|  A new version of VICE is out
After a long and marathonic beta-phase, version 2.3 of the popular multiplatform Commodore 8-bit machines emulator has been released yesterday. Here is the full list of changes having an impact on the plus/4:
** General
- Added x64sc, the accurate C64 emulator:
We believe x64sc is one of the most accurate C64 emulators at the
moment.
- Drive improvements, including weak bit emulation.
- Major reSID overhaul:
* Emulation of all known pipeline delays for full cycle accuracy.
* New shift register model based on revectorized die photograps.
* Accurate DAC models based on revectorized die photograps.
* Emulation of floating waveform DAC input for waveform 0.
* Advanced 6581 transistor level filter model based on revectorized
die photograps, yielding unprecedented accuracy.
- CRT Emulation (former "PAL emulation") is now available regardless of
video mode or -chip and works in all emulators.
NOTE: Color gamma range changed. You may need to set to 2.200 manually.
(ColorGamma=2200)
- Added "True aspect ratio" option.
- Sound buffer overflows reduced and the error replaced with a warning.
- Various monitor improvements (io details, expansion port status ...)
- Removed little used Emulator ID feature.
- VIA wrap handling rewritten to fix problems with timer 2.
- Added autostart option to do LOAD ,8 instead of ,8,1.
- Improved accuracy of CIA interrupts. (6526/6526A selectable)
** PLUS4 changes
- Fixed crashes in NTSC mode.
- Added v364 speech emulation.
As you can see, VICE folks have also implemented the emulation of the Toshiba T6721A speech chip and it is now featured in the plus/4 emulator.
Head on over to the Sourceforge webpage here. At the time of this writing only the source code is available, but a question of time and the binaries will be up there as well.

...which still emulates the $fd30 keyboard SPI incorrectly (...after so many years, OMG!... :o ). Gonna report the issue to the developers ASAP.

Well, the plus/4 port is more or less abandoned  Actually, I'd rather have someone make a cycle based engine from scratch like the x64sc.

And since I can't even compile the plus4emu dependencies (they're many, they're beardy, and they're old) I have to settle for youtube clips of Plus/4 releases these days... sucks :/

Interesting, good to know.
I don't have X11 installed anymore though...
