Oldie HoMM3 unlimited walk & free castle buildings with hotkeys

homm3_cheat.c

/* HoMM3 version unknown - offsets are probably different in the HoMM3 Complete GoG
so don't bother. They're easy to find though with a memory searcher (Tsearch, Artmoney, CheatEngine, etc.)
This was made around 2002 and it's pretty basic but feel free to use it anyway */
