Modding of old 2K football games

Postby xflamexofxhopex » Mon Jul 29, 2019 11:46 pm

So I figured out how to mod the uniforms on College Football 2K3. May lead to a breakthrough for other 2K games. See attachments (yes I know Nike is on wrong side of pants, just wanted to see if it would work) and I also modded the Bama logo to update it too.

I'm able to edit the helmet on the models now, as well as helmets in the selection screen now. See attached.

Excellent! I was messing around with CFB 2k3 on Dolphin recently as well. Additionally, although Dolphin struggles emulating EA sports games with the same speed as 2k titles on Android, I've been messing with NCAA football on Dolphin/PC. I am an Oregon fan and managed to get the 'Joey'-era unis into NCAA 2005. I used the texture dump/load features in Dolphin to dump textures from NCAA 2003 and 2005 and then renamed the 2003 textures to the appropriate file names. Check it out (attached screenshot). This is just a player I created btw, not Clemens.
If we can easily swap unis and clearly edit them (I mean, the image files are editable right in the file system), I would love to see editors working for NFL 2k3, CFB 2k3, and EA NFL and NCAA gamecube titles.
Imagine what is possible on our PCs if not our phones!

I'm able to get NCAA 05 and Madden 05 running stable on my Pixel 3 and have been modding 05 and showing them on my phone. I'm in the middle of modding using the images from the NCAA 14 mod for Madden 08 on PC and making small adjustments. Theoretically it should be easy to mod Madden 08 on Dolphin though, given that Madden 08 on PC is modded heavily.

Awesome! Do you have a proper roster editor or hex format documentation for NCAA 2k3 or NFL 2k3 rosters?

I do not. I am still needing assistance with that part. Any pointers?

Not yet, I pinged King Javo but no response, so at the moment I think someone has to figure out the following:
1. encapsulation format for gamecube. if you look at what minotauri did with his great work on ps2/psp conversions of madden rosters, I believe he figured out that a few leading hex digits could be taken out for editing with madden pc editors and put back in. we have to figure out how gamecube save formats work and unpeel the onion to get at the 'real' hex data
2. decoding. we have to figure out the hex format of the data. Few ways I can think of is to edit a roster in game with known values and then open it in a hex editor and compare before/afters to help nail down offsets. We can do the same in other games/platforms in the 2k family and try to see if we find commonalities.
3. document. we have to document our findings as even with just this people can edit rosters manually
4. implement editor (lower priority). I know this sounds silly but I don't think an editor is that important if enough savvy people have the documentation in their hands. This is something a lot of folks could implement as long as they have everything documented.
As for me, I'm in and out of my efforts here so I should not commit anything to the community as I used to have more time years ago. But I am happy to guide, consult, test, whatever.

Hmm, is there any way you can do that, or do you want me to try? It sounds like you a little more experience with hex editors than me.

:)

Honestly, I am always putting my toes in on these things. The thing I can't commit is how much effort I can spend or when. The last thing I want to do is disappoint the community. If I make progress I will post about it, surely.
