Tired of leveling up your final fantasy 8 characters manually? me too. Use this to make your life easier. Buy a programmable controller (interact sells a really old one for the playstation) and program it to move back and forth (<- and ->) then set that button to auto-fire so the character is always moving a little to the left and a little to the right. Now make sure that every single character in your party has the ST-J ability, and 100 drain to all of them. now strap a rubber band around the programmed button and the X button (or whatever your attack is). this should make your characters in battle attack and drain to replenish their life. and when they are out of battle, they will be constantly moving so you will always be getting in battle.
if you want to get a good boost on your stats, try and battle little, junction the stat bonuses from cactuar to your Squall, go to his room and tell everyone to leave, this will leave only him in your party. go to the training center and do the above trick (i like the place where joker usually stands). this should level up ONLY squall. when he is 99, get the other two people that u wanna level, equip one with cactuar, and the other person with the other GFs with the bonuses (i can't remember which ones have what bonuses) then make sure all characters are draining hp, and go to the training center and do the trick.
keep in mind that I didn't want any of my characters to die on my game, but if u don't care, just kill the character that you aren't using so they don't level without the bonuses equipped
this is done so you will get the max amount of bonuses for all of your characters, so you don't have to refine tons more STR ups, VIT ups, SPR ups, MAG ups than you really have to.
