First of thanks for the help buddy. My Problem is not the compress thing the main Problem is that the filesize of the rx3 file(s) gets bigger after edit and after inject in the data3.big also gets bigger filesize. I need a Methode to inject without changing the filesize of the rx3 file. The Ps3 controlls the filesize after start when its not correctly the Ps3 freeze. Can anybody help me out with a little hex editing on 3 files it would be great. I hope I hope Jenkey makes a Ps3 Support of his File Explorer. So my original file has 148KB (rx3) after decompress and inject my new texture i compress it again and my file have 138KB. Thats why my Ps3 freezes i think.
