# verify-psp-save.sh - Save gate for the PSP port: a save outlives the
# program, beside it on the memory stick.
#
# SAVE (examples/save) counts its launches in SAVES/runs.dat. It is run twice
# under PPSSPPHeadless (scripts/lib/pspGate.sh) from the same folder on a
# private memory stick, PSP/GAME/SAVE, with every memory access checked as a
# PSP checks it; the PSP starts a program with its own folder as the current
# directory, so SAVES/ must appear there, and after the second run the count
# must be 2.
#
# Usage:   scripts/verify-psp-save.sh
# Requires: PPSSPPHeadless; build/psp/bin/SAVE (make psp).
