Most 25th Anniversary fixes and tweaks still not present in Opposing Force and Blue Shift

[ChiroTheSkunk]

It seems that grenades in both Opposing Force and Blue Shift still have the old physics from the Pre-Anniversary build, Satchels still have the Pre-Anniversary controls in both Opposing Force and Blue Shift.

Also, can we have the Retail Gearbox startup video restored in Opposing Force and Blue Shift? aswell as the Retail menu fonts for Opposing Force as seen in this video?: https://youtu.be/urxhOn_iWnM?t=23
This would bring back memories, thanks!
