Family BASIC and AV Super Real Pachinko should be fixed with the updated Developer Build. The rest, I don't know about. What Build are you testing these ROMs with?

Latest stable build.

My goodness there always seems to be more NES games 0_0

I'll scratch games off the list as I fix them.

Chuugoku Taitei (Asia) (Unl) - Black Screen
Hard Drivin' (USA) (Proto) (Unl)
Bugs Bunny Birthday Bash (USA) (Beta) [b]
Dr. Mario (USA) (Beta) (Between 1990-02-02 & 1990-04-27, later) - Crashes Bizhawk

Metal Fighter (Asia) (Sachen) (Unl) works fine for me.
Same with BB Car.
What issue are you having with them?

BB Car really has no problem, my bad. But Metal Fighter has. Look the screenshots.

Ah, ok you need to make sure you use NESHawk.
Look at the bottom center of the window in your images and you will see 'QuickNES.'
This is the less accurate and less compatible (but for some reason the default) core.
To change cores, load a ROM, then go to NES->Core->NESHawk.
Then Go to Emulation-> Reboot Core.
Now you will see NESHawk instead of QuickNes at the bottom of the screen.
Metal Fighter will then play correctly.
Please make sure the games on your list are actually NESHawk, as QuickNES is not actively maintained.

Sorry, but it happens with Neshawk too.

That's weird, maybe you have a different ROM, can you click on that little question block in the lower left of the screen and copy paste the info in it?

This is a No-Intro rom.

Same ROM, What version of BizHawk are you using? The game loads and runs correctly in the latest release 1.12.2

This is what I get:
