Here is Free Heroes 2, an engine that let you play the classic Might & Magic Heroes 2
This version is almost vanilla, with just some changes to have good speed on the Pandora.
You need the Datas from a full version to play this one. You need to put all *.AGG files from DATA folder inside apddata/fheroes2/data and all *.MP2 files from MAPS inside appdata/fheroes2/maps.
Alternatively, if you have the GoG version, just put the Windows setup exe inside appdata/fheroes2 and the data should be automatically extracted.
* Fixed autoextraction script
* Initial build
* Some Pandora optimisation
* Autoextraction of data from the Windows GoG version
