Hello,

I'm an happy CRT user and it works for me. At every Recalbox update I have the issue because of the reset of /boot/config.txt on raspberry pi.
i have to care on many options, but one is set by default on Recalbox you have to care, that is:

hdmi_force_hotplug=1

This option will force the HDMI output. To be sure on latest release, I added hdmi_force_hotplug=0 in my included recalbox-user settings to override this option and allow CRT output.

Here is raspberry pi config definition:

hdmi_force_hotplug

Setting hdmi_force_hotplug to 1 pretends that the HDMI hotplug signal is asserted, so it appears that a HDMI display is attached. In other words, HDMI output mode will be used, even if no HDMI monitor is detected.

Hope that helps.
