Square Enix has revealed that the Steam version of Chrono Trigger will receive updates over the next several months to address the various issues people have raised concerning the port's quality.
Most immediately, the first patch will launch in 'the first half of April', which will include an option to toggle between the port's current graphical style and the original graphics. Additionally, the game's "Limited Edition", which includes a bonus music medley and wallpapers, will be available until the end of the month. After that, it seems the game will simply be available without the bonuses.
We've quoted the Steam forum post below, which can be found here.
Thanks for all of your feedback, patience and support so far.
We have been working on addressing the issues that you’ve raised, and will be releasing a number of patches over the coming months as we continue to support CHRONO TRIGGER on Steam.
We’re aiming to release the first of these patches in the first half of April, and the biggest change is that it will include an option to switch between the current high-resolution graphics, and the original graphical style of CHRONO TRIGGER.
We’ll post a full list of changes here when the first patch is released. For now, be assured that we’re working very hard on adjusting, updating and supporting CHRONO TRIGGER on Steam.
As CHRONO TRIGGER is going to receive patches over the coming months, we are going to extend the availability of the Limited Edition until: 5PM, April 30th BST / 9AM, April 30th PDT
Thanks again from all of us on the CHRONO TRIGGER team.
