Yabause 0.9.5 Released

Post by BlueCrab » Sun May 11, 2008 5:54 pm

The Yabause team is happy to bring everyone a new release today. 0.9.5 has many bug fixes, and other code changes. This time though, I actually had a chance to put together a Dreamcast release too, and there are a few Dreamcast-specific changes this time too. This release has an entirely new CD core for the Dreamcast that is written in hand-optimized assembly. Sadly, optimizing the CD core doesn't do much for speed overall, but it was good practice.

As for what has changed, here's the ChangeLog:
0.9.4 -> 0.9.5
68k:
- Added 1010 and 1111 line emulator support.
cd block:
- Reworked bin/cue support. Reading should be a lot more accurate
now on tracks 2 and greater.
emulated bios:
- Fixed a bug in BupGetDate year calculation.
- Fixed a bug where interrupt mask wasn't being set correctly when
using emulated bios.
smpc:
- Added support for SMPC NMIREQ command.
- Added reset button emulation.
software video core:
- Improved software renderer: window, line scroll, mosaic are now
available and color offset and scroll screen has been fixed.
gtk port:
- Tagged most of gtk port strings to be translatable.
qt port:
- Added ability to specify address where binaries are loaded when
using command line.
- Other bug fixes.
wii port:
- Added support for bios and game loading from sd card.
- Added sound support.
- Added usb keyboard support.
windows port:
- Added pause emulation function.
- Other bug fixes.
dreamcast port:
- Rewrote all of the Dreamcast CD Interface in hand-optimized
assembly.
- Enabled use of the emulated bios if there is no saturn.bin on
the CD.
general:
- Updated peripheral interface so both ports can now be used and
multiple pads can now be connected to each port.
- Added translation support through mini18n library.
Yabause 0.9.5 can be downloaded from http://yabause.org/download/ . Currently, binaries for Dreamcast, Windows, and Linux are available for 0.9.5, with the Mac OS X version soon to follow (hopefully).

Great work, I just downloaded it.

So the speed hasn't changed at all or is it a bit faster?

Only for CD-ROM reading, if anything.

It may be a bit faster, but its not anything at all noticeable (so if it is faster, its by a factor of something like 0.1 FPS).

Yabause is more a proof-of-concept than a real emulator. Most games are extremly slow. You can use BootDreams to make a selfbooting image.

As of 0.9.5, you do not need a BIOS. As for a good game to test it with, any actual Saturn game you have should do at least something (NiGHTS does not work though). I usually do my testing with Magical School Lunar.

There some instructions on burning Return Fire on on the same disc as Yabause in one of the older release topics:

viewtopic.php?p=967172#p967172

The only difference is that you can load the cue file in the newest version of BootDreams (currently 1.0.6c) instead of burning it manually.
