Majin Recompile

An unofficial Windows recompilation of Majin and the Forsaken Kingdom (Xbox 360).
Windows x64 · Direct3D 12 · European/PAL revision · Experimental community alpha

Majin Recompile uses ReXGlue SDK 0.10.0 and its Xenia-derived runtime to run recompiled game code on PC. This is a community project, unaffiliated with the original developers or publisher.

No ISO, original game assets, DLC, saves, shader caches or generated game C++ are distributed in the repository or source companion. You must provide the files from your own legally acquired, supported copy of the game.

The European/PAL Xbox 360 ISO was used for testing. American/USA and Japanese editions have not been tested. Acceptance depends on the executable revision, not the ISO filename.

This is the clean public source publication; the previous development history remains private. See PUBLICATION.md.

Download and play

Download v0.1.0-alpha.3 — Windows x64. Choose Majin-Recompile-v0.1.0-alpha.3-Windows-x64.zip to play. Developers should also download the matching Sources.zip, which includes the patched SDK and pinned dependencies; GitHub's automatic source ZIP contains only this project.

1. Extract the entire Windows ZIP to a short, writable folder on your local SSD, such as C:\Games\Majin.
2. Double-click Majin FK Launcher.exe. No manual terminal commands are needed; the Windows launcher currently uses PowerShell internally.
3. Choose Import ISO for your own uncompressed supported Xbox 360 ISO, or Browse to extracted data containing default.xex and finalizedXBox360.
4. Start with 1x Native (720p), Original frame rate and Default rendering. Use ROV Compatibility if Default loses the image, as observed on the tested Ryzen 5 5500U.
5. Select Controller or Keyboard + mouse (test) and click Play. For the optional timing patch, select 60 FPS (test). Esc opens the quit confirmation; Enter opens the in-game pause menu in keyboard mode.

If a Microsoft runtime DLL is missing, install the Microsoft Visual C++ x64 Redistributable. Windows x64/D3D12 is the current release platform. Linux/Vulkan is planned.

Alpha.3 refreshes the launcher background with the owner-supplied scenery-only image. The game, GPU and audio binaries are the same ones tested for Alpha.2.

Features and current limits

• Original / 60 FPS (test): an opt-in 60-FPS cap and timing changes, with Original retained as the default. Prerecorded movies keep their original cadence. This is not frame interpolation or a universal 60-FPS guarantee.
• Default / ROV Compatibility: separate rendering choices and persistent shader caches. ROV restored missing images on the tested 5500U; it can cost performance and is a compatibility option rather than a low-end performance preset.
• Resolution and window options: decorated window/fullscreen, Original/FXAA and selectable draw scaling. 1x is the 720p base; 2x/1440p remains experimental, with an unscaled-resolve caveat. Internal 1080p is unsupported and 4K is unvalidated. Window/output resolution is a separate setting.
• Controller and keyboard/mouse input: an 8BitDo controller was play-tested; mappings and validation status are below. Xbox glyphs remain in-game.
• Local diagnostics: FPS/frametime CSV recording, a window-title FPS counter and bounded diagnostic export. Extra hardware details are opt-in; nothing uploads automatically.
• ISO import, save support and music recovery: supported-revision checks, portable saves and the existing menu/battle XMA recovery work.

Observed performance

Tested configuration	Result and scope
Intel Arc B580, Default, 1x/720p, 60 FPS mode, VSync On	About 7 minutes recorded; 57.96 FPS overall including loading/pauses, median of one-second measurements 59.99 FPS; save write and normal exit confirmed.
Intel Arc B580, Default, 2x/1440p selected, 60 FPS mode, VSync On	About 14 minutes without a recorded fatal error; 49.37 FPS overall, with stretches near 60 and sustained lower portions. Not constant 60 FPS at 1440p.
Ryzen 5 5500U, ROV, 1x/720p, Original, VSync Off	Previous/current build comparison was around 19 FPS in slower portions. Enabling the 60-FPS mode in an earlier test did not sustain 60 on this notebook.

These are limited owner play-tests, not a full campaign or cross-hardware benchmark. Metrics count guest swap intervals, including pauses/loading; they do not measure GPU execution time or prove unique displayed frames. See FPS_60.md and PLAYTEST_VALIDATION.md.

The current VSync option affects guest synchronization and some runtime waits. The 60-FPS cap stays active with it On or Off; the D3D12 presenter does not implement this switch as conventional monitor-synchronized VSync. See the explanation.

Controller support

The default backend is SDL3, which maps recognized gamepads to the Xbox 360-style state expected by the game. The Windows SDK also includes an optional XInput backend; the launcher currently uses the SDL default.

Controller / input family	Status in this project
8BitDo Ultimate 2 Wireless	Owner-tested. Recognized by SDL in the collected runtime logs and used for gameplay.
Xbox / other XInput-compatible controllers	Available through the runtime's SDL/XInput paths; individual models, connection modes and features are not all validated.
PS4 DualShock 4 / PS5 DualSense	SDL has PlayStation gamepad types, but these controllers are not yet play-tested in Majin Recompile. Recognition is not a guarantee of full project compatibility.
Other SDL-recognized gamepads	Compatibility depends on the device, Windows drivers and mapping. Please report the model and connection mode when testing.

For 8BitDo devices with several modes, an Xbox/XInput-style layout makes the game's Xbox prompts easier to follow. USB/Bluetooth/receiver modes and vibration features should not be assumed equivalent without testing. In-game prompts remain Xbox icons for all devices.

SDL references: gamepad types, recognized gamepads. The PlayStation labels below are positional references, not a claim that a PS4/PS5 controller was tested.

Controls

Select Keyboard + mouse (test) in the launcher to enable this profile. Mouse input emulates the right stick; it is not a native mouse-camera rewrite. The launcher also shows the command guide and sensitivity setting.

Action / game input	Xbox-style controller	PlayStation position reference	Keyboard / mouse
Move	Left stick	Left stick	W / A / S / D
Camera	Right stick	Right stick	Mouse / I / J / K / L
Jump / confirm	A	Cross	Space
Run / dash	Hold B + movement	Hold Circle + movement	Hold Shift + WASD
Interact / collect / back	B	Circle	E
Attack	X	Square	Left mouse
Roll	Y	Triangle	R
Crouch	LT	L2	Hold Q
Command Majin	RT	R2	Right mouse
Throw mode	LB	L1	F
Ability	RB	R1	C
D-pad	D-pad	D-pad	Arrow keys
Left stick click	LS	L3	V
Right stick click	RS	R3	Middle mouse
Pause menu	Start / Menu	Options	Enter
Map / Back input	Back / View	Share / Create position	Tab
Quit confirmation	Runtime action	Runtime action	Esc

Actions are contextual. E and Shift both send B: Shift provides a convenient running binding, while E remains available for interaction/back; either can trigger another B action in a different context. The game's X + A combination maps to left mouse + Space. See KEYBOARD_MOUSE.md for modifier behavior, validation and limitations. In-game keyboard glyphs and remapping are planned after the Alpha.

Saves, cache and updating

Saves belong to this extracted copy, under private/runtime/user. Back up that folder before updating, moving or deleting the app. Extract updates separately and keep the previous copy until your save loads correctly. This portable Alpha has no installer/uninstaller or automatic save migration.

Caches are reused under private/runtime/cache, separated by Default/ROV, Debug/Release and scale. Original and 60 FPS share the cache within the same rendering configuration. First visits can compile shaders and stutter. Changing rendering path does not move saves. A private USB test kit containing an ISO, data or saves is not a redistributable release.

Known issues

• Stretched pixels at pause/status-menu edges and noisy rain/particle effects remain.
• Default can lose the image on some integrated GPUs. ROV may help at a performance cost.
• Cutscene audio/video drift, stutters and perceived input latency were observed on the notebook; full cinematic timing is not certified on other systems either.
• Draw scaling can report an unscaled 1280x720 swap/resolve source. Selecting 2x does not certify native 1440p throughout every rendering stage.
• Deeply nested installs were involved in earlier shader-cache startup failures; long paths remain a hypothesis, not a confirmed root cause. Prefer a short local SSD path.
• Full campaign, all input combinations/controllers, 4K, Linux/Vulkan, internal 1080p and DLC import remain unvalidated or unimplemented.

Diagnostics and feedback

After reproducing a problem, close the game and double-click Collect Diagnostics.cmd. It collects bounded runtime logs/settings, frame metrics and relevant Windows failure events into reports. The active GPU already appears in runtime logs; extra CPU/RAM/GPU/driver details require opt-in. It excludes ISO, game data, saves and shader-cache contents, and does not upload anything. Review the ZIP before sharing.

Include the package version, checkpoint, steps, controller model/mode, graphics settings and whether OBS/monitoring was active in a GitHub issue. See PRIVACY.md, PERFORMANCE_DIAGNOSTICS.md and CONTRIBUTING.md.
