I just did not even know this Tatung Einstein version existed. I have written a brief article on Einstein Manic Miner:
Feel free to copy anything you wish to this site. I am not sure if it is interesting, but I would recommend getting the ZIP that contains 20 different disk images. Like I say in the article, I could not find a ML Monitor feature in MAME, so I wrote two simple C programs to create separate disk images for each room. This means that you can now start the Tatung Einstein Manic Miner in any room you wish! It is a bit clumsy to have to load a different image, but it works.
I actually tried The Final Barrier and to my surprise this version has a proper ending! Miner Willy ascends up to the ground and the game ends!
