tutorial about put a different team logo in the game

i want to update my 70`s retro-patch and create a new 60`s retro-patch and i have a question:
Can someone give me please a tutorial about to put a different,new team logo to the nba rosters?

Yeah, I don't see why this isn't working either.

If we dump the logo files in /sgsm, it works fine - as we can see with the OKC patch.

But if we try to create a brand new 2 letter abbreviation in teams.dbf and name the logo files in /sgsm that way, it doesn't work.

That approach worked fine for paxson with stadiums; what else needs to be done for it to work with logos?

It might sound like a stupid question, but are you importing the updated logos back in to the .big file or are you placing the .fsh files in the sgsm folder directly? Only the .big files will be read from the sgsm folder.

If you're doing that already, you'll also need to hex edit the abbreviation on the files inside the .big file (alternatively, I believe you can change them with DOLFFIN) to match the new team abbreviation in addition to renaming the .big file itself. Otherwise the game will find the .big file alright, but won't find any appropriate namely files inside it.

Not sure what I was doing wrong in trying to bring back Seattle - I exported all the .big's to /sgsm; then I renamed all the files within the .big using biggui, then I hit rebuild. But the game acted like everything was blank still.

Is there any thing to be done regarding compression?
