Erm you sure they're codebreaker?

They look half of raw and other half as swap magic type to me. Also which exactly is the code for mech modifier? My japanese almost not existing doesn't really help;o, I guess you ment one of the two codes:
Code:
機体変更
50xxxxxx 000002D8
00yyyyyy 00000000
x:変更後の機体アドレス
y:変更前の機体アドレス
機体アドレスは
3bc814h+2dch*機体番号
which was somewhere above the list of mecha then it's easy ~ already in raw, Y is the mech you want to replace with mech X. I assume japanese have some strange ways of saying we're dealing with hex;p, normally we use 0x before the number, they seem to use h after the number(just my guess;]), so the actual code would be
Code:
Replace mech
50xxxxxx 000002D8
00yyyyyy 00000000
Replaces mech Y with mech X
where addresses xxxxxx/yyyyyy is calculated on:
0x3bc814+0x2dc*mech number
soo for example we have a mech number 5 and want to replace it with mech number 10 we would get
yyyyyy = 0x3bc814+0x2dc*5 = 0x3BD660
xxxxxx = 0x3bc814+0x2dc*5 = 0x3BF5D4
so with this example code would look like:
503BF5D4 000002D8
003BD660 00000000
soo in pcsx2
patch=1,EE,503BF5D4,extended,000002D8
patch=1,EE,003BD660,extended,00000000
but frankly code type 5 ~will probably not work under pcsx2(never really had an use for it to check through

) meaning the code can be useless and you would have to copy some memory manually using a program like cheat engine or write some script or program to do it for you. Basically keeping the example you would have to copy 0x2d8 bytes from 0x203BF5D4 to 0x203BD660.;p The replaced mech would pretty much disapper from the game as I can guess so this code sucks anyway.;o
Maybe you ment this one:
Code:
ジェネハロ
ハロの能力強化(復号化状態)
2039AEA8 xxxxyyyy xxxx=HP yyyy=移動力(増やしたい数値の4倍)
2039AEAC xxxxyyyy xxxx=装甲 yyyy=EN
2039AEB0 wwxxyyzz ww=射程 xx=クリ率 yy=命中 zz=運動性
2039AEB4 wwxxyyzz ww=移動タイプ xx=EN回復(%) yy=HP回復(%) zz=01で分身
2039AEB8 wwxxyyzz ww=特殊能力 xx=出撃時気力+ yy=バリアの種類 zz=地形適応 08で全てS
0039AEBE 000000xx xx=コスト-
Then it's even easier, also already in raw, just need to be filled with some data you type in manually there in hex for example if xxxx is hp then if you want like 9999 hp launch windows calc in programmer mode or whatever calc that can convert decimal to hex and get your 9999 in hex which is 0x270F so there you go, xxxx value for you;p. Frankly I don't understand half of the other japanese in there even with an automatic translation(or maybe especially with?

) so just fill it with whatever you need remembering you have to put the value in hex and add formatting, it only writes some values, so it should work just fine in pcsx2. Oh and if that's not clear if the value takes 2 places you can use value from 0 to 255 only;p, if it has 4 places, it's from 0 to 65535. Setting everything on max would just look like that:
Code:
patch=1,EE,2039AEA8,extended,FFFFFFFF
patch=1,EE,2039AEAC,extended,FFFFFFFF
patch=1,EE,2039AEB0,extended,FFFFFFFF
patch=1,EE,2039AEB4,extended,FFFFFFFF
patch=1,EE,2039AEB8,extended,FFFFFFFF
patch=1,EE,0039AEBE,extended,000000FF
But it could as well look bad in game especially if normally such values aren't possible(it could even glitch some graphic on the stats in game;p) so better set those values to some nicer numbers ie:
Code:
patch=1,EE,2039AEA8,extended,270F270F
patch=1,EE,2039AEAC,extended,270F270F
patch=1,EE,2039AEB0,extended,63636363
patch=1,EE,2039AEB4,extended,63636363
patch=1,EE,2039AEB8,extended,63636363
patch=1,EE,0039AEBE,extended,00000063
which would set HP and EN to 9999 and the rest of stats to 99 each. Don't have the game to say it's alot or too little through;p.
Oh and one quite IMPORTANT thing;p, if you make your pnach file with kana, kanji or any other non latin special signs, make sure you save it properly as unicode, otherwise pcsx2 can have some problems reading the file.
