Save yourself a lot of grief.

For History sake
I am going to respond:
Hmemcpy was a 16 bit "Native" API, used in win 95 and 98 systems, which were 16-32 hybrid.
Its original intent was to implement (H)uge (Mem) copy (cpy), taking advantage of native asm instructions used to quickly mass copy big segments of memory using the DMA features introduced into the 286 processor.
It became popular among crakers of yesteryears, I among them, because it got invoked by most windows API that would capture imput from a buffer in a text window (the serial), and store it into a buffer that was passed to the API as a parameter. . . This was a "Universal" method to track serial and password analysis and validation
Needless to say, for multiple reasons, this trick is quite outdated, hardly ever works these days.
Narvaja proposed a method to implement a Hmemcpy-like functionality within ollydbg, which suppossedly works in newer, XP like systems.
I most confess I have not found it very useful.
It has been translated to English, You may search for it.
