Strigon Squadron livery for Su-35 Super Flanker and Su-37 Terminator.
Strigon Squadron's dark red camouflage for Su-35 and Su-37. Ported from the previous release for Ace Combat Zero, which you can get here.
Inject the .gfp files with the GFP Injector you can get from the tools bundle into your ISO to use these skins.
Update (08/06/2023):
Added alpha-masked .png files of the liveries for use with PCSX2's new Texture Dump and Replacement feature.
Can acz texture mod can't apply for ac5?
My apologies for the late response. The files used for livery injections on both games are different, so you can't directly apply a texture mod from Zero into 5.
