Hi pete.better late than never .
But yeah ,i should do a video of my pal-i psone working perfectly fine with this scaler.
The main problem it seems ,is just with the scaler and it's V settings.For my jp pre tmss mega drive the default settings at either of the 4 resolutions ,all work from the get go,but when i plug in my old style black ps2 ,the image is fine on the console's main bios/settings screen ,but using silent hill 3/gradius V as a test,this shows problems as soon as it starts displaying any content from disc (logos ,text ,loading screen).
Half the screen is missing off the bottom,sometimes the images ,text etc ,will just remain static and switching through the scaler's input sources and back to rgbs is the only way to refresh the screen ,but again,this will remain completely static and shaking.To correct it ,all i had to do was to first adjust the scaler's V size (making the V size smaller)and as soon as i started reducing its size ,the image became normal .Then just mess with the V position.
Now,if i go back to the main ps2 bios/settings screen,it will be completely borked ,but i just leave it like that ,as long as i know the game i run will be correct. Now my psone and ps1 , they run fine(but after correcting the ps2's problems ,this makes the psone completely borked,so i just have to re adjust the scaler's V size to fix the problem of the " no signal"/static image/half missing screen ) ,the scart cable is use for all the PSs ,the scart plug has the 220 uF caps on each RGB line.But when i made a sync splitter/cleaner RGB scart box for duddy roar and his commodore monitor,his md wouldn't work with it,but his AES and snes would.All i did to get his md to sync ,was build him a scart lead without the caps .
I'm positive the 1 scart lead i use for all the PAL-I sony consoles ,is a uk model.It has 2 Vss/gnd wires coming from the console's connector and these are not common to the 4 Vss/gnd pins in the scart plug(each go to 1 group/point of 2 Vss/gnd pins).It has the resistor across scart pins 8 and 16, I'm using rgbs @480p on the scaler,the clamp settings are at default.My lm18 is inside a scart switcher and it's powered by each console's Vcc scart pin(8),i've used a .1uF smoothing/decoupling cap across the lm18's power rails (right on top of the IC)as without it,i had niggles with a commodore 1080sd-1 monitor)) .And the lm18 is only supplying csync to the scaler's S (sync )point.Whether i use just one Vss/gnd pin on the scaler,or all of them ,it doesn't matter ,as all the Vss/gnd points on each of the scaler's input connectors are all common,same as the CSYNC and HSYNC(these two are connected to each other) and VSYNC points.
My scaler's psu is rated at 5Vcc @2.5 amps and never goes beyond or below the rated voltage stated.That diy slg is also powered from the output vga port of the scaler .But the only problem i do have now with that scaler,is a slight ghosting effect when using rgbs mode.Component is dot on though.

Another game of note,regarding testing a scaler's ability to handle shadows (30hz flicker etc)is strider,on the mega drive ,a jp 60hz game.On the very first stage,there are these search lights/beams ,which go left and right ,this scaler just can't handle them .So now i have the scaler bug ,(and now i can finally get rid of my 1084sd-1 and 4/3 trinitron )what other reasonably priced scalers would be able to handle those types of common problems ?
