010 - can't hold
001 - can't throwed

other

3F - Item is cannot be thrown ...
7F - Item is cannot be hold ...
9F - Item can't be registered/checked ...

example :
all berry is can hold to pokemon, right? but you can't register that item or checked on bag menu. that why all of them is 100x xxxx, other item like potion is 9F (1001 1111), is same as berry, can be hold but you can't register that item.

0x09 - ???

0x0A - ???

*is seems on evolution item (14), repel+escape item (13), potion+healer+Sweet Heart(1), Honey (E), TM/HM (6) mail (7), some berry (8), key item ? (4), wait is seems have multple effect ...

0X0B - ???

00 - other
01 - Pokeballs (except park ball)
02 - some potion, healing item's, Sweet Heart
03 - Fluffy Tail

0X0C - ???

*is seems some specific on some item, i still need more data about this ...

0x0D - Grouping Item

00	None
01 - Battle/Equip Item
02 - Other Item
03 - X-item
04 - Pokeballs
05 - Mail

* actually is can filled any value.

* if item is have same Group, if you sort by Type, it will used 0x0F (? is seems like that)

0x0E - ???

*is seems set to 1 on almost berry item, gems and white herb. other is set to 0 ... , hm i sense is related to 0xF

0x0F - Effect id ? or for sorting purpose only?

*i will give detail about this offset later~

6. Recover/Remove bad status effect on pokemon (depend on effect id)

0x10 - Removing extra status effect

00	none
01 - Cures Sleep
02 - Cures Poison
04 - Cures Burn
08 - Cures Freeze
10 - Cures Paralysis
20 - Cures Confusion
40 - Snaps a Pokémon out of infatuation.
80 - Prevents stat reduction by opponents
3F - Cures any status ailment

it will accept multiply effect, like cures sleep + paralysis. 1 + 16 = 17 => 11 (HEX). pokeball is cures sleep and poison when battle end.

Pokeballs :

Master ball : not cure anything after battle end.
Ultra ball : cure sleep

Great ball : cure poison

Poké Ball : Cure Sleep and Poison

^ actually i don't know pokeball is cure a status after battle since i not care about that , but on my test well i was see my pokemon was cured from poison and sleep if i using pokeball but when i use ultra ball is still poisoned. is seems only on BW2 but idk.

the interesting part is on super rod, is cure poison. i was think if you catch pokemon using super rod and is get poisoned from your pokemon. it will healed after you catch that pokemon.

Ok i done solve a unkown value, yes is open new narc with unkown value too hehehehehe so forgot that is need more time to analyze...

My apologies, but as a total layman when it comes to this sort of thing, might you explain to me just exactly how that information is formatted and how I might use it to make some changes? I noticed the "battleuse = reader.ReadByte()" line in particular - would this mean that certain items could be made unusable during battle? A game with no in-combat Revives would be quite interesting, to say the least.

Kairi · June 22, 2011

So as far as data goes, you open up the file in question and the code just processes it. So think of yourself as the interpreter. ReadByte() means read 1 byte. ReadUInt16() means read 2 bytes. ReadInt8() means read 1 byte as an integer, and so on.

battleuse is a specific effect unfortunately. Most items just have 0 for defaults. itemcategory and itemtype might do the trick though.
