If i'm not mistaken Part III's scans are the oldest ones, so its possible new scans for the whole part still aren't available

Aside from that, I believe the rest of the scans on Batoto for the other parts are in high quality

The group Invincible Trio is re-scaning Parts 4 and 5, while 5-7-8 are already good
