Black screen on 15kHz arcade monitor via VGA #4

Trying to run this core via the VGA port on the analog IO board, connected to my multi-sync arcade monitor (15kHz, 25kHz, 31kHz) I get a completely black screen. The MiSTer menus also do not show up at all. However, it doesn't seem to be locked up as I can still select a new core via the MiSTer F2 menu (albeit blindly). This is with the vga_scaler=0 (disabled).

If I enable the scaler as follows:

vsync_adjust=2 video_mode=6 vga_scaler=1

...when the core launches for a brief second I can see the Qbert attract screen at 31kHz sync, then it goes completely black again.

I manually downloaded the latest Arcade-QBert_20210308.rbf file and tested that, though the one I had installed previously via update_all script had the same date on it. Same results as noted above.
