2a6504c2d4 PPU: Fixed mirroring behavior when vram address is over $7FFF 
Prevents graphical glitches in Lemmings 2 (which appeared because the game uses addresses over $7FFF, which loaded random data outside the vram buffer)

d32f512b7b NMI: Set CPU's nmi flag during irq/nmi flag update instead of right away 
Fixes a freeze at power on in Chou Aniki.
The game writes to 4200+4201 (16-bit write) to enable NMIs in the middle of vblank and expects the instruction after the write to run BEFORE the nmi handler is called (not doing so causes the game to freeze)
