# Headless UBER run for the PSP port: UBER's EBOOT.PBP under PPSSPPHeadless
# (scripts/lib/pspGate.sh), from a private memory stick, with every memory
# access checked as a PSP checks it -- an unaligned or wild access stops the
# run and fails it, naming the line -- until UBER's joeylog.txt says "press
# any key to exit". The log is copied to build/psp/bin/UBER/joeylog.txt.
#
# The stage is the generic chunky one, so the hashes must equal the DOS
# port's:
#   scripts/bench-psp.sh && build/tools/diffUberHashes tests/goldens/uber/dos.txt build/psp/bin/UBER/joeylog.txt
# The ops/sec are PPSSPP's emulated clock, which runs unthrottled: compare
# them only run against run.
