Well, if that is what you say is the case, then I believe you. I'm not an expert at all in how faithful graphics enhancement works, but I'm certainly a fan.
After taking a look of some of the screenshots of the Steam version, it seems like SE already did a pretty good job of upscaling the graphics and FMVs. About the only complaint I have is the battle backgrounds are a bit too blurry, but I came across this mod...
http://forums.qhimm.com/index.php?topic=14469.0Apparently it does a better job upscaling the battle backgrounds then SE did. I'll probably just use that, combined with the Linear Filtering option to make a respectable looking enhancement to the graphics (New Threat already replaced the character models in the game).
About the only other tweaks I would like to see to your mod are the following...
-If possible, try to solve the few issues the 60 FPS Battles mod has.
-I understand you have no interest in other mods. However, I REALLY have to stress how much it sucks that New Threat is not compatible with your work. I do not know if you have taken a look at that mod, but I think anyone will agree that is does a fantastic job at updating the gameplay. It almost feels like I'm playing an official remake by SE, and I'd like to think that part of an official remake would include a brand new, accurate translation (See the FF IV-VI Advance ports). Your re-translation and 60 FPS mods would go together with New Threat like bread and butter.
If it would take a commission to get you to consider making a compatibility patch, then I would be more than happy to pay. I am serious about my love and passion for this game. I would only ask that you wait until the final version of New Threat comes out.
-A mod that remasters the SFX of the original. One was already started over here...
http://forums.qhimm.com/index.php?topic=10237.0But it was sadly never finished. You seem to be a big fan of faithful enhacement of original assets, such as myself. You also clearly have a lot of dedication to finishing daunting tasks like re-translating an entire PS1 game, so I feel this project would be a perfect fit for you. Again, if a commission is what it would take, I am willing to discuss terms.
