- Modify the svcMapProcessMemoryEx svc so that it takes an extra flags argument. This change was made in a way that shouldn't break existing plugins or applications. - Add MAPEXFLAGS_PRIVATE flag, which maps the specified memory as PRIVATE instead of SHARED. - Allow plugins to be mapped with PRIVATE memory instead of SHARED with a flag in the .3gx header. This allows plugins to use socket and http services without additional hacks. --------- Co-authored-by: LittleCube <littlecubehax@gmail.com>
