8e0816807f Add sprite frame range condition 
A new condition named "spriteFrameRange" is added. It works like frameRange except it follows frame counters assigned to each sprite. Frame counter picks up the nearest frame counter within 6x6 pixels from the last frame and resets if graphics, palette, bg priority or orientation has changed. The condition can by used by sprite tiles only. For example:

<condition>myCondition,spriteFrameRange,301,60
[myCondition]<tile>0,1001,FF0F3600,8,0,1,N

dbe7e0dec8 PPU: Moved oam row corruption region by a couple of dots, to match oam_flicker_test

77b4289299 PPU: Tweaked sprite evaluation code to simulate another hardware glitch seen in the oam_flicker_test_reenable test 
When rendering is enabled/disabled around scanlines 128-136, a single 8 pixel sliver of a sprite appears on the following scanline, due to the previously discovered bug where disabling rendering increments the oam address pointer by 1

f7ff089689 Core: Fix NMI code to better reflect the hardware 
Fixes a crash in Super Chinese 3 caused by the PPU rapidly switching the NMI signal on and then back off (which caused the CPU to incorrectly jump to the IRQ handler and crashed the game)
