The latest version on CSPECT folks have the NEXT OS running on is v2.19.4.4, with version 2.08 of NXOS, what version of NXOS are you running on CSPECT.
Do there ZX Spectrum Next games run ok in the same environment ?
I would update to 2.08, there is a disk image available on Discord https://discord.gg/7XjtYXGz under #shared-files that works with CSPECT v2.19.4.4
It seems I am experiencing the reset loop that Mike Daily mentions in the comments of his latest release about CSpect compatibility with 2.08. I noticed your comment about getting it to work and posting an image file. I am trying to use the 2.07I emulator image from here: https://www.specnext.com/distro/22.10/sn-emulator-22.10a.zip. I've tried try with Cspect v2.19.4.4 as well, still no go!
