I've made dll wrappers for iforce and sidewinder specific forcefeedback protocols!

I-force 1.0 forcefeedback wrapper
https://github.com/sonik-br/IForceWrapper

Sidewinder forcefeedback wrapper
https://github.com/sonik-br/SideWinderWrapper

Makes possible to play some older games with real FFB or even rumble on modern devices.
Some of the tested i-force windows games are:
NFS : SE
NFS2 : SE
DESCENT II

Some of the tested Sidewinder windows games are:
MDK
Outcast
Die by the Sword

And for i-force DOS games, there's my fork of DOSBOX
