Test #1: Can Gryz use Silentwave?
Tested with Phonon and Sweeping.
Yes, but Chaz is still in the animation.

Test #2: Can Destruct be used by Chaz, Wren and Rune in any order?
Tested with Destruct's number bit set to 03, and FF after one combination.
Yes, but Rika is still in the animation.

Test #3: Can order-sensitive techs have their order nullified?
Tested with Rune and Wren using Shootnstar in the wrong order.
Yes, but the rockets are fired from Rune's shoulders.

Test #4: How much can we manipulate equipment?
Tested with Chaz using monomate as a 1-hand multi-target attack.
Yes. No animation is shown.
Tested with Chaz using monomate as a 2-hand melee attack.
Yes. Animation is very plain and there is no audio.
Tested with Alys using boomerang as 2-hand melee attack.
Game freeze.
Tested with Chaz using boomerang as 2-hand melee attack.
Yes. Relatively normal animation and appropriate audio.
Tested with Alys using boomerang as 2-hand multi-target attack.
Game freeze.
Tested with Chaz using boomerang as 2-hand multi-target attack.
Yes. No animation, appropriate audio.
Conclusion: although anything works as long as the character has an animation available for it, in hacks it would be best if only weapons were hacked as weapons. As long as the character has an animation, they are interchangeable.

Test #5: Can supplementary attack effects work on other equipment?
Tested with leather cloth having a very powerful stun effect attached.
No, this doesn't work.

Test #6: Can damage be a supplementary attack?
Tested with dagger, huntknife and boomerang with very powerful supplementary attacks at value 01.
No, this doesn't work.

Test #7: Can paralyze be used as a supplementary? Does paralyze affect enemies?
Tested with dagger, huntknife and boomerang with very powerful supplementary attacks at value 1C.
Yes. Paralyze seems to stop monsters for one round, making it worse than sleep against enemies. I put the element to 0E and proceeded to kill Igglanova without it taking an action.

Test #8: The names at 2a8da0. What's the deal?
Tested by changing "Chaz" to "Kyle".
No obvious effect at all.
D'oh, one of these two took effect upon starting a new game.
I changed it to "Bort". Changed on battle and status screens, but not in the dialogue. 280cd0 is still set to Kyle, but the game still refers to him as Chaz.

Test #9: The names at 280cd0?
Tested by changing "Chaz" to "Kyle".
Nothing. What the hell?
D'oh, one of these two took effect upon starting a new game.
See the above test. 280cd0 is not used.

Test #10: The enemy names work though, right?
Tested by changing "XANAFALGUE" to "Kyle      ".
Yes, as unflattering as it is.

Test #11: Enemy skill 70.
Tested by filling "Kyle      "'s slots with 70. He proceded to crashlessly maul Hahn with it.  No plot effect. It appears as a regular attack.

Test #12: Enemy skill 54.
Tested by filling "Kyle      "'s slots with 54. Two of them proceded to crashlessly maul the gang with it. No plot effect.

Test #13: Enemy skill 6C.
Tested by filling "Kyle      "'s slots with 6C. Two of them proceded to crashlessly maul the gang with it. No plot effect. It's not very strong when used by Kyle       either.

Test #14: Enemy skill 67.
Tested by filling "Kyle      "'s slots with 67. Two of them proceded to crashlessly maul the gang with it. It IS obviously the black wave, and does extreme damage. No plot effect.

Test #15: Enemy skill 68.
Tested by filling "Kyle      "'s slots with 68. Two of them proceded to crashlessly maul the gang with it. It IS obviously the black wave, and does extreme damage. No plot effect. Geez! :P

Test #16: Enemy skill 6B.
Tested by filling "Kyle      "'s slots with 6B. Doesn't make a magic barrier. Acts as a normal attack.

Test #17: Does changing a PC's starting level affect their stats?
Tested by making Chaz's base level 2 and Alys' base level 8.
No, they are still functionally level 1 and level 7 respectively. However, their next level is level 9, meaning they require more experience. Level acts as the increment at which the game looks for the next experience total needed.

Test #19: Is the real level data at 2856b1 or 2a3a42?
Tested by improving Chaz's stats at the first offset and Hahn's at the second.
It is the first.

Test #20: Are your stats really set to the level value?
Determined by previous test; when Chaz levelled a second time, he had negative stat increases.

Brose: Can we make it single target? Yes.

Deban: Can we make it do "has slept!"? Yes.
Deban: Can we make it target enemies? Yes. Goodie.
Deban: Can we make it have the opposite effect? YES! Effect 04 is in this game although unused, and it does defense down.
Deban: Can we make it reduce the target's magic defense? No. 05 doesn't seem to do anything.
Foi: Can we give Foi a stunning effect? No. When its effect is changed, it still does damage normally.
Recover: Can we make it multitarget, androids only? Yes, using target value 37. The android that isn't using this skill is not featured on the animation, but it works.
