mhtd6 , the problem lies with that these player manufacturers often "copy" each other.
So, probably "Wilson Co." was the first manufacturer to create the firmware for these players, and other manufacturers started copying, even the name.
But i maybe wrong, who knows.
From the picture you linked, is your player a 1.5" screen?
There is only 1 CTW500 firmware for 1.5" screen in the downloads section here

If this does not work, then you'll need to continue trying all the v9.0.xx series firmwares for your screen size here
