Create a custom CONFIG file Castlevania Curse of Darkness for ps2 classics on ps3

Hi forum, I was wondering how to make a custom config file for Castlevania Curse of Darkness (SLES-537.55), maybe this is not the right place to post this, but it is the best place if we are talking about ps2 emulation, the issue is that this game has serious problems that makes the game unplayable, for example the vases seem to be floating around and there is something like spiky poligons that appear in front of the camera sometimes that don't let to see nothing.

Here it is the information related to the emulation of ps2 classics: http://www.psdevwiki.com/ps3/Emulation#CONFIG_File there are config files for a couple of games and there are unnofficial config files too besides commands that are hexadecimal numbers on how to use them, I tried using some hexadecimal values and made some custom config files that never worke, if someone could help me I will be always grateful
