Error 141: cannot compile overlays to memory

[Amylase]

Hi, I'm trying to compile a helicopter game dated some 15 years back.
The game, its source code and the compiler are all freewares now.
The game is called Chopper Commando.
It was written in Turbo Pascal and according to the author, he was
able to compile it using Turbo Pascal 5

I got hold of the the source code and tried compiling it myself but
I keep getting this message: "Error 141: cannot compile overlays to
memory".

I used Turbo Pascal 5.5, first time in Windows 7's dos mode (cmd.exe),
later also tried in Dosbox.
I also tried turning on and also turning off Compile -> Option ->
Overlay.
I keep getting the same message: "Error 141: cannot compile overlays
to memory".

I also tried using Turbo Pascal 7 and Free Pascal. They gave me
different errors such as unable to find TPU file or incompatability
issues.

I might try running Turbo Pascal 5.0 in a real 100% DOS machine. But I
doubt that'll help. Could someone kindly help me over come this error
please?

Thanks a lot.

Here's a clip on youtube showing how cool this game is

Somewhere in the compile menus you can probably change compile destination
from "memory" to "disk"

FPC has no graph3 it seems (which was TP3 backwards compatibility).

Does sb know a substitute?

I was able to build the game by just running "tpc chopper2.pas /b". I've
used TP 5.5.
