As far as I know, PS1 hacking is kind of a burden due to the sizes expected for each iso, that's why hacks and fantranslations of PS1 games are not as common, if it wasn't the case I'm sure there would have been updated rosters for the EA sport games on there already.
On romhacking dot net, there's a guy working on updating the roster for PS1 NBA Jam, so it's possible, just messy.
