Battle effects: Seemingly nothing
Jumps to WRAM? No.

Hex: $55
Name: ち1 (B1F)

Battle effects: Same behavior
Jumps to WRAM? Yes, $D123
Can be used for ACE? Yes, i'll go into detail tommorow
Other notes: Essentially 8f for the Japanese releases
—————————————-
Hex $5B
Name: 6 (6F)

Can be used for ACE? No.
Other notes: None:
————————————-
Hex $5E
Name: 9 (9F)
Effects: Game crashes/hangs
Battle behavior: Same Behavior
Jumps to WRAM? Not directly, $F080
Can be used for ACE? No.
Other notes: None
————————————-
Hex $5f

—————————–
Hex $60

other notes: None
————————
Hex $61
Name: ち4 (B4F)

Battle behavior: Same behavior
Jumps to WRAM? Not directly, $EAAF
Can be used for ACE? No.
Other notes: None
———————————-
Hex $62
Name: みな (w m)
Effects: Dependant on data starting from $D0E1 onward
Battle behavior: Same behavior
Jumps to WRAM? Yes, $D0E1
Can be used for ACE? Sometimes. It's entirely dependent on the data at $D0E1 (wMoveStrings). Should the user be lucky, the data here creates a slide to Pokemon party data. See below for details.
Other notes: Don't try using this for ACE, 5f is an alternative that lands directly on Pokemon data
—————————————————-
Hex: $63
Name: (ws m)
Effects: Game simply hangs on the item menu
Battle behavior: Game crashes/hangs
Jumps to WRAM? Yes, but only during battle, and not directly. $F080

———————————–
Hex $66

Jumps to WRAM? No.
Can be used for ACE? No.
—————————————
Hex $67

Battle behavior: Behavior is interesting. Upon mashing a to escape the items menu, the battle will continue as normal, however you will not be able to see the screen. There can sometimes be brief periods in which the screen can be seen, but sprites are severely corrupted. After this, you enter a softlock-like state
Jumps to WRAM? No.
Can be used for ACE? No.

Other notes: Corrupted screen that appears after returning is rather interesting. I will attach it to this thread.

I have more, just allow me to secure some time. Also, the Japanese names are probably a little off. Apologies if they are.
[size=14pt]Getting Started With 5f[/size]
5 (known as 5f in the English releases) is a glitch item that executes code from $D123, which controls the number of Pokemon in your party. This essentially makes it a carbon copy of 8f from the English releases. Just like 8f, you will need a bootstrapper to use 5f practically. If you wish to direct traffic to the third bag slot, you may do so with:
// Exactly 5 Pokemon
Pidgey // 233 HP
Parasect
Raticate
Tentacool
Nidoran (male)
With this, the state of the registers will probably be:
af = 2300
bc = FFB2
de = 0001
hl = D2A6
"So what can I do with this" - You can now use 8f -like scripts. I can assure you almost no script from English R/B will work here due to a shift in data, but most codes can be ported.
Example "Get x255 Master Balls in first slot"
(Lemonade) x1
き34 (TM34) x162
き10 (TM10) x201
——————————————–
"So why do glitch items tend to jump to $F080" - For whatever reason, there is a jump instruction at $0038 to $F080. Since all rst vectors in Japanese Red/Green go to $0038, the code will end up at $F080 whenever an rst vector is hit.
