You don't paste tiles as BOBs in AMOS. It's too slow. Instead you paste them as Icons. Opaque blitting is more than twice as fast as transparent blitting with a mask.
PM me your email and I'll send you the TOME extension and scanned manual.

Never mind, I'm reuploading it to the Amos Factory now.

It's up! And I spent extra time converting the manual scans to a PDF so it takes only 2.5 MiB.
