The other day I got this Twin Cobra 2 F3 cart in the post. It has some minor corruption to the title screen and during the bomb explosion but otherwise plays perfectly. It's not at all obtrusive and means I got it cheap. It's credited to Takumi but a lot of the programming was actually done inside Toaplan before they folded. A lot of staff who were working on it then finished it off under the Takumi name.
I also got Mahjong Kyuretsuden. That's 120 / 148 MVS games.
