Linearity corrected by paulb_n in the 240p Suite and comparison

Unread post by Artemio »

Just to let Paul know that he was right a few months ago about PC Engine linearity being wrong on the 240p Test Suite, and how his pattern compares between a Duo R and the MiSTer on a PVM

The original thread: https://shmups.system11.org/viewtopic.p ... 0#p1411390

Direct video (pardon the quality, I wanted to show it ASAP): https://www.youtube.com/watch?v=VXZ4XlYO2h4

I'll do the same with composite in order to verify if the horizontal offset is due to the RGB mod (I've seen that happen in other models). I'll check with the scope later on otherwise.

Thanks for the excellent work!

Thank you all for the hard work!!

Does this mean aspect ratio is correct at all resolutions? (sorry for the dumb question)

Yes the aspect ratio is the same as you would see on a CRT. This does mean the 320 width resolution is a bit narrow because that's how it is on a CRT.

Awesome! Just need the horizontal offset corrected (possibly) now. I noticed the 240p suite has some grid tests shifted to the right. Maybe the 240p suite needs to be updated rather than the core? I am using one of the 240p test builds.
