Not Working on "Space Beast Terror Fright" Game

Hi Guys, I'm in love with reshade and with this gem:
store.steampowered.com/app/357330/Space_Beast_Terror_Fright/

I really think it nails the "ALIENS" movie atmosphere
Graphically is a bit rough, and I'd looooove to be able to inject Reshade. Unfortunately, i cannot make it work. It seems to have only windowed mode or borderlessFS.
It uses dx9.0 API and shader model 2.0. Please can someone help?
Thank you!!

If the game does not have any kind of external software protection, it should allow for reshade to be injected, regardless of missing fullscreen mode.
If you're sure you picked the correct game executable during installation, try choosing another API.

thanx for your reply
Yeah I tried all the APIs one at a time, i even tried the 2 dlls provided by ThaxLite in this post
reshade.me/forum/general-discussion/4083...dification?start=520
which apparently solved the problem on source games...

As of now I'm quite familiar with reshade installation and set up, I reshaded and played 20/30 games, but this one makes me bang my head on the wall.
I think the issue is the shader model 2.0
