Thank you so much for the confirmation - this helps a lot. Really strange that Sachen couldn't even get their facts right. When this 31in1 is around I'm pretty sure also the 6in1 can be found somewhere.
The 31-in-1 Mighty Mix just got dumped by Tauwasser. Sorry to ask but finding those games is really a nightmare sometimes: Are you willing to lend Tauwasser your game for dumping purposes? Should be easy now unless they changed something for whatever reason. He appears to be very reliable and communication is easy (we are both at no-intro forums). If opening the cart is required: I have found a pretty good method to do so within seconds without causing damage in most cases (I have made a video but need to find the link again where I uploaded it). Most means the shells are a bit different and some are harder to open than others which means it could cause a small white mark in the plastic on the side (which appears when it's bent too much) but not more. In approx. 8 out of 10 cases there is no damage at all. And for the remaining cases I might be able to find an improved method.
We are also desperatly looking for both 16in1, the 6in1 mentioned above and the last single game release 2002 Gedou Zhanlue.
