Nightmare Creatures es un videojuego de terror lanzado para PlayStation y Windows en 1997 y para Nintendo 64 en 1998. Fue desarrollado por Kalisto Entertainment y distribuido por Activision. El juego relata las aventuras de los dos protagonistas en diferentes periodos del tiempo que luchan contra el alquimista Adán y la Hermandad de Hécate, quienes están tratando de crear una raza de superhombres para que los sigan en sus planes. Por desgracia, en vez de superhombres, han creado una horda de monstruos para que los ayuden en su plan de conquistar el mundo.

RetComM Launcher
You can run this title standalone (release zip + the built-in recomp-ui Generate & Build flow), or manage installs, updates, ROM/BIOS wiring, and queued builds more intuitively with RetComM Launcher — the Retro Compilation Manager hub for self-compiling recomps.

<!-- /retcomm-readme-launcher -->Legal
You must own the original game. Disc images under disc/ are gitignored and
must never be committed. Retail BIOS dumps are not redistributed. This title
requires a legal SCPH-1001 BIOS dump. OpenBIOS is not a qualified route.
Project-owned files use GPL-3.0-only. This license does not cover psxrecomp,
recomp-ui, game data, generated retail code, artwork, names, or trademarks.
See THIRD_PARTY_NOTICES.md for the separate dependency licenses.
Default app icon: assets/psxrecomp.ico (and .png / .svg) — RetComM-themed controller mark from psxrecomp/assets/. Windows builds embed it via APP_ICON.
Optional box art under launcher_assets/img/ may come from
libretro-thumbnails
(Named_Boxarts); see BOXART_SOURCE.txt when present.
Quick start (dev)
git submodule update --init --recursive
./psxrecomp/tools/ci/build_emitters.sh
python3 psxrecomp/psxrecomp_cli.py generate \
--config game.toml --project-root . --disc disc/<your>.cue
cmake -S . -B build-release -G Ninja -DCMAKE_BUILD_TYPE=Release
cmake --build build-release --target psx-runtime
Zip prefix for CI artifacts: nightmare-creatures-recomp.
Symbols
Progressive map: symbols.toml → python3 tools/sync_symbols.py →
psx_symbols.h (PSX_FN_*). See psxrecomp/docs/SYMBOLS.md.
Framework pins
Submodule gitlinks (psxrecomp, optional recomp-ui, nested recomp-net)
are authoritative. framework_pins.txt is an optional scaffold snapshot;
release CI logs SHAs with record_pins.sh but builds whatever the gitlinks
resolve to. Bump submodules deliberately — do not float on main/master
in release CI.
+## About this project
These ports are developed by a hobbyist (a DevSecOps engineer, not a game programmer) with substantial AI assistance. What keeps that honest: every change is validated before it ships - boot gates, hardware-oracle A/B comparisons (Beetle/DuckStation), deterministic replay probes, and a shared findings registry that documents failures as carefully as successes. AI writes most of the code; the evidence discipline decides what survives. Bug reports welcome - expect them to be investigated the same way.
tl;dr AI writes the code, but I always test it myself before pushing

v0.1.1 three-platform candidate
This candidate targets Windows x64, Linux x64, macOS ARM64, and macOS x64. These setup packages require your legally owned game disc and a supported regional retail BIOS. They remain unpublished until their exact package tests and release authorization pass.
