# Amalgamate
|

|

|
The standard RETRO system is built using the Nga VM[1] and a
|
||
|
copy of the image exported as a C source file[2]. I sometimes
|
||
|
prefer to have these as a single file for easier sharing. This
|
||
|
is a quick little tool to combine them.
|
||
|
|
||
|
Output will be written to stdout.
