I had several people at my house this evening, and a couple of people were playing Raiden DX on my JAMMA cabinet, credit-feeding their way through Alpha mission in 2 player mode. After this was completed, I started them on Bravo mode, and a few minutes later they returned to the other room, so I had assumed the game had ended. When I checked the cabinet, the game was still going, so I started playing it and soon found out that for some reason player 1 seemed to have inifinite lives, and I was able to play all the way through the end of Bravo Mission without continuing. It seems to me that I might have seen similar behavior before after a 2-player game, but I don't recall the specifics. I'm wondering if anyone else might have seen this happen before, or if it happens to be a known glitch?
The board is the Asian (Metrotainment) version, and does experience a few graphics glitches when first started, but these go away shortly and the game appears normal after that. Other than being on free play, the DIP switch settings should be the defaults..
