Marchwind 64 is an unofficial native recompilation project for Super Robot Wars 64. It runs natively on Windows, macOS, Linux, Steam Deck and Android, with full English and Chinese translations and widescreen support, plus an optional HD art pack.

Requires your own Japanese ROM (Super Robot Taisen 64, Rev 0). Neither this repository nor the downloads contain any game data. See About ROMs.

Original and HD graphics

Original · 4:3	MARCHWIND 64 · HD widescreen

Left: the original 4:3 view, with N64-resolution portraits and maps. Right: Marchwind 64 with the HD pack, showing redrawn portraits and world map in 16:9. Switch between original and HD art at any time in game; both use the same saves.

Interface and control updates

Built on the N64 original, with updated screens, full translations and control improvements, plus individually selectable bug fixes. All images below are in-game screenshots.

Dialogue reader

All dialogue is re-typeset in a high-resolution font. Each line runs continuously and is paged to fit the text size, avoiding page breaks mid-sentence. Earlier lines can be reviewed at any time, and auto-play, fast-forward and skip each have their own control, with the current reading mode and controls shown along the bottom of the screen.

• Review the last 256 lines, coloured by speaker
• Four auto-play speeds; text size from 10 to 18
• Fast-forward and skip work as in modern Super Robot Wars games: hold to fast-forward and let go to stop; skip runs through the whole scene to the next choice or battle, with the same result as reading every line
• Switch language or check the original Japanese at any time; the current line is re-typeset at once
• Dialogue is stored as plain text files you can edit yourself

Modern SRW screens and controls

The pre-battle screen is redesigned in the style of modern Super Robot Wars games: damage, hit and critical rates for both sides appear side by side with shield and barrier effects, and spirits, weapon selection and the battle animation toggle are grouped below. The tactical map gains the shortcuts modern entries have too.

• While choosing a destination, jump straight to the farthest reachable squares
• L1/R1 step through your units, L2/R2 through the enemy’s
• Stop a battle animation at any time; the result is calculated normally
• The original screen is also available in settings

In-game settings

Adjust language, original or HD graphics, aspect ratio, full screen and interface size during play. You can also toggle individual rule fixes and remap keyboard and controller inputs.

• Open them at any time in game, or from the button at the bottom right of the title screen
• Three interface sizes: standard, large and largest

RetroArch filters and bezels

Use RetroArch slang shader presets (.slangp) directly for CRT scanlines, NTSC colour and more. At 4:3 you can also add a RetroArch bezel; its transparent window lines up with the picture by itself. Both are in Options → General.

• Nine common presets included, such as crt-lottes, crt-geom, zfast-crt (for handhelds), ntsc-adaptive and xbrz-freescale
• Finds every slang shader of an installed RetroArch; drop your own presets and bezels in the data folder
• Works on the original 240 lines (closest to a CRT), 480, 960, or the window’s resolution
• Only the game picture and dialogue are filtered; the options window, notices and the bezel stay sharp
• Filters run on macOS and Linux/Steam Deck; not on Windows yet

_{Bezel: tv-integer from RetroArch’s own overlays (libretro/common-overlays, CC BY 4.0). Filter: crt-lottes at 480 lines. The game ships with no bezels.}

Library: 353 units, 293 characters

Organised by series, with unit stats, terrain ratings, weapons and their fully upgraded power, upgrade caps, and each pilot’s growth, spirits and skills. All entries come directly from the game data.

• Open it from the title screen or during play
• The same Library is on the website

Battle Viewer

Choose the attacking and defending units and pilots, set the weapon, the defender’s reaction, the damage and the scene, then play the full battle animation.

• View weapon animations for every unit
• Plays the attacker’s theme, as in the original

Battles in HD

High-resolution art for units, cut-ins, portraits and backgrounds, with the original animation timing and camera work.

Bug fixes and optional rules

Each rule has its own toggle and takes effect immediately, using the same save format. Select “Turn all off” to use the original rules.

Original bug fixes — on by default. Corrections to calculation errors and omissions in the original.

• ESP: hit and evade use the actual skill level (the original always used 64)
• Holy Warrior: evade uses the actual level (the original always used 32)
• Limit: hit and evade, each combined with mobility, are capped by the unit’s limit
• Potential: corrected HP bands, with no bonus at full HP
• Potential: hit and evade bonuses halved, criticals unchanged
• Machine swap: the 3 weapons omitted from the table also retain their upgrades
• Holy Warrior: Hyper Aura Slash grows stronger with the level

Convenience and difficulty — off by default. Optional adjustments to upgrades, funds and battle difficulty.

• Raised upgrade cap: every unit can reach 15 levels
• Departure refund: returns upgrade funds when a unit leaves as part of the story
• Parts carry over: enhancement parts move with the pilot to the new machine
• Boss dummies: halve their uses or disable them

Graphics and interface — new or original. Choose the new or original layout for each screen.

• Pre-battle screen: new, HD original or original
• Intermission, hero selection and title menu: new or original
• Art: HD or original, switchable at any time
• Aspect ratio: fill the screen or keep 4:3
• Battle animations and autosaves: individual toggles

More features

• Runs natively. The N64 program is recompiled into native code, with graphics rendered by RT64. After installation, add your ROM following the setup instructions to start playing.
• Full text in three languages. Full English and Chinese translations alongside the original Japanese. Character, unit and weapon names follow common usage in each language.
• Extra save slots and autosaves. More save slots than the original, with autosaves at key points. Export cartridge saves for use with ares, Project64, RetroArch and other emulators.
• Widescreen without stretching. Supports screen ratios from 4:3 to 16:9. The original view stays centred while the scenery extends to the sides, filling the screen without stretching the image.
• Handhelds, phones, controllers. Automatically detects Steam Deck and uses its button layout with a large interface by default. On Android, touch controls show the buttons needed for the current screen, labelled with their functions, such as “OK”, “Fast” and “Next unit”.
• Optional HD art pack. The HD art pack is a separate download that works on every platform. The game uses the original pixel art without it; once installed, you can switch between the two at any time in game.

System requirements

Windows, the Steam Deck and Android are experimental. The graphics requirements are the same as other recompilations drawn with RT64; older hardware has not been tested.

Windows (experimental)

	Requirement

Graphics	Direct3D 12 (Shader Model 6.0) or Vulkan 1.2
NVIDIA	GeForce GT 630 (Kepler) or newer
AMD	Radeon HD 7750 or newer
Intel	Intel HD Graphics 510 (6th-gen Core) or newer

OS	macOS 14 or later
Processor	Apple silicon (M1 or later); Intel Macs are not supported
Graphics	Metal

	Requirement
OS	64-bit, glibc 2.35 or later (Ubuntu 22.04, Debian 12 or newer)
Graphics	Vulkan 1.2
GPU and CPU	Same as Windows
Drivers	Up-to-date Mesa or NVIDIA drivers

Steam Deck (experimental)

LCD and OLED models on an up-to-date SteamOS. It uses the Linux package; a script adds it to Steam, and it is played from Game Mode.

Android (experimental)

Processor	arm64 (64-bit)
Graphics	Vulkan 1.1
Recommended	Snapdragon 865, Dimensity 1080, Exynos 1380, Tensor G2 or newer, about 30 FPS

The game takes about 150 MB, and the optional HD art pack about 550 MB more. If the game crashes at start or freezes, update your graphics drivers first. Step-by-step instructions for each platform are on the install page.

Building from source

The repository contains no ROM, saves, extracted game data, generated game code, HD art or prebuilt application. Put your own Japanese Rev 0 ROM in the repository root as rom.z64 (its identity is in provenance).

On macOS (Apple silicon) with Python 3.11+ and the Xcode command line tools:

brew install python cmake ninja sdl2 freetype harfbuzz icu4c
make                                                  # toolchain, generated game code and the host
scripts/Play\ SRW64\ Native.command --language en     # play
