Note from porting author: i've had to swap endianess in the original sources
for obvious reasons.

BUILDCPR (c) Kevin Thacker 1999. 
This program will build a cartridge image (.CPR) suitable for WinAPE32, Multi-Machine 
and Arnold CPC+ Emulators. 
Input is a binary file without any headers, and output is the .CPR file. 
Any file between 1 byte and 512k in size can be used. (512k is the maximum 
size of a cartridge for the CPC+).
