Whoops. The chroma channel is screwed. I was foolish enough to use a b&w test pattern and a b&w movie for testing. Got to fix that.

Eliminates jerkiness of 24 fps videos by running the v-sync at 48Hz. It works for me but: - there is no guarantee that it will work with your tv set - there is no guarantee that your tv set won't go down in flames Currently only works with PAL. CAUTION! Experimental 24i version. Uses sync timings th...

I can test it on 2 tv's if you like. Sure. I'll upload some test program in a while. I'm sure more people will be interested in those registers, so if you decipher them, could you share the "human readable terms". I have no idea. They do look somehow familiar like fpe = front porch end an...

The good news - the SYNCH/SYNCV registers aren't rocket science so it's no big deal figuring these out - a SD multisystem tv set syncs just fine to 47.9462 Hz (the closest I got to 47.9520) no smoke or funny noises The bad news - I don't have an oscilloscope so I can't check if all the pulses are wh...

If you interlaced it at 48hz (24 frames) maybe some PAL TVs would accept it as "off standard" since it's quite close. Yes I'm hoping for that. Most of the registers should be pretty obvious if you know about video timing. I'd say that some are somehow decipherable. If anyone has any infor...

- "3:2 pulldown" - absolutely horrible results I even wonder how people from NTSC countries bear watching movies at home - 25 fps speedup patch is already made by some guy from psx-scene and sent to EEUG However I'm just curious about finding a way to produce a 24/48Hz signal from GS. And ...

Thanks, but I have already got that info from http://playstation2-linux.com/ however these aren't of much use as I can't decipher those abbreviations to human readable terms like Sync pulse length and so on. What I'm trying to achieve here is to add a 24p/i mode so SMS wouldn't produce jerks every s...

SMODE1 question

Has onyone had any success figuring out these SMODE1, SYNCH1, SYNCH2, SYNCV GS registers? At least some partial information regarding what parts of sync timings do these bits correspond to.
