Superpak3 is a Mod of falcon4 rather. It fixes a lot of bugs, and currently I have not experienced any crashes after installing it.
It modifies the F-16 in falcon4 to actual Block52 standard. Without the mod, the falcon felt more like a Block 30 machine. They added new weapons such as the JSOW and of course, fixed the AMRAAM bug.
AI actually goes all out to avoid getting shot now, and most goes all out to kill you. With SuperPak3, u get 2 Multi-color MFDs, yes no more green only. Added an LRS to A2A radar mode. (was wondering what happened to that). They reskinned a lot of the planes, so they look better... (esp. the F-4Es) and the added a few more planes, eg. EF2000, TornadoADV, Su-27+ family (including uncles n aunties n grandsons),
And to if you choose to power up you F-16 off the ramp instead of just taking off. Well, read the manual. You actually have to power up all the various sub-systems, calibrate your INS, Altitude warning, n finally starting up your engines. Its the closest you get to the real thing.
