LOL, that's exactly the same words that came in my mind when I saw the 1st post  --- DOS gives me freedom to unlimited HW access. |

You represented an 64-bit value as 4 * 16-bit values MPI in real mode dos? |

WRONG. Hadn't I written about DOS ???
As nobody is able to find the solution, here the hot steps to reproduce:
0. Get 32-bit Pentium CPU, get 32-bit Windaube XP
1. Get QAK-64 (21 MiB only), run it, hey it works 
2. Compile "hello.bas" and "3dballs.bas", run them, hey they run too 
3. Check the bloat: both are cca 800 KiB, "3dballs.exe" only marginally bigger than "hello.exe"
4. Move them out of the QAK-64 directory, hey they don't run anymore, identify 8 missing DLL's, copy them, fixed, works again
5. Backup the hot stuff ( here ), DBAN away XP, get DOS, install abandonware "HX DOS Extender", restore hot stuff, patch "libstdc++-6.dll" to a valid DOS filename
6. It works (see shot from "3dballs.exe") ... you can run executables brewn by QAK-64 in DOS 
PS: "hello.exe" needs same 8 DLL's as "3dballs.exe", so the Hello World size of QAK-64 is incredible 8 MiB impossible to beat 
PPSS: I have also better (more useful, less silly, more 8086-compatible) 64-bit technologies in the pipeline
