This version is basically a bugfix release. It solves a couple of serious problems (and still leaves a lot more untouched) like the now infamous fullscreen crash... Sorry about being so late (read: lazy) with it. In next releases I'll continue focusing on code improvements, mainly the parallel port IEC emulation which is rather buggy at the moment while at the same time isn't very functional either. But let's see what has been fixed in this release:
fixed a crash on some machines in full-screen mode
fixed a bug in handling sound channels
fixed a bug with the speed indicator (no more 105% I hope...)
fixed a bug concerning emulator ID set in the ini file
menubar is gone from the fullscreen mode until it'll work properly
There's another known problem with the tape emulation (saving to MTAP format), which either will or will not work depending on your luck as a few folks reported :-) I'll have to look at that later... Another important announcement: in case you're the proud owner of an NVidia card (like me :-) ) I'd definitely recommend upgrading to the latest Detonator drivers (41.09) as it'll improve performance in doubled screen mode enormously under NT. You can get your copy of YAPE here!

5/9/2002
A new version is now out with improved NT/2000/XP compatibility and much better digi sound support. The changes in this release in details are:
started implementing a status bar
limited speed does not use up 100% CPU anymore
improved TED DMA timings
largely improved digi sound support
digi sound now works on NT/2000/XP
forced full speed now mutes sound
optimised sound emulation
optimised screen rendering a bit
fixed file association bug on NT/2000/XP
fixed fallback sound mode
fixed wraparound of two zero-lap opcodes
Thanks to all those people, who helped me testing the beta releases, you know who you are! Grab your download from here!
Release 0.40 of Yape is here
3/8/2002
This is basically a bugfix release, a couple of people wrote in to let me know some crashes, so here's a lowdown on what's been amended:
enhanced the internal monitor with some more editing functionality
tweaked a little on the timers, they seem to behave better now
fixed a sound initialisation bug
fixed a glitch when writing to the raster line registers
fixed a bug with pending IRQs
fixed a potential crash in the keyboard handler
fixed a crash with very long path names (it'd only crash now if they're very-very long :-) )
Cheers to Csabo for his help improving the monitor. Download your copy from here!
Yape 0.39 is out
31/5/2002
Here's a new release before I mess up the whole source code once again for no good =) Again, let's see what's new:
ZIP file support
optimised TED screen rendering a bit
slightly optimised main loop
fixed some glitches with the horizontal scroll
fixed the IRQ when it occurs right after masking it
fixed a bug when reading ROM area above $FF20
ZIP file support is pretty straightforward, it'll always try to open the first file in the ZIP file. One might also note that this is the fastest performing release ever (don't hold your breathe though). Get your download from here!
Version 0.38 of Yape released
16/4/2002
This release brings you emulator identification, which is located at address $FF58, and I'll throw a small note on the site soon on how to detect it. Basically, it's similar to the way VICE works. Furthermore, here's the what's new list:
optional emulator ID at ROM address $FF58
selectable screen update frequency (aka frame skip)
second fire button on a PC joystick now swaps between port 1 and 2
third fire button on a PC josytick will toggle autofire on/off
window position is now saved and restored from the INI file
some optimizations in the CPU emulation
some bugs in the TED emulation fixed (mainly raster)
Another month, another release. I've been working on the edge these weeks. A major thank you goes to Csabo this time who relentlessly pointed out a whole bunch of bugs to me, some of those are still left as pending. But let's see what's new:
character bank reload implemented (no bitmap for now)
keyboard shortcut for switching to maximum speed (ALT+W)
limited frame update frequency for sake of fast machines (max. 85 fps)
TED sound is not lost anymore when switching to full screen mode
CPU jam will now pop up a message box
changed the IRQ sequence a bit
fixed a huge bug when switching between fast and slow mode
two existing illegal opcodes fixed
fixed cycle timing of a few opcodes
fixed a couple of bugs in the external monitor
fixed the screenshot routine (got a bit broken in last version)
some annoying keyboard bugs fixed
I expect that most of the timer based protectors should work now (in games like Barbarian 3, Robomutant, StarWars etc.), if not, please give me a note. There was a stupid bug when switching between the fast-slow modes that prevented the emulation to realise it in due time, so that sometimes it came only after a 6 raster line delay (ooops...).
Please don't expect the 1541 emulation to be very accurate for now, as I am still having timing problems, and have to implement the ability to debug the drive CPU in the external monitor... Though a couple of disk based games and programs should work now (such as the Zork series, for example). Also note, that since the 1541 drive is apparently having yet another CPU, it'll slow down the emulation considerably. Grab your download from here!
Yape 0.36 is here with Love :-)
14/2/2002
Valentine's Day brings us a new version again with a couple of new features and the usual fixes:
modified keyboard layout, see Readme.txt for more
SHIFT LOCK and joystick autofire implemented (on CAPS LOCK key)
vertical and horizontal blank implemented (default screen got smaller)
a new full screen mode by default (400x300)
window area delaying implemented (only in text mode)
fixed some more IRQ problems
fixed a memory address overflow bug
you can now associate plus/4 program files with Yape, and then run your games
by simply doubleclicking on them
uses log window instead of log file (yapelog.txt is gone for good)
As usual, you can find the new version on the download page. On a
side note : Tom will work now even better now than ever before, especially with the new SHIFT
LOCK option switched on. Have fun!
Yape 0.35 is released!
3/2/2002
Here's a new release with some bugfixes, some new bugs and some nice new features:
ALT+ENTER now always works
added saturation to the video settings
new sound settings dialog window
copy emulator text screen to the clipboard
fixed the SID card emulation a bit
fixed a bug in save/load snapshot
fixed a bug in the ROM setup dialog window
fixed another IRQ problem
Go get it from the download page while it's fresh !
A very important new Yape version is ready (v0.34)!
29/1/2002
I've been spending again some more time working on the emulator lately, and the outcome has surprised even me ;-). One important feature has been added back to Yape, and another longstanding bug has been corrected, that made plenty of games working much much better that have so far been buggy, such as Tom, Star Events, Gullwing Falcon, to name just a few... But let's see what's new:
SID card support is back and is now better (though not really accurately timed)
largely improved original palette (fixed saturation, not so greyish anymore)
fixed two awkward, long standing bugs in the IRQ handling
This is not much you might think, but it's definitely worth the download, as will give better quality of emulation for some games. Fetch your copy here! One important note is that you can't use TED and SID sound together, but that's obviously isn't really necessary anyway.
New Yape version is out (v0.33)!
21/1/2002
Yep! After a long-long while... It took me almost one year to kick out this "next" release of Yape, but at least I made it :) In case you expect huge updates, I have to cool you down, as this release is rather about me getting back on track... Anyway, let's see what's new:
added display contrast, brightness and gamma correction
one missing key added (oops)
numeric keyboard now always acts as cursor keys, even when joystick emulation is on
reworked INI file a bit
window always on top option
the original palette is now the default
As I'd been playing with the emulator again, I had to realise what a big mess the source code is... A major rewrite is necessary anyway for several reasons (true drive emulation, TED accuracy, etc.), but that'll be a painful process :P In the meantime, get your download here! Don't forget the YAPE forum, where you can post your thoughts about Yape, after you've registered yourself (which is easy).
Yape forum on KiR opened!
