I prefer the AFC Club Competitions back when there is no AFC Cup/AFC President Cup, hence why i make a trio of file with the formats of AFC Club Competition before AFC Decided to split it.
1985-199x: 45 Team Qualifying Round (ALL AFC except Mariana and North Korea), followed by 12 team group stage and 4 team knockout.
199x-2002: Same as Above but with the group stage replaced by the 16 team knockout
2002-2003: 54 Teams Qualifying Round (STILL NO MARIANA AND NK), followed by 16 Team GS and 4 team KO
