Checks / web (push) Failing after 19s
Private ROM checks / private-rom (push) Failing after 25m36s
Read the English 1.0 and Australian cartridges besides 1.1 (#84)
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.
