DMC5 Turbo Mode — PS4 (GoldHEN plugin)

A GoldHEN plugin that brings the PC Turbo Mode Injector speed modifier to Devil May Cry 5 on PS4: a live global game-speed multiplier with in-game controller adjustment and on-screen feedback.

This is an unofficial PS4 port of the turbo mode from Turbo Mode And Character Swapper by Naxshe on Nexus Mods. Huge thanks to the original author — this project would not exist without their work. It is not affiliated with or endorsed by them.

• Live speed control: 1.00x – 2.00x, applied within 10 ms, no restart
• In-game controls: hold L3 + D-pad Right/Left to step by 0.05x
• On-screen feedback: PS4 notification shows the value and a slider bar
• Persistent: the chosen speed is written back to turbo.ini
• Runtime discovery: no hardcoded addresses at runtime (region/update tolerant)
• Fail-safe: if the game code does not match, the plugin leaves it untouched

Verified on DMC5 v1.00 (PS4).

Install

1. Copy DMC5_turbo.prx to /data/GoldHEN/plugins/.
2. Add the plugin to /data/GoldHEN/plugins.ini (keep your existing entries):

[CUSA08216]
/data/GoldHEN/plugins/DMC5_turbo.prx

3. Launch DMC5.

[CUSA08216] is the game's title ID — keep it exactly as shown. Only the .prx filename changed to DMC5_turbo.prx; the section is what tells GoldHEN to load the plugin for this game.

Requirements: GoldHEN 2.3 or newer with plugin loading enabled.

turbo.ini (optional)

The plugin works without it and defaults to speed=1.2. To set a starting speed, create /data/GoldHEN/plugins/turbo.ini:

[settings]
speed=1.2

Values: 1.0 = normal, 1.2 = +20%, 2.0 = 2x. The file is re-read every 5 seconds while the game runs, so FTP edits apply live. Hotkey changes update this file automatically.

Controls

Input	Action
Hold L3 + D-pad Right	+0.05x (hold to repeat)
Hold L3 + D-pad Left	−0.05x (hold to repeat)

Each change pops a notification:

DMC5 Turbo  1.35x  [###-------]

The game still receives the D-pad presses (typically taunts) — unavoidable when sharing the pad. The plugin only reads the controller passively through the handle the game itself opened; it never opens the pad on its own.

Compatibility

• DMC5 v1.00 — verified.
• Other regions / game updates — the plugin scans the game's executable for the reflection getter shape and identifies the speed field from the Application constructor defaults. Builds that share the engine code shape (typically regional discs of the same version) work without changes.
• Add one section per title ID in plugins.ini, all pointing at the same file:

[CUSA08215]
/data/GoldHEN/plugins/DMC5_turbo.prx

[CUSA08217]
/data/GoldHEN/plugins/DMC5_turbo.prx

If the scan finds no compatible code, the plugin logs no compatible getter code found and does nothing — it never writes through an unverified pointer.

Build

Requires the OpenOrbis PS4 Toolchain (LLVM 10+):

export OO_PS4_TOOLCHAIN=/path/to/OpenOrbis/PS4Toolchain
make

Output: DMC5_turbo.prx (fake SELF, ready for /data/GoldHEN/plugins/).

The repo vendors the GoldHEN Plugin SDK headers/helpers and crtprx.c (see THIRD_PARTY_NOTICES.md).

How it works

The PC mod continuously pins the engine's Application speed float. The PS4 build exposes the same field; this plugin finds it without hardcoded addresses:

1. Scan the main module's executable segment for the reflection native-getter shape:

   mov rax,[rip+slot]          ; singleton slot
   vmovss xmm0,[rax+field]     ; float property
   vcvtss2sd xmm0,xmm0
   vmovsd [rdi+0x38],xmm0      ; native return convention
   ret
   

   (SSE encoding is also accepted.) Every hit yields a singleton slot.
2. Wait for a slot to point at an object containing the Application constructor defaults: 1.0 at +0, 0.001 at +0xC, 60.0 at +0x18, 6000.0 at +0x1C. The matching offset is the speed field (0x280 on v1.00).
3. Pin that float to the configured speed every 10 ms.

On v1.00 the plugin scans 80 getter sites, resolves 11 singleton slots, and identifies the field at +0x280 at runtime.

If no getter is found, it falls back to the exact v1.00 profile only after verifying the v1.00 signature; otherwise it stays idle.

Logs: /data/GoldHEN/plugins/turbo.log and the GoldHEN kernel log.

Troubleshooting

Symptom	Check
Nothing happens	GoldHEN ≥ 2.3, plugin loading enabled, correct [TITLEID] section
No notification/hotkeys	Look for pad: adopted game handle in turbo.log
no compatible getter code found	Game build/version not matched by the scan
Wrong game version	Add its title ID section; if the scan still fails, open an issue with the eboot version
