MAKE SURE YOU RUN CONFIG.EXE AS ADMINISTRATOR.
This will ensure whatever changes you make are saved.

IF YOU CRASH AND LOSE YOUR PROGRESS
Check page 0 of the saves- you will find autosave points that the game has made during gameplay. See if you have a recent save in here!


*** Black Boxes in Shops
It looks something like this....
http://cloud-4.steampowered.com/ugc/564392637670707743/4203B69FF258B77887DD70E5371E870F3048864A/

This is showing up in places that aren't the shops now. I'm bringing it back into open issues, since I'm seeing comments on it again.

*** Game not starting, save/config issues
From this post: http://gtm.you1.cn/app/251150/discussions/0/35220315610393072/

To make this simple and concise, no I did not find these answers myself (others on here have posted them, I'm simply making a thread so anyone like myself with the issue has a fast thread to reference to).

1) Open steam (as you regularly would), and go to The Legend of Heroes: Trails in the Sky and click "Play"
2) Two options appear - "Play The Legend of Heroes: Trails in the Sky" or "Run Configuration" ... choose the second. "Run configuration"
3) At the bottom will be 4 options -- Click on "Save Folder" ... when this opens, simply DELETE the folder.
4) After deleting the folder, the configuration has options for "Display", "Sound", and "Input" (the default tab shown is Display so you will naturally be on it) ... Simply change your resolution and start the game. From what I can tell, this fix seems to be working every-time; and hopefully it has now worked for you. Good luck!

*** Crashes when Changing Zones
Hearing about this now. Seeing it show up with some responses in this thread.

*** Flickering Title Screen
The title screen starts flickering and there's an inablity to use any of the menu commands. If you try to alt tab, it causes the title screen image to become scrambled.

*** Random crashes while playing at high resolution.
Per Tom on Neogaf, these video crashes are mostly happening at 1080p+. The workaround for this is to lower the resolution for the game for the time being.

This is currently being investigated so that they can find out the cause and patch it out.

Another workaround that I'm seeing is that if you disable the high resolution fonts from the config utility, you should be able to load the game, as well, even at higher resolutions.

Cursor Jumping in Game

I think this is related to auto cursor, when you attack first time the cursor auto jumps to target then it crashes the game.. but if you use attack that doesn't auto target enemy it bypasses it. and lets you attack normally for the rest of the fight.

I'm taking note of this so we can research it.


*** GENERAL RANDOM CRASHES
I'm finding reports of random crashes in multiple places since the latest patch. This includes random exits/entrances, talking to NPCs, going to some shops, and entering some menus.

If you are having these crashes, please state so in the thread and provide your system specs so that they troubleshooting can be done on them. Thanks!

From what I'm seeing in comments, this appears to be caused by the high resolution fonts as well. The primary workaround for it is to turn them off.

*** Missing Textures in Rolent
I'm seeing this pop up now. Let me do some more research on this issue.

I've just read that this issue happened in the original Japanese release, too. This may be a settings issue.

RESOLUTION:
From Neogaf:

For anyone else who is having this issue, turning off Hardware Vertex Shading seems to have fixed this for me.

*** Black Screen after the Boy Says, "My Name Is..."
This is caused by a codec error and is an issue even with the original Japanese version- primarily caused by some of the more recent and popular codec packs (namely CCCP).

First possible resolution is to disable ffdshow for Steam in both video and audio. If this does not work, check the type of codec pack, as the KLite Codec Pack almost always seems to resolve issues involving this game.

*** Mouse Buttons Reversed
Default settings show: RIGHT-CLICK: OK, LEFT-CLICK: ERROR.

Default doesn't always set properly. You can set this in the config tool.

*** Stalling at 'Preparing to Start Trails'
Still trying to find out more information on this. I'll keep you posted based on what I hear on it. Tom thinks that this may be related to the video codecs. Try disabling the logo video from the config and see if the game loads and let me know in this thread.

This is confirmed as a Steam issue. Clear your Steam cache and/or restart the Steam client to resolve this issue.

*** Controller Bug
Dual Shock and 360 controllers having issues, mostly related to the dpad. Still researching.

You can work around this with xpadder, for now.

Quote from Tom on Neogaf about the controller issue:

Also also, like a lot of games that support USB gamepads but not specifically Xinput, Trails uses either the analog stick OR the d-pad -- not both. Some gamepads have a toggle button that let you enable or disable the analog stick, though (most Logitech PC gamepads, for example), so if you've got one of those, you can always press the toggle button when you need to switch between the two input methods. It's far from ideal, but it is a solution.

I'll keep you posted on more as I learn it.

Additional comment on the controller bug:

My game crashing on battle if I use normal attack first ( cursor jump bug) Is fixed if I use, and only use the 1.2k x 800 resolution, all other resolutions and settings have the crash on battle.

*** S-Break with Controller Issues
As described in the thread:

The tutorial will instruct you to hold left/right and press any of the face buttons to activate it, but it only occasionally works if you rapidly wail away on them. Some have reported success with using Xpadder/Joy2Key to map the 1-4 buttons to the right analog stick.

BOTH CONTROLLER ISSUES SHOULD BE RESOLVED IN A RECENT PATCH

*** Sapphirl Tower Treasure Cheast Crash
There is a treasure chest in the Sapphirl Tower that when you go back to look at the empty chest message, it will cause the game to crash. This has been confirmed as having been fixed in a recent patch.

*** Color Issues during the Opening Movie
Are you able to run the movie in the game's files outside of the game? Does it have the same issue then? This may be a codec related issue. Additional note is that these movies do work fine outside of the game.

I'm also hearing that Windowed mode is a workaround for this, too.

Jeovane has also reported a following fix for the color video issues, if you're running an NVidia card:
If you have a Nvidia card, download Nvidia Inspector, open the config option, create a new perfil and set the parameters as in the image below http://abload.de/img/capture85k6g.png

This has been fixed in the latest patch!

*** Game Closing With No Error in Windowed Mode
I've seen a few instances of this. Adding to the list for reference.

Fixed in a recent patch!


* Thank you so much for being patient with me! I don't have access to the game and steam at the moment, so I'm having to work off of reports I'm seeing from people on multiple fronts.[/i]

* Quick shoutout to whitknight28 and livinghitokiri for the awesome help in this thread! The two of you have helped a lot with some of the sanity around here.

* Don't forget to give Sara a big shoutout for all the work she's put into trying to fix the crashes today, too!
