Well I read around and apparently, official GC games can not be booted once CIOSCORP is installed.
This is partly true. I installed CIOSCORP myself and my official GC games could not be booted from the disc channel. However, I did manage to boot them using emu_kidd's GCBOOTER that was released a while ago. Even though this is not an ideal fix, it does the job.
