Black Screen in C64 Core

[rcade]

I have both an LCD attached to HDMI, and an analog board with RGB connected to a Sony PVM.

I will say that very often the core just shows a black screen for me on the HDMI out, but it always works on the RGB monitor.

I wonder what this core does differently. I had a look at the Verilog but its beyond my current understanding

Did a few more test switching hardware and video modes in the core. Still the same. Tried booting a few .crt's and those sometimes result in the C64 basic screen with random-ish characters around the screen (like in the screenshot). Sometimes something that looks something like a normal C64 loading screen with flashing colors. Sometimes a few SID bleeps and bloops. It's all very random. Just to repeat what i said earlier in the thread: every other core i've tested works just fine.

HOLD IT! Todays (20210509) release suddenly started working. Other people that have had problems with black screen and other weirdness give it a try!

Todays release has fixed my issue I finally can load the C64 and enjoy the Sid and games

Thank you Sorg for all the work you have done.
