V9938 emulation progress
I finally got the V9938 instruction 0x0F working (high speed put bytes CPU->VRAM) and the instruction 0x0E (high speed Copy Vertically), which made Gryzor/Contra playable, fixed some missing graphics in Vampire Killer (most notably the doors at the end of the levels) and made various other games work somewhat better.
