Best way to bob deinterlace 8bit pixelated footage mixed with live action

[LaserBones]

What would be the best way to bob deinterlace this DVD that has 8bit pixelated game footage mixed with live action footage? I've been using QTGMC with the setting below but the game footage loses a lot of it's crisp pixelation.

QTGMC(TR0=2, TR1=2, TR2=1, Rep0=1, Rep1=0, Rep2=4, DCT=5, ThSCD1=300, ThSCD2=110, SourceMatch=3, Lossless=2, Sharpness=0.1, Sbb=0, MatchPreset="slow", NoiseProcess=2, GrainRestore=0.0, NoiseRestore=0.4, NoisePreset="slow", StabilizeNoise=false, NoiseTR=0, NoiseDeint="bob")

Try is to lowering "ThSCD1=300, ThSCD2=110," to maybe ThSCD1=200 (or lower).
(side note: I would also add some deflickering)

1.: QTGMC(Input=clip, Preset="Fast", InputType=0, TFF=False, TR2=0, SourceMatch=0, Lossless=0, TR0=2, TR1=2, Rep0=1, Rep1=0, Rep2=4, DCT=5, ThSCD1=200, ThSCD2=120, Sbb=0, NoiseProcess=2, GrainRestore=0.0, NoiseDeint="bob") + deflickering
2.: QTGMC(as 1.) but with EdiExt using DDD (Vapoursynth only https://github.com/pifroggi/vs_deepdeinterlace)

Ps.: Maybe also try bwdif instead of QTGMC.
PPs.: Applying CAS + SSIQ (for the rainbows) might also help with perceived 'crispyness' .
