Very slim chance, I don't know Z80 ASM at the moment...

Just released a new version of the suite, for all three systems.

- Backlit zone test: I created this to test LED backlit TVs, but should be useful in any setup. It is simply a black background with a variable size sprite, which you can move around. On a full backlit LED display,you can easily spot the zones and how they work.. it also helps you see how your tv handles such situations.

- Fixes the Linearity pattern to account for NTSC's pixel aspect ratio. Should be perfectly circular when processed as an NTSC signal.

Versions are 1.09 for Genesis and Sega CD, and 1.12 for Dreamcast.

Hi, want to say great job with this.I just finished fixing up a candy cab, so this will come in handy down the track.I figured this is probably the best place to suggest/ ask.Would it be possible to make this disk asa boot disk, that forces the Dreamcast into a 240p resolution mode?With Street fighter 3rd strke on the Dreamcast you can hold L + Start at the Capcomlogo and the game will go into the arcade resolution, would it be possible to get the code that does this and put it into this application/ and or create a patcher for DC games that don't have this mode such as Super Street Fighter 2 X.Maybe it wouldb't work, perhaps it might.Anyway it's a suggestion and one that if it worked as intended would be fantastic.Since we can patch VGA modes into DC games and add 60hz options,perhaps we can get a Arcade perfect res boot disk.If I could code, I would do it myself.Love to hear what you think.Thanks.

That is game dependant, since this is a stand alone application developed with KallostiOS on DC. In order to enable that, you need to rip the games, patch the images and play those patched images.

Quick suggestion, adding a controller test to both versions would be quite useful.

Has nobody ported this to the Amiga yet? I'd imagine a port would be easy for anyone with 68k programming skills (my skills stop at C, sadly :oops: )

Will do, thanks for the suggestion =)

BTW, there was a new release of the Genesis version. It includes a frame counter useful for lag tests, specially with a Nomad since real lag can be measured with photographs. The Lag in my modded Nomad display is 1 frame.

I would need a 60fps camera for this correct? My camera only does 30fps unfortunately.

Yes, but you can use a photo camera set at 1/60th of a second.

You should go down as far as possible with the exposure time. If your digicam has a sports mode, that usually works great... The old stock Nomad display lags a little less (7.5-8ms). Just take a few dozen shots and average the differences you see.

First off, thanks for creating this tool. I've used the Dreamcast version in the past, and it was exactly what I needed.

Did anything ever come of the Saturn version? I would love to make a Saturn display some color bars, but I've been unable to find a way to accomplish this.

On the Saturn you can use the JVC Photo CD Card to display patterns created on the PC or you create all the patterns you like in Dezaemon2. The JVC card displays in interlaced hi-res. Dezaemon displays in low-res.

Thanks, I am glad the DC version has been of use.

And no, I haven't done any progress on the Saturn version, I have yet to find my USB transfer hardware to make development easier than burning CDs. I have one, but am not sure where I placed it. I am sure to do some work in the future, but have not started as of now.

Fudoh's suggestion can help if you only need to do that, just kee in mind the Saturn's palette. The Dreamcast pattern available in my source coe can help you there.

If you're still into the Saturn, you may want to check this out. Cafe-alpha over at SegaXtreme should still have a few assembled boards available for $42+postage.

Thanks a lot for the heads up. I love the Saturn and was a regular at SegaXtreme a decade ago... I don't know why I've gotten so distant with it, loved the community. I enjoy these kind of developments a lot.

Some updates to the suite.

Version 1.16 for Dreamcast is up now, along with 1.10 for Genesis/Sega CD. They mainly incorporate a 100 IRE test pattern. In teh Dreamcast version it can be set between 0 and 140 IRE in 10 IRE intervals.

It also includes support for a lag test using the Dreamcast microphone, the SIP. When connected, a new option appears in the menu and enables very accurate lag measurements via audio. However, this requires the Tv to lag the audio the same as the video to be precise. I still have to do some work in this feature since it only runs correctly when ran via serial cable or ethernet, for some reason it doesn't work when run form a CD.

It uses a Fast Fourier algorithm to determine how many frames the sound is recorded after playback.

the term alone makes me shudder. Fourier transform was the single most disgusting thing I had to learn in university (and hey, I studied economics and law!).

PS: nice work, as usual !

I'm trying to run this on my US Sega CD (model 2 side loader w/ model 1 Genesis) and it just freezes at the Sega logo with Sonic. I've burned it at 1x 4x and 16x (the recommended speed for my discs) and it still doesn't work. Once it got past the Sega logo, but just went back to the CD dashboard.

I also cleaned my laser lens with alcohol, and it runs other games just fine.

I'm using an RGB cable & YUV to component box, and the headphone jack for audio, in case it matters.

Edit: Hi Fudoh! I'm trying to assess my picture situation with my current setup, while I wait for my iScan Pro and SLG HD= to show up! :D

Then I can do a before and after comparison....if I can ever get it to run, lol.

I've not experienced or had a previous report with the Sega CD version before, I am sorry this happened.

Have you tried running your disc in an emulator, just to check the data in the disc is correct?

I use exactly the same kind of setup that you do for my tests. Have you tried running other burnt CDs on it?

I just tried a burned copy of Keiyo Flying Squadron just to test how my machine runs burned discs and it worked just fine. I'll see if I can run it in Gens. Was the newest version tested on that same hardware?

I tried the latest in a CDX, so it *should* work fine. The latest tested in my model 2 was 1.09, but there shouldn't be any difference in the bootloader between that one and the newest.

Could it be that my laser doesn't like to read that far in? Any way to pad the disc? I tried it in Gens with the v1 bios and got the menu and the little Seedling on the right. ;)

Burned games work fine on my machine....I don't get it. :roll:

Edit: It's burning in Mode1/2048, is that right?

Edit 2: Downloaded and burned 1.09, same thing.

It is indeed weird. Please wait for 10 hours, I will test it back at home and detail everything so you don't waste any more discs.

That's cool, thanks. :) Actually I was inspired by your avatar and the test suite screen to see what Snatcher looks like in RGB/Component, and it looks pretty damn sweet. I'm just standing in the Junker waiting room trying to sexually harass Mika at the moment. I love this game, lol.

It is an awesome game =)

I am sorry about all the trouble... and delay. My HDD is crashing constantly, it is giving its last.

Due to this I could only recompile it here and could not perform a full test, but here is a rebuil.. I hope it works for you.. let me know: https://dl.dropboxusercontent.com/u/140 ... CD_USA.zip

I cannot do anything more until I get a new HDD. I am terribly sorry.
