Many games work flat out ... Others don't. Some are rumored to be fixed by supplementing other suprx files into the sce_module folder (ux:app\PS12345). All have this same C2-12828-! error ... I've tried to fix 2 titles now to no avail. Must of tried about a dozen other vpks sce_module files and this is what I've found ... libface libfios2 libult... are primarily unchanged throughout releases but libc and libsmart seem to differ in file size across vpks. Also some VPKs have two steroid files ... Not sure what else I can try for these other than hoping vitamins next rls will work.
