Adds a new psx-beetleoracle build target that embeds beetle-psx-libretro
(mednafen PSX core) alongside the recompiled BIOS. Both execute the same
SCPH1001.BIN and advance in lock-step, enabling byte-level RAM comparison
via the TCP debug server.
New infrastructure:
- psx_oracle_backend.h: abstract oracle backend interface (init, run_frame,
get_ram, get_vram, get_scratchpad, read_byte/word, get_cpu_regs, sync_to_state)
- beetle_psx_bridge.cpp: libretro bridge with CPU register access via
PSX_CPU->GetRegister(), VRAM via GPU_get_vram(), scratchpad via ScratchRAM
- psx_oracle_cmds.c: TCP commands — find_first_divergence, emu_read_ram,
emu_read_vram, emu_read_scratchpad, emu_cpu_regs, emu_step, emu_sync,
emu_sync_press
- psx_oracle_stub.c: no-op stubs for non-oracle builds
- tools/oracle_diff.py: standalone Python RAM comparison tool
- tools/build_oracle.sh: build script for beetle-psx + oracle target
Also includes: SIO card probe diagnostic counters (mc_probes, mc_acks,
mc_cmds, tx_writes), enhanced dispatch miss logging with register context,
memory_get_ram_ptr() for oracle RAM comparison.
Build: cd beetle-psx && make platform=mingw_x86_64 STATIC_LINKING=1 HAVE_LIGHTREC=0
cd runtime/build && cmake --build . --target psx-beetleoracle
