Hello Artem,

please avoid attaching complete demos (even if they are small).
Demoscene stuff will never go away - unlike many companies/app downloads :) 

The 64k demo works fine for me here.

wine: Unhandled exception 0x80000003 in thread 30 at address 0x404e02 (thread
0030), starting debugger...
--- snip ---

I debugged the app to find the place where the assertion is triggered.
One has to use hardware breakpoints (early softbp get corrupted by unpacker
code) or use breakpoints on win32 API such as GetProcAddress/LoadLibraryA to
set softbp later on unpacked section.

The demo unwraps itself and finally the code can be seen:
