NOTES:
1: IF you are using this to make a PS4 Dynamic Theme, there is a limit on how big the "scene" can be, its 16MBs so this should be takken into account prior to starting work on any themes.
2: IF you are going to make a PS4 dynamic theme, pick a unused Title AND Content ID(UP0002-CUSAXXXXX_00-XXXXXXXXXXXXXXXX // CUSAXXXXX) to do this you edit the .sfo in sce_sys(sce_sys/param.sfo) you can do it with a hex-editor(i wouldn't recomend this method as it can new user to mess up and destory the sfo) or use orbis-pub-sfo.exe found in Fake_PKG_Generator the reason for this being if two different themes share the same ID's the last one installed will overwrite the one before it(most people don't want this to happen :D) if you don't know if a ID is taken, google it, it should show if anybody used it before.
