Could you use a better Scaler for this Emu? Or different Modes like nativ, scaled, scaled-enhanced...aso.

ScummVM has good scalers and opensource.

Thanks for this Spiller, you know my uncle had the original Lynx handheld along a with a GameBoy, and he was glad that the Dingoo can emulate the Lynx, because it was his fave handheld along with the GameBoy.

+1 for you.

I spent half an hour or so playing Shanghai (great game) last night.  It plays almost perfectly! 
Occasionally (like once every 3 or 4 mins) I see a split second of screen flickering - it's barely noticeable. 
And the music plays too fast, so I hit a button (OPT 2?) to turn the optional background music off.

I saw one comment that they found the emulator runs too slow, but my observation is that with Shanghai, Ms Pacman, and a couple of others it runs about 10-15% too fast!  It's really noticeable in the background music of these games.

Although I have no actual experience with the Lynx, I think the emulator runs too fast too. As said, I will be looking into the timing but it may take a couple of days to find a solution.

About the scaler: the native resolution of the Lynx is 160x102. I'm simply doubling the number of pixels to 320x204 right now and I wonder why anyone would want something else. I don't think it's going to be prettier with a scaler.  Wink

Second beta:

http://www.speedyshare.com/163829299.html

Includes load/save state functionality and the ability to change the volume and emulator timing from the menu. Should be fairly complete functionality wise. Next up is fixing the timing which will hopefully end the graphical and sound glitches.

Simply doubling the number of pixels is not very nice. Interpolating is far more nicier and i think the speed is high enough to try something :-)

For example sai2: https://sourceforge.net/apps/trac/scummvm/browser/scummvm/trunk/graphics/scaler/2xsai.cpp

or they have lots of others:

Links don't work for me, require Password.

If you want to get closer to the look of the real Lynx, just leave every 2nd pixel blank, the LCD Pixels on the original Lynx where not very close to each other, I think this was a technical decision to achieve a larger display. I am not complelely sure if this was only between the lines of between each pixel in the line as well, I just discovered my old Lynx doesn't seem to work any more.

Everyone's a critic...

Hey spiller, I think the simple doubling of the screen looks just fine.  I agree with you that with just 36 extra rows of pixels to play with, there isn't a lot of room for improvement.  I think other issues such as speed or sound are much more important.

Maybe I will look at the scaler at a later time, but the timing issues are more important now. Toki is my game of choice now for experimenting. It even includes a countdown in seconds which is clearly going too fast currently.  Smiley

Oh maybe you need a sourceforge account, i forgot.

of couse timing is more important right now. it was only a suggestion, because i was playing around with this scalers for my pie port.

You played with an anti aliasing scaler in PIE SiENcE, was it fast   ?

Spiller, i've tested a little your new version. It's not really easy to know with cycles are accurate ...
Execpt this pb, it works fine, i've tested Xenophobe, Rampage and they work fine.
Just one pb, i think there is a colour pb in Roadblasters, certainly a cycles pb too.
