Just scroll down to "FPS MOD FIX"

I'm leaving this guide up with the old information as well (below) just in case.

Have fun!

According to the Discord, this patch is old and no longer being worked on. There are apparently a lot more improvements with the new method. The old method still works, is a lot simpler, and makes a lot of the terrible FPS bearable, but it's apparently not as good and definitely not as well-supported as the new method.


Navigate to the following directory and and make a copy of the save.dat file nested a couple levels down. Yes, that extra space is part of the path:

1. Go to https://www.nexusmods.com/chronocrosstheradicaldreamersedition/mods/11?tab=files
   
   
2. Download the file "isa FPS Hack - The Patcher" and extract the executable
   
   
3. Run the file "isa FPS Hack.exe"
   
   
4. Check "Create a backup copy of the file"
   
   
5. Click [Select file] and find CHRONOCROSS.exe. You can find it by right-clicking the game in Steam, clicking LOCAL FILES, then clicking [Browse...]
   
   
6. Click [Open] then click [Patch!]
   
   
7. DONE!

You can ignore the "Manual Patching" section if the above steps worked.

NOTE: Previously, NexusMods blocked the automatic patcher, so consider these instructions outdated unless it happens again.

1. Before doing anything, find your Chrono Cross: Radical Dreamers directory and make a backup of CHRONOCROSS.exe. You can find it By right-clicking the game in Steam, clicking LOCAL FILES, then clicking [Browse...]
   
   
2. Download the utility named Lunar IPS and extract it: https://www.romhacking.net/utilities/240/
   (Feel free to malware scan it[www.virustotal.com] if you don't trust it)
   
   
3. Download this mod named "isa FPS Hack - The Patch" and extract the files: https://www.nexusmods.com/chronocrosstheradicaldreamersedition/mods/11?tab=files
   
   
4. Run Lunar IPS.exe from the x64 directory and uncheck "Register File Type"
   
   
5. Click [Apply IPS Patch]
   
   
6. Find the IPS patch that you downloaded from Nexus Mods "isa FPS Hack - The Patch" and select that .ips file
   
   
7. Find the Chrono Cross directory you made a backup in earlier. On the bottom-right, make sure All Files (*.*) is selected or you won't see it

You should be good to go now. Run your game as normal via Steam.
Enjoy!

I only wish to spread the word because it helped me enjoy the game at a proper smooth framerate

Note: In the event Square-Enix releases a patch, this may not work anymore and/or you may have to try to apply the patch again. Please join the Moogles & Mods discord[discord.gg] to keep up-to-date.
