Blargg's SNES Composite filter & pseudo hi-res incompatibility

[DukeSkinny]

It seems the current core does not want to play nice with games such as Kirby's Dream Land 3 & The Great Battle IV which use the pseudo hi-res mode when the Blargg Composite filter (and others?) is enabled.

The horizontal stretch is due to running a super resolution on my CRT. Needless to say, they look fine if I remove the filter.

Core options, though disabling/enabling them all had no effect:

bsnes_aspect_ratio = "Auto"
bsnes_blur_emulation = "OFF"
bsnes_coprocessor_delayed_sync = "ON"
bsnes_coprocessor_prefer_hle = "ON"
bsnes_cpu_fastmath = "OFF"
bsnes_cpu_overclock = "100"
bsnes_dsp_cubic = "ON"
bsnes_dsp_echo_shadow = "OFF"
bsnes_dsp_fast = "ON"
bsnes_entropy = "Low"
bsnes_hotfixes = "ON"
bsnes_mode7_mosaic = "ON"
bsnes_mode7_perspective = "ON"
bsnes_mode7_scale = "4x"
bsnes_mode7_supersample = "ON"
bsnes_ppu_deinterlace = "ON"
bsnes_ppu_fast = "ON"
bsnes_ppu_no_sprite_limit = "OFF"
bsnes_ppu_no_vram_blocking = "OFF"
bsnes_ppu_show_overscan = "ON"
bsnes_run_ahead_frames = "OFF"
bsnes_sa1_overclock = "100"
bsnes_sfx_overclock = "100"
bsnes_sgb_bios = "SGB2.sfc"

I ended up using the tvout tweaks shader which works fine but it would be really nice to have a built in blargg filter in the core like mesen or that Sega core have. I've gotten better results with my shaders when I don't also have to throw in an ntsc shader
