Display unused Japanese Tetris DX title screen text in CGB mode. (Palettes do not exist however, the Japanese boxart and cartridge label show that it uses the same palette as the Tetris DX backdrop. It is unknown why this was changed or not used. The Japanese version of the game is the same as the US version. NOTE: Turn the code off after loading the title screen otherwise the square waves will sound monotonous. This is because the Game Genie codes conflict with the sound driver and inadvertently shares the same values 01 and 02. you only need to turn the code on as the title screen loads, so the effect is minimal without patching the the values directly into the bank mitigating the issue. The first code will allow the screen to transition and the first set will fix the palette issues and the rest will set the tiles.) 220-31A-199 030-34A-E6E 030-32A-E62 030-30A-E6E 030-2FA-E62 030-2CA-E6E 030-20A-E6E 030-21A-E6E 030-23A-E62 020-25A-E6E 030-36A-E62 030-37A-E62 030-3AA-E62 030-3BA-E62 030-33A-E62 030-38A-E6E 030-39A-E6E 030-31A-E6E 030-35A-E6E 030-2EA-E62 030-2DA-E6E 3EE-B1B-80F 1EE-B0B-80B 3EE-AFB-80F 1EE-AEB-80B 1DE-ADB-80F 1CE-ACB-80B 1BE-ABB-80F 1AE-AAB-80B 17E-A9B-80F 16E-A8B-80B 15E-A7B-80F 14E-A6B-80B 3EE-A5B-80F 12E-A4B-80B 11E-A3B-80F 10E-A2B-80B 0FE-9AB-80B 0EE-99B-80F 0DE-98B-80B 0CE-97B-80F 0BE-96B-80B 0AE-95B-80F 09E-94B-80B 08E-93B-80F 07E-92B-80B 06E-91B-80F 05E-90B-80B 04E-8FB-80F 03E-8EB-80B 02E-8DB-80F 01E-8CB-80B 00E-8BB-80F

Demos play for a really long time. So, they actually did record more of the in-game demos, and they just gave up after clearing a Tetris which is really hilarious. All of the demos are actually predetermined and do not give random pieces. After the eventual game over, the game shows a glitched menu. Huh, that's interesting. FF1-B6E-F76

Title screen demo sequences play forever (Fish tank, Nintendo Game Boy Now in Color, Triangles with and without the Nintendo logo will play forever as well as the in-game modes, which will eventually game over and cause glitches including menus, title music playing in-game, etc; if this happens just in-game reset to clear the RAM.) 7E1-B4E-3B7 Title screen demo sequences play a really long time (So, they actually did record more of the in-game demos, and they just gave up after clearing a Tetris which is really hilarious.
