Title: crtc info
Post by: Fran123 on 19:37, 15 April 24
Hello,

I am trying to understand the crtc and the information it handles to try to emulate the generation of the image.

I think it would be very helpful for me to understand the meaning of the VCC, VLC, R52, VSC, HDC, HCC, VTAC, HCC, HSC, VMA, VDUR, MODE and ICSR fields

Thank you!

a great document!

now I have to implement the raster, and I'm not sure how to represent when the synchronism is not correct.

hello

See if you can help...
Under what conditions does HDC not increase and take a negative value? How is that negative value calculated?

thank you
