Equip a minimal amount of materia to keep ur hp hi. counter attack is a must, cure (obviously), haste, i wouldn't rely on summons so don't use em. If u hav 2x cut i would use that instead of slash-all (u only get multiple enemies in the early battles n their easy to beat anyway, 2x cut can take the harder enemies down quicker). also, it sounds tedious but if u go into config and put the battle time down to as slow as it can, then the "timeX30" slot will do a minimal amount of damage. n like rita puffy sed, ribbon and ultimate weapons are a must. if ur using ultimate weapons, be sure to keep hp high (unless ur using yuffie, barret or cid. i wudn't use anyone else as cloud, yuffie's, barret's n cid's limits do awesome damage. leave yuffie on lv3 with doom of the living) ther r probly toher tips but these shud make it easy enough
