Gameplay

Good morning from Vienna,

As an old great Fan of the sensible soccer era at the very beginning I am curious about these questions:

is it possible to use gameplay of swos 1995/96 ( I believe it was dos version 1.0) instead of 96/97? 
Or is there any Option other than swos 2020 for using the first pc version as base for modding?

Thank you, Kind regards
Christoph
