Summary MESS-specific 06701: pce [shingen, shingen1]: Extended/Unexpected periods of Black Screen
Description The game, Takeda Shingen, no does not start properly. It instead has a long periods of black screen waiting before the title screen starts. Same type of extended black screen when you hit RUN button to start as well when introduction symbols scroll right to left on screen. There is no delay for earlier versions and I presume is that way on original hardware.

I noticed on my end If you wait about 25 - 30 seconds of black screen (can also fast foward), you're then able to press Run and start a game after seeing title screen.

Updated description to better suit. I did not run the game for over 20 seconds to see if there was some odd delay which appears there is now and can confirm the change in behavior from previous versions.

Culprit is VRAM-VRAM DMAs, it sets up multiple transfers with 1 byte length at POST.
Currently huc6270 does one DMA for each vblank (which is wrong, but I don't know the exact timing?).
