Is this it?

I have that downloaded.

I have V1 of the other mod, but I'm hesitant to upload it because it may have been broken with a patch? If you request it and I don't respond in a while feel free to friend request me to get my attention and message me. I'll try to remember to check back.

Unfortunately, search pollution abounds for the original bilinear filter patch. The topic seems to have been deleted. I don't remember if an updated version was ever released. Was that the mod that was hosted for free in a Patreon post? I may be thinking of something else.

I DO have the archive though, at least of 1.0. I'm hesitant to share something that might not work though.

To be clear, this is NOT for the Pixel Remaster.

A real shame there's no middle ground. I think the higher resolution enemies in FFV especially are beautiful in the abandoned version. (Literally abandoned, they never even patched cloud saves to work. They only save the config.)

Remove bilinear file now exists as one of the options in atma weapon multi mod installer in nexusmods.
A derivative of it which excludes UI and fonts is part of the SaneUI mod also found on nexus mods
