I claim no ownership or creation rights for any of thes effects; I just modded them to make them work in SF2, and then put them together to make it easier for other SF2 Owners.
v1.00 circa 12/23/2009.
I went through all of my installed effects INIs from all my addons and the various effects packs, like Deuce's, LEXX LUTHOR's Strategic Nuclear Effects™, etc and edited them to make them SF2 shader compatible to fix missing effects like MiG-19 afterburners not appearing, etc.
I used the rule of:
Materials that have BlendOp=BLEND_SRC_ALPHA
EffectShaderName=effectLightLevel.fx
(aka Volumetric emitters like smoke, groundmist, dust).
Materials that have BlendOp=BLEND_INV_SRC_ALPHA_ADD_SRC
EffectShaderName=twColor1.fx
(aka fire, explosion, light, flash, flare, streaks)
Found on Combat Ace Knowledge DB.
I slightly modified LEXX LUTHOR's Strategic Afterburner files so that you can have both Large and Small versions in use at the same time e.g. J58_Large calls the Large effect and J58_Small calls the Small effect. You can see this in the Screenshot for this mod; the one on the left is J79_Small and the one on the right is J79_Large.
I also rewrote some of LEXX's Nuclear Weapons Readme to make it a bit more comprehensible on how to make weapons datafiles call those effects in SF2.
