Unable to dump Tengen Tetris for the NES

[retrovik]

It finds it in the database but only creates a 1kb file after reading the cart. I have verified I can dump this cart with another device and it gives the correct crc and size.

Update:

If I manually set the mapper and PRG/CHR it will product a correct dump.

Could you take a pic of the PCB by chance?

[retrovik]

Unfortunately, the center back screw is under the label, and I do not want to damage this cart (because of the rarity). Otherwise, I would be happy to open it.

[Ancyker]

Fair enough. It does appear 3 should be the correct mapper anyway.

@nsx0r yeah?
