Advice on burning for PAL Dreamcasts ( Flickering problem )

curious.au · #1 16-12-2002, 14:48

Hi.

I was wondering if anyone could give me some advice on burning images for my PAL rev 1 Dreamcast. So far, I have burnt two discs for it - Utopia Boot 1.1 and Ikaruga. In both cases, the CD's boot fine, but flicker like crazy once they've passed the Sega Logo area. ( It looks like two or three images are squashed vertically onto the screen, or something like that ) - the result is unplayable, unfortunately.

Ikaruga also throws up with a Disc error, but I suspect this is because I ignored the .nfo file and burnt it with cdi2nero instead of DJ4 - my bad.

So, is this flickering an indication that the DC is spitting out NTSC video that is making my TV throw-up? Can I patch around it ( or am I patching incorrectly? )? Do I need to adjust some parameter on the Television, such as Vertical Hold ( I thought of this after I left the house )? Do I need to lay my fingers on some kind of converter, or a VGA adapter?

I didn't think it was the vertical hold because Bust A Move 4 ( original ) plays fine. Anyway, if anyone has any advice for me, I'd really enjoy it.

I just had a bad thought, and quickly checked around and found that PAL is 50Hz and NTSC is 60Hz, not the other way around, as I thought.

So I think the problem is that I am very, very stupid. :-P

Well, I thought this would fix it, but sadly no. :-(

I opened the discjuggler image with PAL Patcher 1.0, selected my Ikaruga (Jap) image, set the 60->50 box and PAL Protection 2, scanned it, highlighted the PAL Protection item in the list, and hit patch.

I then converted it to a nero file and burnt it. The result was a disc that actually plays ( I can start games, etc ), but still looks like its stacking three screens vertically onto one, and flickering horribly, and is generally impossible to play with. This is a real bummer, as I don't think there's any other way I'll ever get to experience this great game. :-(

Can anyone think of something that might help?

Open your original image with an hex editor.
Look for D20B420900011F0C84
and replace it by D20B420900011F30E0

Thank you so much for your help, Lexxx - I owe you. :-) However, I had no joy from that patch. :-/ First, I patched the CDI file, a fresh copy, checked it, converted it to a nero image, and burnt it. The result was a CD that went straight through the the dreamcast menu, as expected, and if you selected "Play", made the screen go black, and then rebooted.

I am told this is a symptom of the "PAL Protection", so I fired up PAL Patcher and scanned the CDI, finding PAL Protection types II and III. I patched both, but left the Hz settings untouched.

This CD booted, but still had the same problem - three images being crammed on the screen vertically - very unfortunate! :-/ All the same, I thank you for trying.

Do you think I will have these sorts of troubles trying to play other games? Just to be on the safe side, I ordered a copy of Dead Or Alive 2 from Ebay today, so hopefully I'll have something to play while I learn about patching. ;-)

I have plenty of CDR left if anyone else would like to suggest an experiment. :-) Perhaps in time I should try and write a SH commenting dissassembler.

If anyone can answer: I have heard there were CD's for playing Imported games available in the US. Did such CD's exist for Pacific / Europe PAL machines? If so, what were they called? Perhaps they are my best bet.

I have 1 suggestion : burn CDI images with DiskJuggler !!!

I have a PAL DC.
I had the same problem than yours with Ikaruga.
"PAL protection 3" is the one I just gave you.
Ikaruga plays fines now on my TV.
So there's no reason why it wouldn't play well on yours...

Well i will tell you what i did with Ikaruga...might be helpful,maybe not.

I got it 6th Sept,and Megalexxx soft didnt support it yet. I burnt it with DJ 3.50.05.830 + LG 8080B using the default settings.Soon i noticed it was 50hz,i have PAL Dreamcast + RGB.

I used this patch

and burnt again,worx perfectly in my 2 dreamcasts

If this still doesnt work for u,try booting the game with Utopia,ActionReplay/Gameshark.There are images of them in megagames.com

Thanks Enuff. I had a look at this patch, and I'll give it a try, but I've realised it might be worth mentioning that my rip of this game is not necessarily the w00t release, but the one from Sharereactor. I didn't think this would make much difference, but now I'm not so sure. It's quite possible the releaser patched the hell out of it already.

I noticed that the patch there says its an NTSC to PAL converter patch... sounds like the opposite of what I want, but I'll give it a go anyway. And I now have DiscJuggler for burning the image with.

Thanks for all the help, guys. :-)

As for the Gameshark and AR, I have images of both, but the AR requires special hardware, and the GS a VMU - Mine is currently in the post. Does the GS require anything except a VMU? Perhaps this could be my lucky way out. ( Then again, perhaps I should just start looking for the w00t release... I wonder what it's ed2k:// signature would look like... )
