The latest version of the GPVSGB emulator is indeed an improvement, sound is now as good (or bad) as the original Game Boy, speed has also been increased.
However, in most gbc games, the speed is too fast! Zelda runs at 120% of the original speed (estimated, unless the screen is filled with monsters), Super Mario DX even faster. While faster is better than slower, some kind of automatic sync to always keep the speed at 100% of the original would indeed improve the situation.
The screen bug in for instance Zelda in which the scoreboard (the top of the screen with items/money/hearts etc) very often is swapped around with the bottom is still there.
Other than that, great progress!
