v0.4.2-testing — Minecraft Bedrock 1.2 for Miyoo Mini Plus

First public release. Testing quality — it has run on two consoles' worth of
Onion versions and one person's hardware, so treat it accordingly.

No game files are included. You supply your own Minecraft Bedrock Android
APK from your own Google Play purchase.

NOT AN OFFICIAL MINECRAFT PRODUCT. NOT APPROVED BY OR ASSOCIATED WITH MOJANG
OR MICROSOFT.

What this is

Minecraft Bedrock 1.2.20.2 running on a Miyoo Mini Plus, a handheld with no
GPU. Every pixel is drawn by Mesa's llvmpipe software rasterizer on two
1.2 GHz Cortex-A7 cores, and an EGL shim blits each finished frame straight to
/dev/fb0.

Performance, honestly

Measured in an ordinary generated world, standing still:

	stock 1200 MHz	1800 MHz
320x240	6.1 fps	8.6 fps
160x120	7.4 fps	10.2 fps

Walking costs roughly another 45% — loading and meshing chunks lands on the
main thread. A real play session at 256x192 and 1800 MHz measured 5.0 fps.

This is enough to build, explore and potter about. It is not enough for combat.
If that is not what you were hoping for, it is better to know before you start.

Install

1. Extract the archive at the root of your SD card (adds three folders under
   App/).
2. On a PC, download your own APK — 32-bit armeabi-v7a, version
   1.2.20.2.
3. Copy the .apk into App/mcpe/apk/.
4. Launch Minecraft Bedrock 1.2 from the Apps list and follow the installer.

Needs about 1 GB free: ~36 MB port, ~292 MB extracted game, and a 512 MB swap
file the port creates on first run.

Full instructions, controls and troubleshooting are in the README.

Settings menu

Every launch offers presets, with Custom behind them for a specific
resolution/clock mix. The overclock defaults to off and is opt-in.

Overclocking

Optional, and it works: 1800 MHz gives +33%. But the console has no thermal
throttling, already idles near 70 °C, and reached 82 °C in sustained play.
There is no voltage control. Stable on the one console tested; yours may differ.

Known issues

• A line of build info (version, renderer, FPS) sits across the top of the
  screen. It is Minecraft's own overlay and cannot currently be switched off —
  dev_showbuildinfo is stripped from options.txt on startup. Cosmetic.
• At 160x120 the main menu's Settings and Store buttons fall off the screen
  edges. Relaunch at 320x240 when you need them.
• No Xbox Live, Realms or Marketplace. Dismiss the sign-in prompt with R2+B.

Verified

• Clean install on OnionOS v4.3.1-1 (stable) and v4.4.0-beta.
• The archive contains no Minecraft content — the build script fails rather than
  packaging any.
