Demul is usefull only for Atomicswave.

for dreamcast NullDc is really faster, more games working, Demul don't work if you have a graphic cards that don't support DX11. Demul is full of bug (Yeah I m agree NullDc isn't perfect too), and at every update it s a surprise to see if your olds games are still working.

Atm Demul team is working on ikaru system (they are the only one on it, mame have integrated theses bios to but mame isn't the top for 3d game), wait and see....

Demul team aren't good, lot of ambitions but never do nothing, they start lot of projects but never finished one (like for model 3).

Now they stop working on graphic cards that don't support DX11 because it s  too hard for them, No problem for nulldc team.

Same for naomi game, better idead to use NullDc naomi version.

NullDc team is really better, look at their google code page, they really work on their emulator.

try to type "nullDC demul" on youtube, to see comparaisons.

You can trust me, I have work on demul to put it on my "playing machine" just some weeks ago.

I played it on XP so DX9 (Nvidia 9800 GT, so a 5 years old card). DX 10/11 aren't supported on XP.

NullDC is fine but not for long game/games with saves in my opinion.

Shenmue couldn't be finished on NullDC (the save crashed during the first disc) but could on demul.

For the other games, I don't know but I can confirm for someone who would want to do it that Shenmue can be played from start to end on demul 0.5.7, which wasn't the case, for me, on NullDC.

I also tried "Virtua Tennis 2" because I'm curious and it works better in Demul (in NullDC, the pics are pixelised).

And so, I said to myself that if it could play near perfectly the biggest game (in technical terms) of the system, it might be the same for the other games.

Try the last Demul version ^^. I have the same graphic card than you (and win 7) on my "gaming machine", if you do that, you will have error msg. No more versions for your card (and mine).

NullDc have news version too, shenmue can be finished now, there is still an issue for save (quick save from my memory) but it s possible with good parameter. Try that with pal version

Saving issue is very simple to solve if using the PAL version:

Ensure Patch GDRom Region is enabled
Go to Options > NullDC Settings
System region: EUR
Broadcast region: PAL

I had the formatting error at first but it now saves just fine.  Hope this helps someone.

For your pixelised image, try to change adjustment/filter. Virtua tennis 1080p on NullDC on HD http://www.youtube.com/watch?v=VZ9PNDq5CDE
Dreamcast displays interlaced or progressive scan image at 640 × 480 video resolution. So without
adjustments if you see pixel it s normal.
