Do you know if Paul ever looked into the Baseball issue on his emulator?
I think he's busy on the next Retrochallenge, but I bet he fixes it eventually. And now that all the carts are dumped, he can add support for the new ones at the same time.
I haven't installed the development environment he uses, but I hex-edited his exe to run the new carts: www.seanriddle.com/mvem.zip
I had to create 4 exes to run all the carts. Read the readme.txt for details.
I found an extra 1-bit in Pinball; the file in mvem.zip is the corrected one.
He had different paddle timing in Pinball, so I used that for Baseball, and now you can swing, but I always get out. Maybe there's still a bad bit?
I updated the file with the raw dumps and the pics of the ROMs: www.seanriddle.com/mvraw.zip
