I just got a Master System Converter II for my MegaDrive today. Hurray! now i can play my Master System games which have been collecting dust for years.
Unfortunately i can't get a picture on my XRGB-3 in B1 mode when using this thing. Its the same on both the D2 and RGBs input.
If i switch to B0 mode and disables V-sync i do get a picture. But i really was looking forward to playing with scanlines :p so do any of you have an idea why i don't get a picture in B1 mode? I've tried the most obvious AFC settings and V-sync on/off but it didn't make a difference :/ Could it be because of the LM1881 chip that i installed in the MegaDrives RGBs cable?
Atm my XRGB-3 is in B0 mode in 1280x1024 and DOT_by_DOT turned on for correct aspect ratio/scaling. My tv is 1080p native and shows 1280x1024 in 1:1 by adding a little underscan in the top and bottom of the screen. Very clever IMO.
LPF had to be turned OFF because it added a little flicker in the image and with that off the picture is even sharper. This is the most PERFECT picture anyone will ever get when using original hardware on a HDTV set!!
Only downside is that i can't have V-sync on, so slight stuttering appears every now and then. This really isn't that big a deal because it seems almost every Master System game i have suffers from slowdowns anyway... And of course no matter how emulator-perfect-like this looks i still would have preferred scanlines in B1
I should also mention that my MegaDrive II has the best picture/sound output of any MegaDrive i have had so far. I have heard rumors that the MegaDrive 1 should have better sound, but on the two MD1-consoles i've had so far its never been nearly as good as this, add jailbars in the picture and there really is no comparison. MultiMega was even worse...
I also played around with the XRGB-3's 480i capabilities which in my opinion always has been a bit shitty. I decided to test it again, this time using a Dreamcast with a RGBs cable, Rayman 2 and SEGA Smashpack vol 1. Normally i use an original SEGA VGA box on my Dreamcast and the picture is extremely good so i knew already that what the XRGB-3 would output would be quite a lot worse.
After testing a bit i found that in 1280x1024 B0 (the highest resolution my tv will accept from the XRGB-3) mode the picture was actually pretty good. There is some noticable interlacing when moving around in Rayman 2, but the picture is soo much sharper than when connected to my tvs RGBs input. Nowhere near VGA sharp but still pretty damn good, and i would choose interlacing any day over the blurry composite-like picture my tv gives me. Biggest problem is that the XRGB-3 HAS to have the DOT_by_DOT option enabled otherwise the picture is stretched unevenly and will look fucked up in places, this also means that the picture will be smaller than what were used to, so even more underscan on my tv :S Still i think the picture sharpness is a little better than the alternative.
I also checked with my copy of SEGA Smashpack, which holds probably the worst emulated versions of some of the best MegaDrive games ever! I could go on, and on about how shitty these emulations are but thats not really the point is it? Besides Virtua Cop 2 is on the disc so i guess that kinda makes up for some of it.
But this disc is still kind of kewl as the emulated MD games will show in VGA which makes them look perfect, and 480i which is good for comparing the VGA signal that i'm used to with the XRGB-3's 480i capabilities.
Its hard to notice when playing 3D games but when playing Sonic 1 in 480i throuh my tv set its very easy to spot all the interpolation when moving around. The picture is so bad its almost unbelievable

In 480i through my XRGB-3 the picture is a lot sharper, there is no interpolation when moving around but there is some deinterlacing and underscan but still its a lot better overall that what my tv does.
Best possible Sonic 1-picture on my TV:
#1: Dreamcast in VGA - Picture is PERFECT but the emulation is so bad that i can't recommend it to anyone.
#2: MegaDrive 2/Sega Saturn (Sonic JAM) trough XRGB in B1 mode with or without scanlines*
#3: Dreamcast 480i through XRGB-3
#4: Dreamcast 480i connected to tv's RGB input - Its rubbish.
*B0 mode only seems to give a "PERFECT" image when using the Master System Converter II, without it the MegaDrive looks very very good but B1 mode looks the same, obviously i'd choose B1 mode without the 20ms delay.
The reason why i'm interested in 480i from a Dreamcast when i usually only use VGA is because i will soon be getting some of the retarded releases that won't work in VGA mode. 4-Wheel Thunder for example.
Anything you guys would like to add? Have i overseen anything that could make my 480i experiences on the XRGB-3 even better?
Also Fudoh, how does the 480i capabilities on the XRGB-3 compare to the Optoma HD3000 (still haven't bought one yet...), i'm interested in that mainly because of 480i (PS2, GC, XBOX and DC).
I should also mention that my tv does 480i from a PS2 with component cables WAY better than the XRGB-3. Picture is very sharp but still gets interpolated when moving. Strange that there is such a huge difference in RGBs and Component :/
I hope i got all that "Interpolation" and "Interlacing" right. Interpolation is when the picture gets softened and rounded when moving around and Interlacing is when every other horizontal line seems out of place when moving left to right or vice versa, right?
