I didn't find this game's page so i'm dumping the information from this player that goes by the name Append Huang on Youtube:

1. transform weapon <--> ForceMetal. For example....begin from 18:10, I transform the "Thunder Guard" (Force Metal) to "X Buster MK3" by " put the Thunder Guard in the last slot (101th) manually" (and the X buster MK3 will appear in the first slot of main weapon) . This glitch only works in Japanese versions (both GC and PS2 works) - there's no 101th slot in English version.
2. duplicate weapon / FM: For example....begin from 10:00 It's a variation of the transform trick. if you equip a "X Buster", it will still occupy a slot in the main weapon slot even if the quantity is 0. Then try to put this weapon in the first slot in the weapon list, then equip the weapon (X Buster is already in the first slot and equipped by default), then move the corresponding Force Metal (Speed+10 with quantity 0) away from the last slot - then you will find the first slot in weapon list is empty now. Unequip the weapon will occupy that slot with quantity 1, then manually move that weapon to another slot, then move the corresponding Force Metal back to the last slot. Then, you will find two same weapons occupying two different slots, with quantity 0 and 1. Equip the weapon with quantity 1, then the one with quantiny 0 will become 255.
I tried to use these tricks many times in the walkthrouch. The most important part is to get Zero's Red Lotus Saber in Chapter 7 and multiple SFM Fragment B in Chapter 9, then all the remaining bosses in these chapters could be finished in very few turns.
The WR holder of this type of routes is gameOpoona with an IGT of 2:50:40.
