Hello, I've just accidentaly found some web page. Here it is: http://gavin.panicus.org/doc/PAL%20NTSC%20differences.txt It deals with how to properly emulate PAL editions of NES games. I thought it may be usefull to people on ZSNES, so I'm dumping it here. Don't reply on this, because I won't be wat...

If I must use either vsync or tripple buffering to eliminate screen tearing, why should I then pursue double refresh rate of the SNES framerate? In other words, what benefit do I have when setting screen refresh rate to "round" value of 120Hz (=60FPS x 2) when playing NTSC games, instead o...

One more thing about refresh rates, screen tearing, VSync and its slowdown. I do not completely understand all about that issue, but I have a straight question. Blackmyst asked me if I have good monitor. Yes, I have IBM G78 - 17" flat Shadow Mask CRT with 85kHz horizontal refresh rate. That mon...

OK, I spent some time yesterday trying to tweak ZSNES on this machine. First I have made a compact bootable DOS disk. No EMM386. The Fastvid patch was applied (anybody remembers this?) to enable PCI bus features, which are unfortunately turned off on all PPro chipsets. This solves the huge bottlenec...

I apologize for being absent. I am rather busy these days. I am going to write a proper reply, but not today, I am afraid. Hopefully tomorrow.

As far as I know, they're pretty much rewriting the ZSNES core and doing a code audit to get rid of all the trash that's been piling up over the last several years. This sounds to me like ZSNES has really got slower and slower during the last couple of years. And to be honest, that is the impresson...

PAL vs. NTSC ROMs - in terms of speed

Hello to everyone. This is the first time I have decided to write here. I am not new to the emulation scene, but I have been out of the wagon for a couple of years. But I have played games on some fetus ZSNES versions some five years ago on my Pentium 166MMX :) To get to the point, I have assembled ...
