Can you point me to what would be the cause that the returned error code is not printed, it's 0xEE (looking at the emulator)

The OPEN syscall returns the negated error on failure (As documented here https://github.com/Zeal8bit/Zeal-8-bit-OS/blob/main/kernel_headers/z88dk-z80asm/zos_sys.asm#L208)

So in your case you should use neg instruction in your label _touch_error. As such when it returns 0xEE, the returned error is ERR_READ_ONLY (0x18).

Seems like you tried to use touch on a file on the romdisk 😉

ok, then it's expected, as I was indeed doing that on romdisk
