Hi guys, a few days ago I posted that I was having problems with some red and blue tones using a MiSTer FPGA (in my case, the QMTech one) on a Sony Trinitron. Keep this in mind if you're thinking of purchasing a vga-scart cable for the Mister from RetroCables, because to get the reds and blues correct on a Trinitron, you'll need to solder a 1K resistor to pin 20 of the scart connector. I'm attaching photos to clarify, so it might be helpful to anyone who has or will have the same problem. I don't know if all cables are made like this, even those made by other online stores, but the one sold by RetroCables is like this.

Hi everyone, I already posted a few days ago because I can't figure out why the colors on my Sony Trinitron when I use the Mister FPGA from QMTech are so faded and dull. I'll post some example photos: where the Out Run arcade core is running and the 240p test on the SNES core. If you look closely, the sky in Out Run should be a very strong and intense blue while it's green, while the background in the 240p test is faded; it should be a much stronger blue. The TV works perfectly, and with other emulation systems like PC/Raspberry, the colors are correct. I also use it with a PS2 and a Dreamcast, and there are no color problems with them either.

In my previous post a few days ago, someone suggested that it depended on the I/O board supplied with the qmtech mister, which can only handle up to 18-bit colors. To solve the problem, you need an I/O board that supports 24-bit. However, the systems you see running in the photos are below 24-bit. The systems that support 24-bit are PS1 and Nintendo 64 and Saturn. So, I'm not convinced that's the problem. Please give me your opinion, because I can't figure it out.
