And "Champion Boat" needs the normal VT03 palette. So there must be a switch between the normal VT03 hue/luma/saturation 4-4-4 and R-G-B 4-4-4 palette.
Edit: the only thing in terms of register writes is $411E. Value $05 has two bits set, so maybe one of them turns on encryption after the next jump, while the other switches 12-bit palette types?
Edit2: No, that doesn't work for Thunder Man either.

FC Pocket 600's palette is just four bits each of blue-green-red. Now for the PCM menu music...

All you needed to do was change the Mirroring bit in the NES header from Vertical to Horizontal. It's quite a common problem with many ROM images from the internet. NES Cart Database is a good source for information on what the NES header should look like for any particular game.

You add 16 bytes at the top using a hex editor, change the first four bytes to "NES" and 0x1A, and then open the file using Nestopia's or Nintendulator's NES Header Editor, select a NES 2.0 header, set mapper to 256, and the number of PRG banks to the ROM size in Kilobytes divided by 16.

Nintendulator-NRS runs TV Game 200-in-1, as does CaH4e3's current FCEUX build from his website.

@forgotusername: I can offer to extract all of the individual games, as I did before.

Now it does. Changed from checking whether $4304 bit 0 is 1 to whether any bit of $4304 is 1. Note that I am in the midst of updating the input code, so you will have to set your controller input assignments anew when using this build.

Is the menu supposed to be this, uh, empty-looking?

Is the chip really a VT03? Because all the games on it seem to use VT02 features only.

I am providing my current WIP build so I can post a few dumps that were previously unemulated.

Just to be sure I am not getting things wrong: is "Fire Fighter" (game #118) really just a wacky name for a Super Contra variation?
