It's pretty common for games to store different things in same places during different parts of gameplay, it's also not soo rare for games to change place they store it's data from time to time. In the first case you'll have to enable cheats only in correct place where you initially found them, so no, you can't simply enable cheats in pcsx2 and forget about it keeping it activated forever. If it's the second case you'll have to either find a way to patch the game system to make it store your data always in same place in memory, find the cheat each time anew or write yourself a trainer which would do that.

Don't use the cheats if you're facing problems.But if you don't mind can you attach your pnach file here.I'll have a look at it and see what's wrong

Ummm don't use word;], you either want to change that for byte or do it like that:

still the same problem, the log keep telling about that EE and TLB miss or something like that

Well then my first post was probably right. The game stores different things under same adress when you're playing it now in compare to when you found the cheats;].

Also althrough it wasn't the case I should explain why the format was wrong.
Code like this:
patch=1,EE,215b87f8,word,00000001

Will freeze 215b87f8 as 1, but will also freeze 215b87fA, 215b87fC and 215b87fE as 0's;] if there was other data there, it would break it. "Word" is the lenght type, basically it means you're patching 4 bytes, while it seems by looking at the value you probably wish to patch only one. To patch 1 byte you could write a "byte" there, but the way I used is more ps2-like, and should be preffered here.

Soo why changed code looks like that:
patch=1,EE,015b87f8,extended,00000001
? first letter of the adress in PS2 codes is actually "code type", by changing 2 to 0 I say it something like "patch only 1 byte", and by using the "extended" I just tell pcsx2 to detect cheat type based on it's code type.


edit:
And hell yeah, I noticed the code descriptions just now, the codes are probably correct now with proper formatting, but you are trying to patch ALL STAGES for ALL RACES in the same time? Obviously you should activate only one code for proper race and stage you're on.

hmm, so be it. i still don't get it

It's simple, the game stores loads of different data in big chunk around the adress you found it, it's different lenght for each stage and race that's why the adress is in different place for each of the case. But when one adress is correct, all others store different data and if you patch all of them at once, you're basically breaking the game. Conditional codes could help if you could also find an adresses storing for example stage number and race which wouldn't change, but that code type isn't working anyway(I think;p). Soo either use only one code at the time when you'll need it, or don't use pnach at all, couse it's bothersome to activate and deactivate if you have to do it often.
