1.Extract the ripkit folder (with winrar) & put your BBS0.DAT BBS4.DAT into the same folder(extracted with UmdGen) and run the Run_me.bat and follow the instrutions this will extract all the .tm2 .png .at3 .pmf.
2.Then downsample but keep the same name,but if the files are bigger it will not be added.(to downsample read the tutorials)
3.Run the Run_me.bat this will then inject the files back in!!(Put the new BBS0.DAT BBS4.DAT back in using UmdGen or WQSG_UMD_R31)
4.When you cso your iso it will be smaller!!
5.Make a ripkit!!!!!
many thanks to Gnie and skybladecloud for the tools

Plus heres a tool from Gnie to convert TIM2 to BMP and visa versa
A simple program that is able to convert TIM2 images to BMP back and forth, however it does not support the semi-transparent alpha channel. (if your image has one)
