Porting Test Drive II from SNES to PC, Part 39: Closing the No-Opponent Handoff Into 02:9016

This checkpoint closes the last front-end ambiguity in the SNES Select Opponent flow. The fourth slot was already structurally solved as the stopwatch / clock path. What remained open was whether that path actually promoted into the same downstream gameplay corridor as the regular rival-car choices, or whether it diverged somewhere after 01:BE43 . What is now recovered A callback-relative probe keyed to the first live 01:C1D2 hit, plus a later be43+17-22:start confirm, now recovers the no-opponent path organically through: L00C20B -> 01:C1D2 -> L00BE76 -> 01:BE43 -> L008B87 -> 01:902D -> 01:9111 -> active_main = 02:9016 The important part is that this is not a forced callback lane. It is an organic input-driven path recovered from boot with timing tied to the live callback surface. The state difference survives the shared handoff The regular rival baseline and the no-opponent clock path now reach the same later corridor at the same timestamps, but they do not collapse to the same state
