Hi everyone,
First time posting here!

I’ve successfully jailbroken my Kindle Paperwhite 7th Gen, running firmware 5.16.2.1.1, and I’ve been trying to get Frotz (Infocom game interpreter) working using the well-known 2017 release (frotz-2.43d-kindle_k5_kterm_kual-1.1.2.zip).
Here’s what I’ve done so far:
Installed KUAL, Frotz extension, and the dialog-based launcher UI
(downloaded from
https://www.ifarchive.org/indexes/if...preters/frotz/)
Placed frotz, dialog, and .dialogrc in /mnt/us/bin/
Verified that the .z5 game file is in /mnt/us/if/ (tested multiple known-good files like hitchhik.z5)
Set correct file permissions in kterm using chmod +x to which I got permission denied errors.
Launcher UI appears when I open from KUAL. I can select the file, but after tapping OK, it immediately crashes back to the home screen (no error)
I strongly suspect this is a firmware compatibility issue. I’m guessing the newer firmware no longer allows execution from /mnt/us/bin/ (FAT32), or there are additional runtime restrictions that break this build of Frotz.

for all your help!!!
