Unofficial 1.41 - by Keith Kelly


This is an unofficial maintenance   release I created to fix an annoying joystick lag issue.

This lag was particularly bad when   VSync was enabled. The original   Nestopia author (Martin

Freij) appears to have abandoned the   official Nestopia project on SourceForge and has not

responded to any of my e-mails, so I   am left with no choice but to provide this unofficial

release as a public service to the   emulation community.


1. Removed manual option to set   priority of Nestopia's main emulation loop thread. Instead,

Nestopia now boosts its own process   base priority AND its own main emulation thread priority

whenever it is the active foreground   window (and/or running in full-screen mode). This brings

Nestopia much closer to real-time   performance and responsiveness.

2. Removed some screwy input polling   logic, and added some calls to input.Poll(), to ensure

that the input devices are always   polled immediately before the input state is utilized.

This was the key change that got rid   of most of the lag.

3. Removed some screwy input timing   logic that was causing input polling to work only on

certain clock intervals, rather than   allowing it to work every time it was called.

(As far as I can tell on my own   hardware configuration, these three changes taken together

have completely eliminated the lag   problems that have been present in Nestopia for several

releases. Your mileage may vary.)

4. Updated the Visual Studio   solution/project to build successfully under Visual C++ 2008

Express Edition.

5. Added this releasenotes.txt file   and bumped the version number to 1.41.

Given the fact that it has taken   almost two years to complete this release

I've basically lost track of the   shitload of changes and fixes I've made

throughout this time, but I'll try to   cover the most notable new additions.

But first, I'd like to thank all the   beta testers who helped shaping up

this release, especially Hellsbane,   Michael Walsemann, Benjamin Siskoo

and Robert Tuccitto for their   dedicated time and effort in searching for


The Windows port has been rewritten   from scratch (which proved to be more

-Cleaned up a few thing in the GUI.




-Added UNIF support.

-Fixed a bug in the Game Genie   decoder, now eight-character codes works correctly.

-Added support for more axis buttons   (sliders, pov etc). Havn't tested them tough as I don't have that kind of

joystick, can anyone confirm they work?

-Fixed so that Nestopia will   recognise the Twin Famicom BIOS ROM.

-Added adjustable dipswitches for   "Nintendo World Championship" (mapper 105), now you can control and   display the timer.

-Fixed mapper 91 (IRQ counter thing),   now all mapper 91 games shows the correct graphic.

-Fixed mapper 187, now "Street   Fighter Zero 2 '97" works.

-Fixed a bug in the Sunsoft FME-07   sound core.

-Did some cleanup in the application   error handling routines - no more page-faults on known errors.

-No more distortion in screen when   enabling/disabling the menu in fullscreen mode (LockWindowUpdate() to the   rescue).

-Fixed a bug which sometimes caused   the window, when coming out of fullscreen, to be maximized and stretched to   the size of the desktop.

-Fixed a bug that caused the   switching from window to fullscreen with the same display mode to fail.

-Fixed a bug in the PDXSTRING class,   nothing that affected previous versions of Nestopia though.

-Lowered the system requirements to   Pentium MMX, users with processors that lacks the CMOV instruction can now   run Nestopia.

-Added some menu options to control   the size of the window/screen (works both in window and fullscreen mode).




Fixed a bug that caused the   application to exit with the "DirectSoundCreate8() failed" message.
