Here's the debug log. Log taken after scanning mobile written tag: https://logs.zaparoo.org/SKmqCgO5.log and here's log after scanning zaparoo re-written tag: https://logs.zaparoo.org/DMHMIKhM.log (note that I had to perform a reboot after the game launch to go back to main menu and zaparoo script to fetch the log)

I ran into a weird issue with NFC tag writing. **Short answer: **new and unused NTAG213 tags written with the Zaparoo phone app don't work on my Mister device unless I first write them the Mister Zaparoo script.

**Long answer. **I have Superstation One with Zaparoo Core v.2.15.1 script installed (I use the script only, and not front end). I also have the Zaparoo phone app (v.1.11.2) on my iPhone, with up-to-date game database synced from the SSO.

1. I take a brand new unused tag, and use the phone app to write a game launcher to it using the phone app.
2. App says "write succeful" and I proceed to test it with my SSO.
3. SSO is currently in the main menu core. I swipe the tag, and I can hear the "zaparoo sound effect" but nothing happens.
4. I then go to scripts-menu on my SSO and launch the Zaparoo script.
5. I try swiping the tag again, and Zaparoo menu shows that the tag does have the game data written to it.
6. I then use the write functionality in this Zaparoo script to write the game data to this same tag, using the NFC module in my SSO. Write is succesful
7. I exit the Zaparoo script and return to Mister main menu. I swipe the tag again and this time the game launches correctly

Extra notes:

1. I have confirmed that new tags work on the very 1st write when the 1st write is done via the Zaparoo script, instead of phone app
2. I have confirmed with another app on my phone that I am able to succesfully write tags that work on my Mister device, ruling out faulty NFC sensor in my phone
3. It doesn't matter which game I write to a tag as the "first write" with the Zaparoo script, as any game written will make it instantly launchable on my Mister device
4. After a tag has been written at least once with the Zaparoo script on my Mister device, I can write whatever game I want with the phone app to it and it launches correctly (doesn't have to be the exact same game)

With one of these freshly written app tags, can you please tap it on the mister and then upload the log file. Then after you turn it into a working card, tap and then get a second log file. Enable debug mode as well so I can see full nfc reader dumps
