5daa1b6225 Video: Fixed/changed some aspect ratio calculations 
-Fixed calculation for width for NTSC/PAL
-NTSC/PAL are PAR, as before, but 4:3/16:9 are now DAR instead, since their purpose is to fill the user's screen, regardless of overscan settings

6539b92502 SA-1: Fixed timing regressions 
Memory handlers did not have the _memoryType value set, which caused some memory accesses to be much faster than expected

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)
