Here's a site where you can draw cheats you may want from, all you gotta do is turn them into .pnach files.

How to turn the codes into a .pnach file/format, use a normal/regular text document.
When you make the patch (patches are what its called for the code inside the text document you are using), to make your .pnach file, you should use omniconverter or PCSX2CE (You cna find these two programs from here

Read what this guy has to offer first though as the cheats you might be looking for may already be posted, just click on the "S" link he's provided in his post to get the the S section of his post faster to find Suikoden V.
If you really need to make codes for Suikoden V, do the following.
1. Take the code you want to use that you can find from
http://cheats.codetwink.com/ps2/view/5567/
2. Copy the code you want to convert to a .pnach format, and paste it into either omniconvert or PCSX2CE
3. The codes you find on that site need to be converted to Raw, to do this, there are options at the top of omniconvert, select Input and select Codebreaker V1 if it isn't already.
4. For the option Output on onmiconvert select Standard Raw.
5. Now, on the empty page on the left side of omniconvert paste the code you found from the site.
6. Click Convert at the bottom.
7. Now, copy the code that comes out on the right side, and open up your text document, and paste it.
(Note: Look here for how to structure your .pnach files as they are more informative than I am.)
8. Codes you put into the text document should look somewhat like this (See example below)
Example:
comment=Patches Developed By Trueshothaze
//Al Bhed Translated
patch=1,EE,20319FF0,extended,03FFFFFF
9. The 2 in my example (20319FF0) is ranged from 0,1, and 2. Something better explained here if you have the patience to read it all

10. To make your .pnach file when you are finished, highlight File at the top of your text document, and click "Save As"
11. Change the "Save as Type" from "Text Documents" to "All Files".
12. Now, name the file the CRC you found "E857CCF8" If you do not do this then the cheats will not work.
13. Make sure to add the ".pnach" to the name. (it should read "E857CCF8.pnach")
14. Now you're basically done, all you need to do is put it into your cheats folder you can find from Programs list in your Local C:// and you're done.
EDIT: Please re-read from 9. I accidentally posted the wrong link, the link I just replaced is now the correct one that explains .pnach files better than me.
