Well if the rules say you are not allowed to use any other console besides the ones the Mods have told you its kinda normal to have the run declined.

It would be impossible to do research on every type of console/emulator so we have a set list of what is accepted. If another method is popular enough then we will look into it and add it to the list if it is deemed acceptable. Right now we are not going to add the Classiq 2 HD, but if there is greater demand for it to be added then we can look into it. To me it does not seem high priority since you are the only one to have submitted a run with it and you have other methods of submitting runs that we will accept.
