+1.6.0-bacon21
+    Added TG5040 and TG5050 targets for TrimUI handhelds running NextUI
+        * TG5040 covers the Brick, Brick Pro and Smart Pro; TG5050 is its own
+          platform with a separate toolchain and sysroot
+        * Both reuse the existing SDL2 adapter set; no new adapter code
+        * SDL2 window now takes the panel's full mode on these platforms,
+          so the scaled grid is centred in the real screen
+
 1.6.0-bacon20
     Fixed MIDI muting
     Added MIDI chord command (MCHD)

 - **gp32:** place LGPT.fxe, lgptNew, and lgpt10k in \GPMM
 - **gp2x/caanoo:** place LGPT.gpe, lgptNew, and lgpt10k in the same folder (anywhere on your SD card)
 - **win/mac/\*nix :** everything should be in the right spot, just run the executable in \install\bin\ (for fullscreen run “lgpt.exe -fullscreen”)
+- **trimui (Brick / Brick Pro / Smart Pro / tg5050, NextUI firmware):** NextUI organises add-ons as "paks". Put the files in a folder called LGPT.pak under Tools/tg5040/ (or Tools/tg5050/) at the root of the SD card, alongside a launch.sh that runs the binary, then start it from the Tools menu. The package's INSTALL_HOW_TO.txt has a working launch.sh, including the LD_LIBRARY_PATH line these devices need to find their own SDL2.

+Installation (TrimUI Brick / Brick Pro / Smart Pro, NextUI firmware)
+===================================================================
+
+NextUI organises add-ons as "paks": a folder ending in .pak containing a
+launch.sh. Tools live in Tools/<platform>/ at the root of the SD card, and
+this build's platform is "tg5040".
+
+1. Make a folder on the SD card:   /Tools/tg5040/LGPT.pak/
+2. Copy into it: lgpt-tg5040.elf, config.xml, mapping.xml, custom_font.xml
+3. Add a launch.sh in the same folder:
+
+       #!/bin/sh
+       cd "$(dirname "$0")"
+       chmod +x ./lgpt-tg5040.elf
+       export LD_LIBRARY_PATH="/usr/trimui/lib:$LD_LIBRARY_PATH"
+       exec ./lgpt-tg5040.elf
+
+   The LD_LIBRARY_PATH line is required. /etc/ld.so.conf is empty on these
+   devices and /usr/trimui/lib is not on the default search path, so without
+   it SDL2 either resolves to whatever another pak happened to leave behind
+   or is not found at all. It must be the device's own SDL2: other builds
+   are known to fail on the Brick's unsupported SDL_GetDisplayDPI query.
+
+4. Put your samplelib/ and lgpt_* project folders next to the binary, or set
+   ROOTFOLDER in config.xml to keep them elsewhere on the card.
+5. Launch LGPT from the Tools menu.
+
+Controls
+--------
+D-pad navigate, A edit, B back, L/R modifiers, START play. SELECT and the
+menu button are deliberately unmapped.
