[Feature request] Optional timings for CRT Tvs #35

Open asturur opened 1 year ago

asturur commented 1 year ago

Would it be possible to have an option in order to output timings that are NTSC/PAL tv compatible?

I understand the intent and purpose of this would just to avoid people having a CRT monitor and a CRT TV for different cores, but i would like to undertand if this would be a possible option or an impossible option because of technical requirements ( factoring out the need of an extra configuration bit )

I would say that there is not much that can be done about this, the limitations are set by the requirements of the CGA/Tandy module based on the Graphics Gremlin project.

i wish i understood better the requirements and the difference. My tv actually display something but half shifted on the right and clearly in distress.

Thanks anyway for the answer!

Just as information, when booting the machine, CRT tv display is fine. The 640x200 text screen is perfectly fine. The TV sync on that and is great.

When starting some application ( alley cat or arcade volleyball ) , depending on the application, while all being reported as 640x200, some part of the screen shifts and distorts.
