LEGOPATCHER

Software emulator of the LEGO Dimensions Toy Pad for PS3 and PS4. Pick characters, vehicles and gadgets in the app and they appear on the console instantly — no physical portal and no real figures.

Cross-platform .NET MAUI app for Windows, Android and iOS.

Features

• Place, move, swap and remove figures across all 7 pad spaces.
• Live light mirror: the app shows each panel (left / center / right) lighting up with the colors the game drives, following the real pad's shape.
• Auto-saved builds: vehicles and gadgets you build in-game are captured and saved locally, so they show up already built next time.
• PS3 and PS4 support, selectable in the app.
• English and Spanish UI, switchable at any time.

How it works

A small plugin runs inside the game and impersonates the real USB Toy Pad, so the game thinks a portal is connected. The app never talks to the game directly — everything goes through FTP:

1. A figure is represented by a 180-byte NFC tag dump (.bin).
2. Each of the 7 pad spaces maps to a file (figure1.bin … figure7.bin).
3. To place a figure, the app uploads its .bin as that space's file. To remove it, the app deletes the file. The plugin watches that folder and reports the change to the game as if a real figure was tapped.
4. The plugin also writes a small leds.txt mirror with the panel colors the game is driving; the app reads it over FTP to animate the on-screen pad.

Nothing about the figures leaves your device except this local FTP transfer to your own console. Figure .bin dumps are game content and are not distributed — each user imports their own (see Import figures).

Console layout and FTP

	PS3	PS4
FTP server	webMAN MOD	GoldHEN FTP
FTP port	21	2121
Figures folder	/dev_hdd0/tmp	/data/toypad_emu
Per-space files	figure1.bin … figure7.bin	same
LED mirror	/dev_hdd0/tmp/leds.txt	/data/toypad_emu/leds.txt

What "Install" does

The Install button uploads the plugin (and anything else the console needs) over FTP, fully automatically. You don't copy files by hand.

PS3 (Install PS3)

1. Uploads the plugin toypad_emu.sprx to /dev_hdd0/tmp/toypad_emu.sprx.
2. Backs up the game's original executable once: /dev_hdd0/game/BLUS31473/USRDIR/EBOOT.BIN → EBOOT.BIN.original (skipped if a backup already exists, so it never overwrites your original).
3. Uploads the patched EBOOT.BIN in its place. The patch makes the game load the plugin on launch.
4. Restart the game.

To revert, delete the patched EBOOT.BIN and rename EBOOT.BIN.original back.

PS4 (Install PS4)

1. Creates /data/GoldHEN/plugins/ if missing.

2. Uploads the plugin toypad_emu.prx to /data/GoldHEN/plugins/toypad_emu.prx.

3. Registers it in /data/GoldHEN/plugins.ini under the game's section, adding this line (only if it isn't there yet — your other plugins are kept):

   [CUSA00935]
   /data/GoldHEN/plugins/toypad_emu.prx

4. Creates the figures folder /data/toypad_emu/.

5. Reboot or reload GoldHEN, then start the game.

Requirements

	PS3	PS4
Jailbreak	HEN 4.91+ or CFW	GoldHEN (Plugin Loader)
FTP	webMAN MOD enabled	GoldHEN FTP enabled
Game	BLUS31473 (US), updated to v1.22	CUSA00935 (US), updated to v1.23

The plugin and EBOOT patch target the US game IDs above. Other regions are not supported out of the box.

Usage

1. Pick your console — asked on first run, or use the Mode: PS3 / PS4 toggle in the toolbar.
2. Import figures — load your Dimensions.zip containing the NFC dumps (.bin) organized into Characters, Vehicles and Gadgets folders. Files stay on the device and are never uploaded anywhere.
3. Connect — enable FTP on the console and enter its local IP (and FTP user / password if you set one). The app uses port 21 for PS3 and 2121 for PS4 automatically.
4. Install — tap Install PS3 / Install PS4 once. This does everything in What "Install" does. Then restart the game.
5. Place figures — drag a figure onto a space, or tap a space then a figure. Drag between spaces to move or swap; tap a filled space to remove.

Vehicles and gadgets

They appear generic (blank) until built, just like real figures. Build one in-game, then remove it from the pad or tap Sync — the app downloads the built tag from the console and saves it over your local file, so it shows up complete next time. Works on both PS3 and PS4.

Languages

The UI ships in English and Spanish. The language picker appears on first launch, and you can switch anytime with the EN / ES button in the toolbar (your choice is remembered).

Build

Local (Windows):

dotnet build -c Release -f net10.0-windows10.0.19041.0

Other platforms build in GitHub Actions (see .github/workflows/build.yml): Android on the Ubuntu runner, iOS on the macOS runner. The .ipa comes out unsigned (an Apple certificate is required to install it). Tagging a release as vX.Y triggers the release job, which publishes the APK, IPA and Windows build.
