, you should be able to take a PS2 roster save file and edit it then use it in the game WITH NO MODCHIP/HDLoader required (only an AR MAX/X-PORT/etc). PC file to PS2 conversion may be looked at once the initial project is complete. I would estimate that I'm probably a month away from a beta version. Progress will be posted here: http://ps2mvped.blogspot.com/ Link to comment Share on other sites More sharing options...
krawhitham Posted March 7, 2005 Share Posted March 7, 2005 have you changed anything and tried to reload the save? Last season when I fooled around with it, I changed someones speed (Speed I think it has been awhile) and then tried to reload the save I recieved, not a valid ps2 save or something like that. I assumed it has a checksum value in the save somewhere Link to comment Share on other sites More sharing options...
rglass95 Posted March 7, 2005 Share Posted March 7, 2005 Yes, that's what I am curious about. Also, I question the sanity of anyone that would basically rewrite MVPedit. :p Link to comment Share on other sites More sharing options...
RichK Posted March 7, 2005 Share Posted March 7, 2005 Haven't tried yet. There is something going on because more data is changed than what you edit. That's on my list to try out before I get too far in the process. Link to comment Share on other sites More sharing options...
rglass95 Posted March 7, 2005 Share Posted March 7, 2005 Yeah, that's probably the checksum. You could make one change to your roster, such as skin tone from 2 to 3, and it would modify the checksum and about 5-10 different values within the file in addition to the player record. Even if you can't write back to the file though, you could read from it and create a stat dump like MLBTinker did. Link to comment Share on other sites More sharing options...
krawhitham Posted March 7, 2005 Share Posted March 7, 2005 If it is a checksum, you could make a util that would convert a save to a PC roster in .dat format. It would help PS2 roster builders that have done alot of work on their roster but want to do something that only editing on a PC will allow (like long player names) someone could then take that DAT roster and make a new roster save inside the game Link to comment Share on other sites More sharing options...

Hopefully, I can figure out the checksum (if it exists) and create a PS2-readable roster. If not, a dat file or stat dump will be pursued. Link to comment Share on other sites More sharing options...

krawhitham Posted March 8, 2005 Share Posted March 8, 2005 no and the PS2 one is not done yet, he has to overcome the checksum problem the xbox along with checksums also has the save file signed by a special key (all xbox saves are signed not just MVP, microsoft requires this of all game makers) Link to comment Share on other sites More sharing options...
RichK Posted March 9, 2005 Share Posted March 9, 2005 Good news. I don't believe that there is a checksum in the PS2 roster file. However, it does recalculate the salary everytime you edit a player. This may be causing the invalid roster issue. I'm going to make some edits and try to reload the file on the PS2 tonight. I'm making progress on the PS2MVPEd program. Just finished the team data and I found the roster (lineups/batting order/defense) in the file. The rosters will be difficult to decypher and will take some time. Most of the player data is decoded. I'm only missing face numbers and some other contract data. This has been rather difficult at times, as the data is not stored with IDs for each player like in the dat files, rather they are all based on sequence in the file. So you have to read in the data, then start looking for everything in the file piece by piece. Link to comment Share on other sites More sharing options...
