# gtasm
Takes a .**_vasm_** or .**_asm_** or .**_s_** assembly file, (**_vCPU_**), and assembles it into a .**_gt1_** output file.</br>

## Building
- CMake 3.7 or higher is required for building, has been tested on Windows with Visual Studio and gcc/mingw32<br/>
  and also built and tested under Linux.<br/>
- A C++ compiler that supports modern STL.<br/>

## Usage
gtasm \<input filename\> \<start address in hex\></br>

## Address
The address, (**_specified in hex_**), is the start address of the vCPU assembly code.<br/>

## Output
gtasm outputs a standard .**_gt1_** file, containing the start address and segments of the assembled code.<br/>

## Logging
Warnings and errors are output to **_stderr_**, (console under main window in Windows).

## Example
gtasm starfield.vasm 0x0200<br/>
