The advantage of a repack over a raw ROM is file size. A full PS3 Fight Night Champion dump is roughly 8–12 GB. A high-quality repack can compress it down to without losing gameplay data.
Ensure the repack is built around a stable version of RPCS3 or Xenia. RPCS3 generally offers better graphical scaling (allowing you to play in 4K), while Xenia often handles the physics engine with fewer tweaks.
Use only trusted sources (check r/CrackWatch or r/Piracy megathreads). Always scan the .exe with Windows Defender and Malwarebytes. Do not run the installer as administrator unless necessary.
