GGA: Recompiled

GGA: Recompiled

GGA: Recompiled is a native PC port of the Nintendo 64 game Goemon's Great Adventure (Ganbare Goemon: Derodero
Douchuu Obake Tenkomori), made by statically recompiling the game's code with
N64: Recompiled. It uses RT64 to render the
game, with enhancements such as high framerates, widescreen and up to 4 players.

Download the latest release here

This repository and its releases do not contain game assets. You need your own copy of the original game to play or build this project.

Version 0.1.0 is an early release. Worlds 1, 2 and 3 (with their castles and bosses) have been played from start
to finish. World 4 has not been tested yet: expect problems there, and keep a backup of your saves.

Supported ROM

Only the US release is supported:
Header code NGME
SHA-1 9f9e860816f9e2a68bb5f4f56086e0c7450c64d7

The Japanese and European releases cannot be played on their own, but the European one can add its languages (below).

French and German (optional, European ROM)

If you also own the European release (Mystical Ninja 2 Starring Goemon), the game can use its French and German
texts:
Header code NGMP
SHA-1 aadd1d7e943cbfa5496a370158b5f8fe17b06415
  1. Copy it, in .z64 format, to %LOCALAPPDATA%\GGARecompiled\ and name it goemon2.eu.z64 (next to your saves).
  2. Start the game: the title screen now shows Option, then Language, with English / Français / Deutsch,
    like the European release.

The dialogues, the font with accented letters, the title menu, the world map, the journal, the world title cards and
"Stage Clear" are translated. Without that file, nothing changes.

System requirements

  • Windows 10 or 11, 64-bit. (No Linux or macOS build yet.)
  • A GPU supporting Direct3D 12.0 (Shader Model 6) or Vulkan 1.2.
  • A CPU supporting AVX.
  • The Microsoft Visual C++ Redistributable (x64). Most PCs already
    have it; without it, Windows reports a missing MSVCP140.dll.

If the game crashes on startup, update your graphics drivers first.

How to play

  1. Download GGARecompiled-v0.1.0-windows.zip from the releases
    and extract it anywhere.
  2. Run GGARecompiled.exe.
  3. On first launch, the launcher asks for your Goemon's Great Adventure ROM. It is copied to
    %LOCALAPPDATA%\GGARecompiled\.
  4. Start the game from the launcher.

Settings, controller mappings, saves and mods are stored in %LOCALAPPDATA%\GGARecompiled\.

Features

  • High framerate: RT64 draws extra frames between the game's own, up to your monitor's refresh rate
    (Graphics > Framerate). Characters, carried players and scenery are interpolated.
  • Widescreen: Aspect Ratio Expand shows more of the world in 16:9. Scenery, objects and enemies appear and wake up
    at the edges of the wider view, the 2D backgrounds fill the whole width, and the HUD stays at the bottom like the
    original.
  • Up to 4 players: the 1P / 2P menu also offers 3P and 4P (greyed out without enough controllers). Players 3 and 4
    are real players, with their own HUD, lives, money and weapons, kept between areas and levels, on the world map too.
  • Controller Pak saves: saving and loading work like on the console (Controller Pak emulated on port 1).
  • Extra options (General tab):
    • Unlock Sasuke and Yae: all 4 characters can be chosen from a new game, so every player gets one.
    • Replay Castles: a beaten castle (shown in ruins on the map) can be entered again and played in full, boss
      included.
    • Draw Distance: Original or x2 on the sides, the fog stays the game's.
  • RT64 texture packs (.rtz) are supported through the Mods menu.
  • Extra graphics options: MSAA, downsampling, high precision framebuffer, texture filtering, output filter, 2D upscale.

Known issues

  • Only Worlds 1 to 3 have been fully tested.
  • Night-time enemies (levels played at night) have not been checked in widescreen yet.
  • French and German: tested mostly in World 1, German less than French. Some screens with drawn text, and texts outside
    the dialogues, may stay in English.

Reporting a bug

Open an issue with:

  • the version (for example 0.1.0) and your Windows version;
  • where it happened (world, level, area), how many players, and what you did just before;
  • what happened (freeze, crash, black textures, wrong sound…), with a screenshot if possible;
  • your graphics settings (Framerate, Aspect Ratio);
  • for a crash: run the game from a terminal opened in its folder with GGARecompiled.exe --log gga-log.txt, reproduce
    the crash, and attach gga-log.txt and gga_crash.txt.

Building

Building needs your own ROM: the game's code is disassembled from it, then recompiled. Windows only.
The repository does not build from a fresh clone yet (its libraries are not added as submodules); building instructions
will come in a later version.
