Emu#dreams reports that byuu has been working on bsnes, the Super NES emulator, some more. Below is his post on his homepage about the recent work.

Updated the DirectDraw renderer. It also has perfect triple buffering support now. That's good, because the DDraw renderer is way the hell faster. The only thing I really can't do with the DDraw renderer is allow luminance in the scanlines. No hardware accelerated alpha blending, you see...

 

Also improved some of the Direct3D code. You can now specify the raster size in the config file. You can also switch between the DirectDraw and Direct3D modes inside the config file now, too. Hooray for virtual base classes.

 

I also improved the scanline rendering, a lot. I'm still planning some of the final details there, so no screenshots for now. Let's just say... I've found the perfect screen resolution: 1792x1344. Try and guess why that is. I'm planning to write a document on proper TV-style scanlines on CRT / LCD monitors, so I'll explain that resolution more there.

 

Lastly, I forgot to mention this the other day, but I also revamped the joypad support. bsnes now supports up to 256 joypads, and up to 128 buttons + 4 d-pad buttons for each joypad. I also revamped the d-pad support to check the POV hat. So now you can use the controller in digital or analog mode, and the analog thumbstick is way more responsive. It makes pulling off combos in games way easier. I'll probably make this a configuration option because it definitely has room for calibration.

 

I also fixed a major problem with interlacing. Before, I was allowing interlace to be toggled mid-frame. But that's not really the case. What threw me off was that the rendering appears to be interlaced when you enable it mid-frame, but it's really not. It's just skipping every other scanline, just like interlace mode would. However, the screen is still only rendering the even scanlines. A quick test confirmed this. Thanks to TRAC for pointing that out initially. bsnes will now only update the screen interlace setting every other frame. I still need to test on hardware to get a more exact position for when this actually occurs, but this will work for the immediate present. This also makes screen rendering a hell of a lot easier on me. Hooray for that.

 

Oh yeah, and I heard that bsnes has more responsive input than some other emulators... so for that, I moved the PPU screen rendering to occur at V=240, instead of V=0 (the screen is rendered sooner, basically). This should make the controller feel infinitesimally more responsive. I don't notice the difference even in other emulators, but maybe those people will.

AEP Emulation Page reports that Mocha, the Java-based TRS-80 Color Computer (CoCo) emulator, has been updated. Below are the release notes for version 1.13.

- Mocha now remembers the file path when opening a new cassette, bin or dsk image in the signed applet.

- Various optimizations - inlining, etc. As always, the Java 1.1 version is probably faster on slower machines.

You can try out Mocha here online, at the official homepage.

AEP Emulation Page reports that NEOGEO CDZ, the Japanese Neo Geo CD emulator for Microsoft Windows, has been updated today. There wasn't supposed to be another update until January, but this comes early. Below are the release notes for this version.

Bug Fix

- With the bug of reading and writing of backup memory, being to have the possibility where it cannot start with application error it corrects.

 

As for this version because of the version which is the continuing resolution, there is a possibility trouble occurring. Because correction method of the source is written on the page of information of development, if it is possible, referring to there, please do the correction of 2005.12.14 sources with each one.
