How to run the game with 4GB patch fix?

[agsst11]

I started the game through Steam the 1st time to see if I would encounter issues that would need fixed or not before downloading additional files. The game CTD as soon as I reached the cutscene for reaching the stadium right at the start. I downloaded the 4GB patch and ran it on FFX.exe in my Steam folder and then was able to run the game directly from the .exe and get past that cutscene (I played until Rikku told me her name with no other issues, not sure if that means the patch is working or if I haven't encountered areas it would have fixed things for yet). I have 2 questions so far.

Have I gotten to a point where if the patch was going to be needed it would have shown up by now indicating I should be good to play the rest of the game now?

Is there a way to use the patch while still playing through Steam because I'd like to be able to get achievements and use the overlay but since I had to run the patch on the .exe it seems like I would need to run the game directly through the .exe, preventing me from utilizing the Steam features.

Once the exe is patched, you can just run the game through Steam.

The patch shouldn't be REQUIRED to run the game anyway - the most common problem it fixes is green screens during cutscenes/videos, but even when that happens, you can still play (the screen will just be green).

You can also use the UnX mod[wiki.special-k.info] if you like, which includes the 4GB patch and also some other QoL features. Also simply run through Steam after installation.

Note that the game (like many older games) sometimes doesn't quite communicate its state with Steam, which can cause you to miss achievements. If achievements are something you specifically care about, make lots of saves - especially before triggering hard/long achievements. That way you can just reload and try again if the game decides not let Steam know what you did.

Sadly it seems to be kinda necessary.. I was having crashing issues with 10 until I started running the game in Windows 8 compatibility.
After that I got the green screen issue on cutscenes but the crashes stopped.. well they seem to have anyway.

The 4GB patch fixed the greenscreen issues and so far i've not had anymore problems.
It's unfortunate the game doesn't work properly but at least there are ways to fix it.
