# retroDE_ps2 — DobieStation headless trace runner build
#
# Links against the libCore.a produced by the DobieStation build in
# third_party/DobieStation/build/. Requires that build to exist first:
#
#   cd ../../../third_party/DobieStation
#   mkdir -p build && cd build && cmake .. && make -j$(nproc)
#
# Then from this directory:
#
#   make
#   ./trace_runner ../../vectors/bios/nop_sled.bin
#
# See also: trace_runner.cpp header comment.
