Codebreaker for ps2 nowadays means one of the two encryptions, through also raw codes are posted as "codebreaker" since it's also able to use them, the codes you posted are encrypted in codebreaker 7+ version means you need to convert them to raw before you'll be able to use them in pcsx2;p.
You can find both tools which makes the conversion ultra easy in
this thread. Anyway try doing it yourself untill you get such result:
Code:
//Max Gold
patch=1,EE,205686F0,extended,000F423F
//Infinite Roulette Orbs
patch=1,EE,20568778,extended,01010101
^ which are correct, still doesn't mean they'll for sure work for you since you didn't post any info and afaik nobody here is reading minds, well not on the distance at least(most of the time codebreaker codes are for the US version if yours is different then well it'll probably fail;p).
Basically when using omniconvert make sure you set both input and output, input will usually differ, for those codes it was codebreaker 7+ like I mentioned already if you aren't experienced enough to recognize those codes by eye search the info on the site they were posted it, output you want for pcsx2 will always be unencrypted->standard aka raw. Note all codes can be converted correctly to raw and not all code types work in pcsx2, but for most cases that'll work just fine.
Also don't be scared to post link to external sites. As long as those sites aren't warez/porn related you're free to post links and that's typically useful with codes since nobody can say for sure you already didn't messed them;p. At least you wrote they're from codetwink, enough for me.
Codes you posted crash because while being encrypted pcsx2 still thinks they're raw since encrypted codebreaker looks similar and in such form they're totally messing your game logic.
Also there was some faulty pcsx2 version few revisions ago which could cause crashing by loading all pnach files if game CRC was not detected correctly(for some people it happens with full boot). Soo if you do use svn versions and not using latest, make sure to update it just in case.
