i can tell you, is too complex and must more analysis about ROM, i now research called component , i used both debuger, no$gba debugger and desmume 0.9.7 latest SVN Build debugger, is very hard to find, many value i not understand but is need a lot time to complete yet
maybe later release of kazorwar trainer editor, but is no battle editor! just pokemon trainer, and pokemon value, prize value, and type battle, but no mode battle (like dual player battle).
for change name you can use PPTXT.
i was complete list file of ROM Pokemon BW, so now i under working to translate ROM USA BW to my language is indonesia, and i change all resource into my language
please wait for someone to complete their analyze, thank you very much
