+EMU51 
+-----
+
+Emu51 is a 80c51 emulator
+
+![Emu51 v0.0.1 screenshort](docs/emu51.gif)
+
+### Informations
+
+(from the original Readme file)
+
+Emulator accepts `*.bin`, `*.hex` files. 
+You can also compile source file by using external compiler, emu51 is compatible with  free 8051 compiler by 
+MetaLink Corporation (http://www.metaice.com/ASM51/Files/ASM51.zip).
+Just put asm51.exe into this directory and use Shift+F9 key combination to compile and load source file 
+(only windows :-( ).
+I'm still searching multiplatform 8051 assembler compiler for emu51, because I want to add full compilation 
+support for all supported platforms.
+
+The original version from Mariusz Kasolik and can be found here: https://emu51.sourceforge.net/

--------------------------------------------------------------------------------

-Source file (platform independed)
----------------------------------
-
-Emulator accepts *.bin, *.hex files.
-You can also compile source file by using external compiler, emu51 is compatible with
-free 8051 compiler by MetaLink Corporation (http://www.metaice.com/ASM51/Files/ASM51.zip).
-Just put asm51.exe into this directory and use Shift+F9 key combination to compile and load source file (only windows :-( ).
-I'm still searching multiplatform 8051 assembler compiler for emu51, because i want to add full compilation support for all supported platforms.
-
-
-You can find history in the file of the same name.
-
- - Compilation has been tested with VisualStudio 6 using latest (4.1.9) allegro library.
- - Compilation tested too with DJGPP with GCC 3.2.1 and allegro 4.1.9
