Indeed. I got lazy!
TBH, if you just wanted to do a roster update for Jam, you could now use 2K21
as a real solid base (2K20
too, actually) and probably get portraits, attributes, and text/roster in somewhere between 50-75 hours annually. I just got caught up in the opportunity to learn more about the game, do some clean-ups, and knock out some enhancements from my Hack Ideas thread post from a few years back.
The delayed season was also a big motivator in me picking up the hack again, as it gave me plenty of time to fiddle with portraits and ask more questions about ASM concepts.
Enjoy the game!
