Dreamcast Widescreen Hacks

For Half life I've found some values for the camera, most controls zoom values, but nothing that makes the game widescreen, the game does clip heavily outside the intended renderable area, so even puting the camera further away will result in some awful clipping.

I know there is a widescreen hack for the ps2 version ( even if that version already has a 16:9 option) so I'll keep searching for some usable value.

 

Well that is unfortunate about the geometry but thanks for looking into it. Much appreciated.

 

Alien Front Online v1.000 (2001)(Sega)(NTSC)(US)

Code:

You are on fire, Esppiral! Somebody stop him, he's a machine!

I've tested your Dead or Alive 2 code and the WWF Royal Rumble codes on a real Dreamcast, and can verify they work. I don't know if it's from the codes, but when you pause the game in WWF Royal Rumble the characters stretch vertically (and they might be squashed in gameplay). I'll test it some more to verify it, I've been a bit rushed due to Valentine's Day. I also have to test Suzuki Alstare on a real DC, but I will definitely get it tested.

I've updated the list with Esppiral's latest work.

 

Nightmare Creatures II v1.000 (2000)(Konami)(NTSC)(US)

Code:

02CDE844
3FA00000

 

I don't know if you saw it, but there is a very good news: there is a new RC4 of DreamShell!
Now it's completely open source, and among other things there is a widescreen display mode for the menu, and an interesting option in the ISO loader:

 

A bit offtopic, but do you know how to run latest demul 0.7 with directx10? My gpu doesn't support dx11 and demul 0.7 crashes.

 

It's should be like that (if Shenmue ii code as example)
original:

Code:

0231186C 43700000

Dreamshell:

Code:

--pa1 0x0C31186C --pv1 0x43700000

i'll test it later and upload screens/videos from original hardware

 

I need to start using my games in widescreen mode on my real dreamcast ( never considered using an emulator apart on android)
Thanks for your great work

 

Mh, sorry I have an R9 270X so it is a native DX11.1 GPU so not sure about DX10 plugin. :/

 

And demul 0.7 refuses to use the dx10 plugin from the previous release..

Updated the Codes Listing, including Mr Driller and Street Fighter 3rd Strike (which has a note on not being centred yet).

I haven't been able to test out Suzuki Alstare as my disc (which barely worked when I bought it a few months ago) now refuses to load a race. You go through all the menus and it will then try to load the race before returning you to the menu, there's obviously a disc reading issue. I'm getting a replacement disc next week so I'll test the code when it arrives.

You're doing excellent work Esppiral, only one question - what region is your Street Fighter 3rd Strike? You didn't state if it was JP, US or PAL.

Edit: new Suzuki Alstare disc ordered to replace my faulty one. Hopefully it should arrive in the next few days and I'll update on whether the code works on console.
Esppiral, is there a way of stopping WWF Royal Rumble from squashing the characters vertically?

 

Sorry for the double post.
I've bought a new copy of Suzuki Alstare Extreme Racing and can confirm the code works perfectly on a real Dreamcast with no slow down or negative effects. That being said I'd now want to hunt down a no clipping code for it, as some of the clipping in the game is quite bad.

Has anyone developed a help guide for testing codes in an emulator? I really want that (and many other) codes.


EDIT:: URGH. Remembering why I absolutely despise emulators. They never bloody work, even just to PLAY games, for some reason they never install in any form of actual usable condition.

So I have downloaded demul, but any time I try to boot a game it just gives me an error message saying "Unable to find 'mpr-21871.ic501' in romset 'dceu'". I have no idea what this means, I can't find an English help guide online to tell me what that even means, and the emulator refuses to play at all.

I then tried nullDC, which plays games but has no codebreaker inputs. I really need someone to help me figure out what is going on so I can actually test some codes, it takes far too long on real hardware.

 

Can this be done with Sturmwind and other Indies too?

 

You got the dc.zip in the roms folder?

 

try to google "Demul BIOS Pack".

 

Okay, it's now booting up game, thanks guys.
It's got issues with slowdown and audio problems though. Sounds like the audio is going through water.
I also can't find the Codebreaker windows that Esppiral has been using in his pictures to test codes out. Any ideas guys?

I have a 5 year old laptop, on Windows 10. 1.4Ghz, 8GB RAM and a GT650M graphics card. I'm unsure if it has the grunt required, but I'll keep on trying. If worst comes to worst I am building a new £2k rig at the moment for 4K film editing purposes with 32/64GB RAM, 3.4 Ghz Haswell processor and a GTX960 (eventually two of them) with 4GB RAM each - I'm guessing that would have enough grunt to test some codes lol.

 

For emulation the GPU isn't what is really needed to be super powerful. As long as the card is newer it is compatible. I used to have a 650 desktop GPU and used to be able to play all newer games ok with it. Obviously not on ultra but it is still modern architecture and a DX11.1 gpu. You however do need a much more powerful rig for emulating games with Demul, whereas NullDC was more optimized but sadly dropped official support around 2011. I was emulating Dreamcast in 2008 very well on NullDC. So even with my ancient dual core specs at the time it was able to play games in HD.
