TSP50c1x MB games test modes found so far (All games programmed by Michael Gray, I believe; I need to verify what games he programmed at some point, he has an account on BoardGameGeek): The test modes are all accesed by holding down a key and pressing the 'on' button:
Electronic Talking Battleship(1989): Key Test: Hold the Player 1 A1 key (or Player 2 J10 key which maps to same matrix position), then press the green 'On' button to enter key test mode. When in key test mode, you are expected to press player 1 keys A1, B2, C3, D4, E5, F6, G7, H8, I9, J10 in that order, the system will beep after each key is pressed. Then press Player 1 Fire, the system will say 'two'. Now press Player 2 A1, B2, C3, D4, E5, F6, G7, H8, I9, J10 in that order, the system will beep after each key is tested. Finally, press Player 2 Fire, the game will say 'Battleship' and play the explosion sound while flashing the ship explosion LED, then turn off.
Sound Test: Hold the Player 1 B2 key (or Player 2 I9 key which maps to same matrix position), then press the green 'On' button to enter sound test mode. The game will play the beep, all of the speech samples, the firing arc and music jingles in order, followed by the explosion sound and the flashing ship explosion LED, and then turn off.
Omega Virus(1992): Key test: Hold the '0' key, then press the 'On' button to enter key test mode. The game will say 'zero', 'one', 'two' when pressing the 3 number keys, and will say <monotone>'we are running out of time' when pressing the 'Repeat' key, and then turn off.
Sound test: Hold the '1' key, the press the 'On' button to enter sound test mode. The game will play the explosion sound followed by all of the speech sounds and sound effects, followed by the glitch samples, and then turn off.
I am assuming the international (german, spanish, italian, french, etc) versions of these games have the same test modes. (I also assume the test modes are the same on the 1998 ?re-release? of electronic talking battleship. It is quite unclear what changed between the 1989 and 1998 releases, but they use different mask tsp50cxx chips, so there must be some changes. Would be worth checking if the C3 key plus 'On' activates some new test mode that didn't exist in the older MCU)
Given the way these test modes work, I suspect dream phone and other games of this era probably have a similar set of tests if you hold the '0' or '1' keys on the phone or other entry pads while turning on the game.
Also note Omega Virus has a hidden game mode: After you press 'On', and the game asks you to enter skill, press 'repeat' 3 times and the virus will laugh once then taunt the players. This enables an extra difficult mode where the virus will start to move between rooms once any player gathers all 3 of the items needed to kill it! This makes the endgame MUCH harder!
P.S. If anyone has one of the international versions of these games, please open them up and send a picture or text of what is written on the tsp50cxx 16-pin mcu! The CSMxxxxx number will be different from the english ones. I'm curious if there is a British/UK voice version of some of these games as well.
