please confirm tag type you're trying to emulate - looks like the reader is trying to initiate a Mifare authentication which wouldn't be appropriate for this type of emulation.

doesn't that 60 need to be accompanied with a blockno ? its only one byte here. A bit of an odd output.

I need to emulate Mifare Classic tag - I did not found anything ready to use yet and explore how nfc-emulate-forum-tag4 works. The nfc-emulate-forum-tag4 emulate Mifare Plus - as a reader I use NFC Tool Android application. I tried 1.7 release (from repository) and 1.8 builded myself - the issue is reproduced. Please let me know what information can help to identify the issue - I will do my best to provide.

Then emulating a NFC/Type 4 isn't gonna work. Rather sounds like it is working as expected.
