# MCPI-Reborn Runtime
**Fact:** Minecraft: Pi Edition is a 32-bit ARM program.

**Another fact:** Most modern computers do not use 32-bit ARM and therefore cannot run MCPI natively.

**Solution:** This project allows MCPI to run on modern computers.

## How
This project works differently depending on the host system's architecture.

### 64-Bit x86 Host
On this platform, a patched version of QEMU is used.

QEMU emulates ARM code so MCPI can run on x86 hardware. And the patch adds a system-call which allows MCPI to run graphics code on the host. This prevents the need for emulated GPU drivers.

### 64-Bit ARM Host
QEMU is not necessary on this platform because it can already run 32-bit ARM code natively.

Instead, the runtime is implemented as two processes: a parent and a child. The child becomes MCPI and can send graphics commands to the parent. And because the parent is 64-bit, 32-bit drivers are not needed.

### 32-Bit ARM Host
This project is unnecessary on this platform.

### Other Architectures
Any unlisted platforms are unsupported.
