'''GXA''' (also known as '''XCar graphics'''; correct name and origin unknown) is a graphics resource format that was used by a few video games. A file contains one or more raster images.

Games known to use GXA:
* ''T-Mek'', by Atari Games, published by Time Warner Interactive and others. DOS version by Bits Corporation, a.k.a. Bits Studios.
* ''XCar: Experimental Racing'', by Bethesda Softworks and Media Technology
* ''The Elder Scrolls Adventures: Redguard'', by Bethesda Softworks

== Format details ==
GXA files use both big-endian and little-endian byte order.

== Identification ==
GXA files start with ASCII "{{magic|BMHD}}", and end with "{{magic|END&nbsp;}}".

They usually (always?) have bytes (hex) {{magic|00 00 00 22}} at offset 4, and ASCII "{{magic|BPAL}}" at offset 42.

Note: It's rare but possible for a Windows [[BMP]] file to accidentally start with "<code>BMHD</code>", so it could be mistaken for GXA. It doesn't help that both formats can use the '''.bmp''' extension.
