4065f9a45d GB: Fixed graphical glitches during start sequence in Densha de Go 2 
Unsure if the fix is correct, but this is what breaks the game's timings. Until the GB core's LCD timings are improved, this will do - this fix does not seem to change the result of any test rom

7c51e23d25 GB: Fixed envelopes being clocked when period is 0 
Based on Megaman 2 and Taiyou no Yuusha the envelopes shouldn't be ticking when period is set to 0 (otherwise the sound in these games breaks - especially the noise channel)
This seems to contradict old documentation that says a period of 0 is treated as a period of 8, but test roms don't seem to validate either behavior and this fixes the audio for both games.
