DVDO iScan VP50 or VP30 w/ABT-102 ?

[rock145]

I am undecided whether to get a vp50 or vp30 with ABT-102 card. Can someone tell me which would look better with ossc. I know vp50 pro is the best but its very hard to find in good shape. When it comes to lag I read they are the same. What I want to know is which will improve the image of 240p games the best. Which has less ringing? I found one at $300 should I get it or wait until I find a vp50 pro?.

How is the DVDO Edge green with ossc?. I heard there is a bug that increase lag on some consoles. What if I connect ossc+DVDO Edge green with a pc with groovymame to send 240p games at native refresh rates; will this lag increase bug be present or it just for some consoles? Please reply. If the input lag bug is not present with groovymame+ossc+dvdo edge green, then I am open to get one.

Got myself a vp50 pro. How do I update the firmware, it came with 1.05. What was the last firmware? Do I need a cable or a cd to update it please help.

Does GroovyMAME try to emulate native refresh rates of the arcade games? If so the Edge Green will have the input lag bug on some games.

To update the VP50 Pro you need a regular oldschool serial cable. a USB to legacy serial adapter should work. See here for instructions and resources – https://shmups.system11.org/viewtopic.php?f=6&t=58498

Thanks for the reply. Yes groovymame emulate native refresh rates of arcade games so dvdo edge will probably have that problem like you said. I look at the link you provided according to it the latest firmware is the one I have 1.05. I thought the vp50 used the same firmware as vp50 pro but according to this vp50 is 1.09 and vp50 pro is 1.05?

What is the most recent version of my firmware?
A:

iScan HD 5.6-1.42
iScan HD+ 6.7-2.91
iScan vp20 1.03
iScan vp30 1.14
iScan vp50 1.09
iScan vp50pro 1.05
Edge 1.63
Duo 2.41
Edge Green 1.01
But with this firmware 1.05 I can’t get line 5x work only line 3x in ossc. I use these setting ossc H.SR 2057, H.BP 255 (BuckoA51, VP50Pro) and I still cannot get it working. Ossc by itself can do line5x with my tv but when I connect it with vp50 pro it does not work. That is the reason I thought I need a firmware update for vp50 pro. BuckoA51 can you tell me the firmware you have in vp50 pro that is working with line5x.

[BuckoA51]

I don’t use line 5x, typically I only use line 3x on my VP50 Pro.

[rock145]

Do you have a reason for it. You prefer it over line5x?.

[BuckoA51]

Line 5x crops the image on 1080p displays/devices.

[rock145]

Got line5x working on vp50 pro. It turn out that cadence is automatically turn on and that causes lin5x to display some scramble graphics on the tv. When I disable it now it displays it correctly.

[BuckoA51]

Cadence detection should always be off to put the VP50 into game mode and minimise input lag.

[rock145]

What is the difference between game mode 1 and game mode 2 on vp50 pro. Do they have the same input lag or is one faster than the other?. In which cases are these game modes used the most ?.

Hi. Could you post any/all settings you’re using with your VP50Pro/OSSC combo? I’ve got them myself but have yet to get anything above x2 working (although I haven’t tried too hard).

Does the VP50Pro manage to cover for the OSSC’s deficiencies with interlaced content any? I remember reading an old review for the unit that suggested it cleaned up old Sky interlaced broadcasts very well.

Hi, I have the default ossc settings I just set it to line 5x. I think you should first try to get line 5x with ossc and tv without vp50 pro. With my tv I was able to get line 5x with ossc without problem. Then if you get the ossc in line 5x with tv then try it with vp50 pro combo. From what I read if your tv does not take in line 5x with ossc alone the max you came get with ossc+vp50 pro is 3x. The only real thing that made a difference with vp50 pro was disabling cadence on vp50 pro.
