Finally, I managed to merge
the PAL and NTSC builds which means that a standalone NTSC build is not
needed anymore. It was a crucial step, as many of you may know, the TED
did not have separate PAL and NTSC versions. By appropriately setting
one of the registers, one could choose the proper chrystal clock
divisor for its system. Although this did not make your machine behave
like the other standard, some tricky demos used NTSC mode for their
high frequency digi music. These should sound next to perfect now.
Anyway, this is basically all what's new for now, so I am not gonna
detail the changes here, see the attached Changes.txt if you're
interested. The new release is available on
this page as usual.
Yape
0.59 is here with multiple drive support
25/9/2004
After a mere three
weeks,
another new version of Yape/Win32 is out. There has been a lot of
improvements as well as one cool new feature has been implemented too:
the possibility to add up
to 4 truthfully emulated disk drives to the virtual machine in all
imagineable combinations (within the possibilities of the 1541/1551
range of disk drives, of course). Here's a full lowdown of the changes:
support for up to four
truly emulated floppy drives
support for multiple drives in the external monitor
support of D64 files with up to 40 tracks
saving in halfwave TAP format was broken since a while
A new version is out after
some break. Here is what's new:
selectable fullscreen modes
selectable TED sound oversampling rate
improved snapshot handling
many TED related improvements
fixed a crash in the monitor
correct addressing mode for illegal opcode $D7
Get your copy from the download
page. Note, that the open source SDL version (for Linux, FreeBSD,
BeOS, Solaris etc.) has also been updated. Although it is still the
very old codebase (from version 0.32), there has been a few SDL related
improvements made. I am planning on giving a major face-lift to it, so
keep on eye on the page if you're into the SDL version.
NTSC version of Yape
0.57 available
25/6/2004
I have been playing around a
bit with NTSC support and here's the result: a preliminary NTSC version
of Yape has now been made available on the download
page, so don't hesitate to grab it if you're after an NTSC
Commodore plus/4 emulator as Yape is the first plus/4 emulator with (a
working) NTSC mode! The PAL and NTSC versions will be at one point
merged into one executable, in the meantime, you must download them
separately.
YAPE 0.57 out
16/5/2004
This new release has most notably far better SID card
emulation. For the first time it will also be possible to switch over
to the original clocking of the SID chip that will in itself already
result in a much better quality of SID music as usually 99% of the SID
tunes were originally not made on a plus/4 (exceptions being most of
the tunes done by
Luca) and playing these on a different clock frequency than the
original may usually provide incorrect pitch tones, filter and ADSR
effects. But let's see again what else has been added in this release:
synch frame rate to that of the monitor
new monitor improvements:
command history
debug with step over
implemented the HOME and END keys
some TED sound optimisations
selectable SID-card clock frequency
many bugs in the external machine code monitor fixed
big improvements in the SID-card emulation:
new combined waveforms
ring modulation for combined waveforms
noise waveform fixes
more exact IIR filter emulation (different
cut-off frequencies for 6581 and 8580)
This
0.56 version fixes a couple of bugs and glitches that were making
their way to the previous release, and introduces an option to select
either the Windows messaging or DirectInput for keyboard and joystick
emulation. Latter is cycle exact but for compatibility with older
computers an input method with the trusty old Windows Message Queue is
also available. Get your download from here.
YAPE 0.55 released!
7/3/2004
This new version
brings you the following:
cycle based TED and SID sound
WaveMapper sound option
cycle based keyboard & joystick emulation (via
DirectInput)
improved a few SID waveforms (noise, triangle)
tweaked clocking of the 1541, even more disk turbos
work
enhanced the autostart feature
bitmap fetch reload fixed
a couple of bugfixes
Head on over to the download page for your
copy, while it's warm :-)
YAPE 0.54 out with
full disk write support!
9/1/2004
Happy New Year
everyone! Let's kick off this year with a brand new version of Yape.
It's special in a way that it sports two very important features: full
write support in all drive emulation modes plus optional combined TED
and SID sounds at last. No annoying switches between the two sound
options are necessary anymore. Finding a long standing bug in the disk
rotation emulation made it possible to implement full disk write
support. Even turbo copiers and fast formatters work from now on!
Anyway, let's see what this new year's first release has brought us:
true disk rotation emulation
full write support in CPU level 1541 and 1551 drive
emulation
TED and SID sound now selectable at the same time
option to synchronize to Vblank for smoother video
improved reading of SID registers
better high and low pass filters (courtesy of
Bionic)
maximizing the window in PAL mode now keeps the
correct aspect ratio
potential timer overflow bug corrected
stupid & rare crash bug in cpu emulation fixed
emulator ID could cause custom ROM corruption
many-many bugfixes
Note that for now, Yape will make a backup of your D64 with a BAK
extension when the image gets changed. The screenshot is showing Bard's Tale III
one of the few games that requires proper true drive emulation along
with write support and has failed to work. Until now :-) Get this new
release from the download page.
