Is the sound emulation more precise?

I used to think that VICE was extremely accurate with sound but recently I've realized that on some games at least, the sound emulation falls really short.

when using the new PAL mode along with double scan it tells me there is a "drop in performance" and suggests to revert to the old PAL mode

As regards the screen aspect, I once wrote to VICE-team asking to put a special double size mode for vic-20 with different pixel square, but they did not even reply to my message.

I also tried to add that feature by myself modifying the VICE code, but it was an hell, and all I've managed to get was a 1x1 pixel square VIC-20 emulation (I still have the executable somewhere).

I'm curious about the result... Is the exe working correctly? If so, why don't you upload it somewhere?

The GIMP helps us figure out the resulting screen:

yes this is the result. We talked about that some time ago on this thread, see the bottom message on first page...

I use full screen 848x480, and the look is perfect with the correct proportions in screen. (in Windows XP 1024x768 screen)

The problem is only in windowed screen

I just spotted a very odd bug that has been present since 1.22 or older:
POKE 36874,255 = POKE 36875,255 !!!

However POKE 36876,255 generates a different note.

I'll see if I can fix this one and send a bug report to the VICE team. While completely reworking the sound is a biggie, this one should be easier to fix.
