Strange idea, re. Oregon Trail

["Steve \"Usotsuki\" Nickolas" <usotsuki@verizon.net>]

Oregon Trail seems to be a little bizarre, but at heart, it's just DOS 
3.3 and a mix of FPBASIC and ASM.

With that in mind, I thought about hacking it to work with UniDOS, to 
perhaps hack it to fit on a 400K image (for ApplePC and Apple Oasis) or 
a megadisk (for Dapple), and maybe figure out what the hell else might 
be going on with it.

It doesn't like a hacked DOS on the disk.  Perhaps it's trying to read 
something from the boot sectors.

The key here is something embedded in HELLO, starting at address 2208. 
Perhaps one can figure what it's trying to do, and modify it so that it 
will work with a stock DOS (perhaps a disk that has been "dedos'd", 
allowing for room to store the file in the DOS area - it's bulging now), 
and once that... I booted a UniDOS disk, swapped in the Oregon Trail 
disk and typed RUN HELLO and the program worked normally, so it's not 
the OS, it's just the contents of the DOS area, very strange indeed.

But Oregon Trail would benefit from a 400K hack, I think: stuff the 
whole proggy on a 3.5" disk, instead of 2 5.25" disks, or have a SINGLE 
disk image... It's an idea I'd like to pull off, as I am sure it could 
be done.
