Yabause 0.8.0 Released!

[BlueCrab]

Well, its my turn for a Christmas release, and for that I bring you Yabause 0.8.0! For those who don't know, Yabause is a multi-platform Sega Saturn emulator. For the first time, I have a Dreamcast release ready at the same time as the other ports of Yabause.

To download the newest release, go here:
http://yabause.sourceforge.net/index.php/?page_id=4 .
If you pick the Dreamcast version as listed there, you'll get the plain files for the emulator (1ST_READ.BIN). You'll need a Saturn BIOS image to go with it named saturn.bin in the root of the cd. After that, just burn it like any other selfbooting emulator, pop it in your DC, and follow the directions on screen. Performance wise, you'll get somewhere between 4 and 8 FPS most places, but only around 2 in movies. Not all games work, and some work in the PC version that will not work on the Dreamcast version. Sorry about that.

Here's some screenshots for those who haven't seen them:

These are all from the game Magical School Lunar, by the way.

Anyway, Merry Christmas, and Happy Holidays.

Woot! :) Thank you and happy hollidays Blue!

[WHurricane16]

Cool beans :) I'll have to check this out!

[Cap'n 1time]

i was shown this the other day.. still makes my mouth water.

[аlex]

Good news, :) but emulator very slow and no sound. ):

[Cap'n 1time]

Good news, :) but emulator very slow and no sound. ):

and yet its till the furthest ANY console has ever come to emulating a sega saturn (that i am aware of). this will still take alot of development i imagine, but with people like bluecrab working on it, im sure it will be worth the wait :)

[pang1978]

Great News BlueCrab.
Thank You

[RockinB]

I've been waiting for this for sooo long, thank you BlueCrab!

[JKKDARK]

Thank you, BlueCrab!! It's the best for the christmas :)

[BlueCrab]

Glad I could make some people happy. :D

2 BlueCrab
will in the future new versions of emulator on DC?

[BlueCrab]

There should be new versions in the future, yes. I intend to keep working on Yabause as time permits me to.

[kittenluvermeowz]

Can You give me a tutorial on how to how to burn it.

[BlueCrab]

I doubt it'll be much help if I do.... See, I use Mac OS X, so unless you're on a Mac (or on Linux), it won't be much help. I'm sure it'll work just fine with most of the homebrew burning applications out there (like Selfboot (http://dchelp.net/Apps/Selfboot.exe)). Just make sure you put the Saturn BIOS image (which I can't provide) on the disc with the 1ST_READ.BIN (and make sure the BIOS is named saturn.bin).

[kittenluvermeowz]

and is that dos MY COMPUTER HATES DOS!

and what does

Yabause is written in C using KallistiOS. So, in order to
compile it, you need a working sh-elf targetted C compiler,
such as gcc and a working KallistiOS environment:

* http://gamedev.allusion.net

Once KallistiOS is set up, you should be ready to build
Yabause.

Uncompress the Yabause source archive, move to the newly
created directory, type "cd src", then "make -f Makefile.dc",
it will generate one binary: "yabause.bin" in the "src"
directory.

mean in the readme

[BlueCrab]

That's if you want to build the whole thing from source. I'm somewhat doubting that's what you want to do.

Unfortunately, I don't know that there are any burning programs that don't use DOS in one way, shape, or form for Windows. Someone who uses Windows may be able to help you (I don't use Windows, as I had said before).

[kittenluvermeowz]

OK thanks. I thought i had to do all that kind of words that don't make sence, And thats why i want a mac.:rofl:

[turnerl]

this is fantastic!!! great work something too look forward to in the future ... great proof of concept for the dreamcast!

[Christuserloeser]

Can You give me a tutorial on how to how to burn it.

I recommend BootDreams. There are some tutorials in our tutorials section here on the SEGA Console Forums:

[kittenluvermeowz]

I think I got it.:rofl:

[Darksaviour69]

nice one blue

[vbt]

Just coming for news about DC yabause :) Any WIP ?

[Christuserloeser]

Not since 24th of December:
http://dreamcast.dcemu.co.uk/cgi-bin/cfiles.cgi?0,0,0,0,45,71

vbt, do you think you could help with Yabause ?

[BlueCrab]

I should be able to keep up with the Linux/Mac/Windows version releases, at least for the forseeable future (judging that there isn't another major change in the way Yabause works any time soon). As for news between releases, I don't really have any right now. I've been working on other projects that I neglected while I made Yabause work again.

As a side note, it took me about a month to get Yabause's Dreamcast port to run again. It hadn't really been touched much since the last release I did, about two years before this one (due to lack of time on my part).

[Christuserloeser]

That's good to hear :) and thanks a thousand times for this release !

Still, one day this project needs a dynarec like byte swapper for the SH2/SH4 (little endian/big endian) conversion, and PowerVR accelleration. I'm really curious if and which games we could get to play at full speed with CDDA ^^

[BlueCrab]

It has PVR acceleration for all the stuff drawn by VDP1 already. Unfortunately, doing any PVR acceleration of VDP2 is practically impossible (I tried before this release... it ended up overflowing all my vertex buffers, and I can't increase the size of them much more than I already have).

As for a dynarec, when I get the time to figure out all the logistics, I will work on it.

Glad you like the release, as a side note.

[Christuserloeser]

Wow O_O I wasn't aware of that ! So that's the reason for the speed boost compared to your initial release and this version! Great work !

Hey, I didn't really want to ask you for doing it right now! I just posted it because I felt it should be posted.

[BlueCrab]

Wow O_O I wasn't aware of that ! So that's the reason for the speed boost compared to your initial release and this version! Great work !Actually, I think a lot of the speed boost is due to the fact that Yabause was completely rewritten from scratch between those two versions. The version before this also used the PVR for all the VDP1 stuff (the Linux version used OpenGL, and I pretty much used the same renderer).


Hey, I didn't really want to ask you for doing it right now! I just posted it because I felt it should be posted.I didn't think you were, sorry if it came off that way. Its been a long couple of days....

[Zion]

great job bluecrab, saturn on the dreamcast is what sega should have done from day one :D

keep it up mate :D

[Elven6]

This thing is given me some trouble, I have a copy of THe Lost Vikings, the first time I tried it the game worked out, but when I try it now it keeps saying it won't work.

[BlueCrab]

This thing is given me some trouble, I have a copy of THe Lost Vikings, the first time I tried it the game worked out, but when I try it now it keeps saying it won't work.It says it won't work? What exactly is it saying? If its booting anything at all, what is it doing?

[kittenluvermeowz]

this is crapping me out, I can make it say insert saturn.bin does it need to be a us bios, and does it need to be saturn.bin with the .bin showing or just saturn.

[Baboon]

I cant believe weve got a saturn emu for the DC. I look forward to future updates for this gem.

Downloading now. :)

[BlueCrab]

this is crapping me out, I can make it say insert saturn.bin does it need to be a us bios, and does it need to be saturn.bin with the .bin showing or just saturn.I've only ever seen the US and Japanese BIOSes used with Yabause, so those are the only two I know work. The filename has to be "saturn.bin" for the BIOS file.

Hopefully the replacement BIOS code that is being written for Yabause will be more usable for the next release, and we won't need the actual BIOS files to just run games.

[Elven6]

It takes me to the audio player and it says this disc is not playable or something similar to that.

[BlueCrab]

What region is the game disc, and what region is the BIOS file? I don't think its an issue, but I could be wrong.

That's quite strange indeed.

[Elven6]

Their NTSC, it worked the first time I tired it.

[BlueCrab]

Other than if the disc is scratched, I see no reason why it wouldn't work (other than a malfunctioning GD-Rom drive, possibly), if it worked before.

[Darksaviour69]

man i have to get round to trying this out, but all my sat games are at home

[kittenluvermeowz]

so it's just satur n if my computer hides the .bin

[BlueCrab]

If you're using Windows, there's an option somewhere in Windows Explorer called "Hide extensions of known file types" or the like. Likely .bin is a known type, and might not be shown. If you disable this option, you can find out for sure.

Also, if you use the MS-DOS Prompt (or is it Command Prompt now?), you can do a "dir" in the directory that contains the file to find out for sure.

Other than that, I haven't used Windows in the longest time, so...

//////////this is the worst emulator i've seen in my life..
Its horrorible...

[Mark30001]

Sure the emulator may not run at 100% speed, but BlueCrab has spent lots of his time creating what many thought was impossible. You must at least congratulate him on that. ;)

[Cap'n 1time]

//////////this is the worst emulator i've seen in my life..

Anyone that says this... probably doesn't realize that this is not a progress in speed. Getting games to run at a playable speed will probably be the final challenge.. The actual ability to get saturn games running on the DC, that is to say, making the emulated hardware work as close to perfect as possible is probably the first the primary goal, and there are many "sub steps" to complete before that will happen.

I hate people like this. They are willing to throw in their own worthless input, but have no idea whats going on.

This was a progress in speed actually. About twice as fast as the previous version.

[vbt]

There is no reason to give a such bad feedback, it's the first Saturn emu for dreamcast. The result is quite good and we all know that PC version of Yabause is one of the best Saturn emu. I will need a lot of time to optimize it for the dreamcast. SO we should hear mainly spport and constructive critism.

[BlueCrab]

//////////this is the worst emulator i've seen in my life..
Its horrorible...Gee, that really makes me want to work on it more.

Honestly, what do you think making this kind of post is going to accomplish, other than discouraging me from working on it? I've explained exactly how fast the thing runs many times before, yet you have to chime in with crap like this? People like you make me sick.

As a side note, I do intend to work on Yabause more, so don't think the lamers can discourage me that much ;) .

[iphicrates]

I Love you bluecrab!
i dont care about the speed!
p.s. does NiGHTS work on this yet by any chance?idc if it dusnt. I still love this! dont stop!

[BlueCrab]

No, NiGHTS doesn't currently work. It uses a video mode that I didn't have the time to try to implement before the release, and thus it exits the emulation (with an error, if you run it over a bba/serial cable).

its totally cool!just giving me something to hope for!
