Since it seems MSClassic is completely unattached from GMS for the time being (data wise), I will make a new thread for MSClassic client archiving.
As of right now the first wave of keys were given out, and people having those keys are able to download the files.

I have no interest in REing the client, only preservation.

Global runs on a base from Modern KMS client while the other so far are a Unity source port (suspected through AI).

It's possible quietly in the background more patches get made. If you notice your game has to patch, let it patch and after it patched make a local copy of your Mushroom game directory and try see if the last modified dates changed for particully MapleStory.exe and your Data folder. It's likely those get changed very frequently. Especially the data folder for balancing changes.

Right now the full data is very small (less than 1gb), so full backups and uploading them is very appreciated if you noticed a patch happened. You can delete it after if you wish, since I'll be mirroring it and re-uploading it.

Thanks for helping preserving MSClassic!

EDIT: It appears GMS does not update this right now in CW, so its not a good indicator.

A video that has started appear seems to suggest the version tag as traditionally will appear too in the top right corner of the login screen. Although, its hard to see.

This should help as well knowing when your game has updated. Do note though that the version tag only updates when the .exe has updated. It's possible they will do only data updates as well.

An official chinese version of Classic World is announced and confirmed.

I am even less involved with the Chinese region, but hopefully someone out there can do the same thing as here. It seems also it will be very different, and they start with Pirates AND HPQ.

Please preserve as much versions of the client as possible.

Added patch April 13, 2026. This seems to be the closed beta "day 1" patch, with small data changes and a maplestory .exe change with a build date of 2026-04-13 16:57:13 UTC.

This patch likely happened on the day CBT happened, but only now was informed about it. Updated OP.

This is for preservation/client-server development. To play actual Classic, you need have actual access and use their launcher to play.

--------------

Added patch April 20, 2026 (Released April 21). This is the patch that made the new map, Forgotten Hollows public. Only the .exe was changed apparently. It's possible this will be the last patch before Closed Beta ends. Also, the login will keep refer the .exe as "Ver 0.1.0", which is a bit annoying.

Bah, annoying RaGEZONE rollback. I update OP soon again with the additional info I did put there ... less than a week ago.

Chinese MapleStory Classic will have their first closed test On may 20th!

Only 2,000 sign ups are accepted.

This is dangerously little for how many people there are in China, but hopefully one person out there could help preserve the clients. We are actually really curious if they use the OG client or the modern client. I personally think it will be modern like GMS, since its just unrealistic to use server binaries and files from 2008 or whatever, but we'll see.

Closed Beta of Chinese service has launched. I have no access to it

OP updated, thanks a lot chuichui! It seems CMS ported/re-written the game to Unity, which I can only assume is for long term plans. Example, mobile support and or browser support is much easier done through the Unity engine compared to the modern KMS client GMS CW uses.

We'll have to see what they do in the future.
