Sorry for bumping the topic
Thanks you for sharing the code.Here is what I found for the match rule modifier

PAL)
006BA510 000000??
For NTSC try the offset conversation method
Before I begin,there is something you should know:
I used PS2RD,the most convenient cheat device developed for PS2 to test
I used
A.H. Hardy 2014 Universe Era Mod and
Dadydodo's moveset mod
Illegal/redundant superstars will be placed inside the ring and they have to go back to their location(apron,outside,etc...)
Like this,if you actived the code "4 Man Tag Team Match" and you played "6 man Tag Team Match",the 5th & 6th superstar will be in the ring and he has to 'return' to the apron.

- This only affects commentary,introduction,pre-match warm up,superstar placement,environment,post-match celebration,slight change in ranking.
- It doesn't change their ROLE's (manager,tag team partner,active superstar,referee) or set SPECIAL match event,backstage - area.
- So we need the address that store the match before it was actived so you could change rule and maybe assign to their correct ROLE,otherwise some will be meaningless.(Lumberjack & Special Referee)

- We also need a code to enable 'Vacant' superstar so we can dummy out some unneeded superstar
- And a joker code.
- Somebody managed to put the 'Special Referee' match in Story Designer for the Xbox and you could play as a ref.Last time I see it was on Youtube.
Maybe someone with PCSX2 or could debug PS2 in real time (PS2RD /w ethernet cable) help?
