PRET's crystal and crystal_au builds reproduce both retail cartridges, and every label the profile pins keeps its address in all three; check:reference now verifies that when the rebuilds are present. The revision comes from the header. Revision 1.0's Battle Tower draws only the first 21 trainers and picks its texts' gender from the name's sixth character, checked against each cartridge. A native backup imports across the three, which share every map, event and object. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
