GameMaker to file...?

[Steve Nickolas <usotsuki@buric.co>]

So I was experimenting with GameMaker, and I found that its "compiled" 
disks have a set format.  (Of course, they're single-load.)  I got to 
thinking about how it might be possible to re-compile its disks into 
single files, possibly right in DOS 3.3.

1. The disks have their own bootstraps, but they have a DOS 3.3 
filesystem.

2. They seem to always have the following directory structure:

*T SEC FILENAME   ADRS LNGT ENDA
 B 026 PRED1 /WDA 0800 1800 1FFF
 B 042 RUNT2 /WDA 6000 2800 87FF
 B 042 PROG  /WDA 8800 2800 AFFF
 B 034 SCENE /WDA 4000 2000 5FFF
 B 010 RUNT3 /WDA 4000 0800 47FF

At runtime, SCENE /WDA is loaded to both 2000 and 4000, and RUNT3 is 
actually loaded on the language card (punch C089 a couple times and move 
it into place).  The other files are loaded at their designated addresses, 
and execution begins at 6000.

I am thinking it may be possible to automate a conversion to single-load - 
and all the better if it can be done using the native operating system?

I'll try to code up a proof of concept later.
