After moving to Citra, I was able to remedy the game from crashing by changing all the values starting from offset 273 to offset 821 from "FF" to "64".
I also changed some other values that were edited in the Denpa Men party to one of my other save files that the game created to try to make sure nothing went wrong.
Judging by what I currently see, this gave me all 8 slots for the Denpa Men Party, and all the clothes and items in the game with random numbers accompanying them.
If I spent more time fiddling around with this, I could get all the items to 99 along with the clothes, leaving all the key items at 1 for story progression if it gets halted, like it did using the Save Editor for TDM 3, but either than that, I solved the problem that the OP didn't check for.
