A new version of Yape is out
with the following changes:
- tape counter in the status bar
- joystick fire on PageUp key (for laptops)
- TED and SID mixed sound can now also be saved to
AVI/WAV
- fixed full screen mode autodetection
- stupid new bug in 1551-IEC/filesystem mode fixed
- fixed a potential crash and clicks on recording to WAV
- zip support got accidentally disabled in 0.68
A couple of nasty bugs have made their way into the emulator the last
months due to the hasty pace of development, the most annoying ones
have been fixed now for good (hopefully). Thanks to all who pointed
them out. Get
the new version from here.

Just a small piece of update.
A while back I have made a complete
disassembly of the Commodore 1551 parallel disk drive. The comments for
the DOS part are
taken from the Complete 1541 disassembly by Frank Kontros, the rest was
added by me. It is a very handy piece of stuff for people willing to
learn how the 1551 actually works. You can download the first revision
from this page.

| Yape 0.68 with "THE"
magical voice is here! |
10/09/2006

 What
seems like a minor update is actually a huge achievement, and
again my emulator has become a first-timer with the Toshiba 6721 speech
LSI
emulation. As you may - or may not - know, this chip was featured in
the V364 prototype
as well as in the actual production "Magic Voice" cartridge
unit for the Commodore 64. Yape has been having V364 support for a
while,
but the speech had relied upon Windows' built-in Text-to-Speech API and
as such was not to be called real emulation, rather "simulation". The
almost total lack of documentation regarding the T6721 LSI rendered the
truthful resurrection of this prototype almost hopeless. Yet, years
after my first call
in 2000 for researching the V364, it is now reality! Not all aspects
are clear, of course, but enough to get the built-in speech working and
with excellent quality. Check out Bo Zimmerman's V364 page - it has
all the original WAV recordings - and hear for yourself! I'll put up a
page soon
about programming the Toshiba 6721 and a few hints on how to create
custom speech with it. I have loads of ideas:
- making a Magic Voice modul for C64 emulators
- designing & building a "Magic Voice" cartridge
for the plus/4 that is compatible with the V364 prototype ROM program
(volunteers?)
- porting the cartridge version of Wizard of Wor - that
featured speech - from the C64 to the plus/4
- creating custom speech from WAV files
- using the T6721 chip for music (after all, it has
pitch control, a 10 stage filter, white noise & triangle wave
source and 15 bit digital output). At the very least it should be
possible to do digi playback with it!
Anyway, enough of the hype, here is a list of all the changes in this
release:
- true Toshiba 6721 speech LSI emulation (custom
vocabularies works, too!)
- performance mode for very slow PCs
- separate drive reset
- bugfixes
Let's not forget about another very cool feature: the performance mode.
In this mode (to be found in the Machine settings dialog window) Yape
will sacrifice some TED accuracy for sake of more speed, in general you
can achieve 2-3 times higher speeds depending on the actual situation.
However, you are unable to use true drive emulation in this mode.
Get this new copy from this page. Also
check out Clickgamer's plus/4 page here where version 1.1 of my
plus/4 emulator for the Pocket PC has recently been made available.

| Version 0.67 of Yape
out |
9/07/2006
|
Small(ish) update this time. A
few nasty bugs have been fixed, and the TED chip compatibility has been
improved upon (not really noticable, unless you're a true demo-geek).
But let's see what's got added this time:
- improved TED chip emulation
- some class refactoring (not visible to end users,
mainly intended for future portability)
- a bit more consistent GUI
- unused 7501/8501 processor port bits bug fixed
- disk corruption bug (after formatting) fixed in true
drive emulation
- rare 'save as PRG' dialog crash fixed
I forgot to mention at the last update that the XP theme support has
also been added, thanks to the fact that I have finally upgraded the
Yape project to the latest version of the compiler. You can get your
copy of Yape here.

Even though Pocket C+4 has been the main
focus in the last couple of months, I haven't forgotten about Yape
either. This time the following additions have been made:
- more than one (up to 4) 1581 drives now possible
- one-shot breakpoints in the monitor (U $address, or G
$start $stop)
- resizable emulator window in DirectX mode
- resizable monitor window
- actual memory reads/writes now shown during debug
- synch to vblank functionality changed
- cleaner code and better optimizations
- small bug in SID noise waveform fixed
- memory leak in fake drive emulation fixed
As you can see quite a few improvements have been made to the external
monitor. One-shot breakpoints are extremely useful when you want to
debug your code, think of it as a 'Run to cursor' equivalent. Download
Yape 0.66 from here.

Pocket PC owners, that wait is
over! In the last couple of months I have been busy revamping my Yape
emulator for the Pocket PC platform: a real challenge! Although the
Pocket PC's are getting ever more powerful, their CPU is still only
comparable to that of the desktop PC's of the late '90s. Still managed
to achieve a very good speed and compatibility. It will also support
today's most advanced VGA devices in their native 480x640 resolution.

Good news is that Commodore Inc
has officially endorsed this product, so it is going to be released as
"the" Pocket Commodore plus/4. For an almost full list of features and
preview screenshots, visit clickgamer.com/plus4
now. The release is due shortly, so if you like Yape and the Commodore
plus/4 and you're owner of a Pocket PC, this program is definitely
recommended!

| New Yape release |
12/03/2006

Yape 0.65 is out, with a
handful of new features and a usual bunch of bugfixes. A long requested
feature, symbolic keymapping, has also been added this time. It
basically allows you to map the emulated plus/4 keyboard to your own
PC's keyboard layout disregarding whichever input locale you are using
(well at least I hope so :-) ). Here's a full lowdown of what's been
changed this time:
- disk write support for 1581 emulation
- optional symbolic keymapping
- save screenshots as GIF (now default)
- fixed a sync problem on dual core AMD based machines
- fixed a glitch in decimal mode of ARR (thanks to
V.Lidovski)
- fixed a memory corruption when loading a D64 as PRG
(an abuse)
- some additional bugfixes
To activate symbolic keymapping, go to: Input setup->Input method
and select 'Symbolic keymap'.

page.

resurrected! |

Yape 0.63 brings you an
awesome new feature, again never seen before in any other Commodore 264
family emulator: the never born machine,
the Commodore V364 prototype, got emulated this time. Check out my summary about the way of using
speech on it. With this all members of the CBM 264 family are now
supported by Yape in both PAL and NTSC setups. The main changes in
this release are:
- Commodore V364 prototype support (Windows XP or MS Speech API
5.1 required)
- processor level Commodore 1581 disk drive emulation
(WD1772, CIA)
- D81 disk image format support (read only)
- emulate a TED glitch in graphic mode
- fixed a regression bug when saving tapes to WAV format
- a couple of bugfixes
If you are not running Yape under Windows XP, you may have to download
and install the MS Speech API separately. It is available as a free
download at Microsoft's website here. The
D81 support is read only for now and you'll only be able to use drive 8
for the 1581 emulation. Grab the new release from this place and have fun with it! On a related
note, Yape is celebrating the 5 years anniversary of its first public
release within a few weeks. It has come a long way since September 13,
2000 but it is so great to see it being a rather decent plus/4 emulator
;-)

| Yep! A new release
at last! |
10/3/2005

 New year, new releases :-) After a short
hiatus, here's a new Yape for ya. Packed with lots of bugfixes and some
cool new features, such as better TED emulation
and more robust user interface. Here is the list of changes:
- switching to full screen when VDU emulation is on,
works now differently
- play in background option in sound settings
- sound keeps on playin when emulator window is set to
'Always on top'
- easter egg: press Ctrl+Alt+X to activate the 1541
turbo loader hack
- more robust DirectX modes
- very obscure interrupt bug fixed
- various TED fixes
- lots of bugfixes
The undocumented key combo (Ctrl+Alt+X) activates a workaround, that
makes it now possible to load demo's that utilized the so-called Coby loader 8.0, a Megaload
derivant. These demo's include: Cracker's Demo 3
(check the screenshot to the right), No Silence and High Technology.
This - to the best of my knowledge - is actually the last piece of
loader that so far refused to load in the emulator and this hack -
while not solving the core of the problem - will circumvent a necessary
half cycle accuracy for now.
Head on over to the download page
for your copy.
