Gemfire (SNES)

The second KOEI SNES title reversed — and the pass that exposed the trampoline bug in rot3k2-snes, forcing a full re-walk there.

The per-routine native JSR $3287 trampoline (body at +5), made profile-driven. This is the key engine finding, and the reason the ROTK2 SNES walk had to be redone — the same trampoline pattern was silently corrupting that title’s names.
Engine coverage: 218 + 48 opcodes, 82 syscalls, 88 native routines; modules root + command + comusr1/2 + comcmp-AI + settei + event + senzen/sensou/sengo + ending; plus a full data-walk.
Second cross-console pair (after ROTK2), so the portable-VM finding is checked twice, not once.
