This game has a prerelease article
Tetris: The Grand Master, also known as TGM1 or simply TGM, is a Tetris game developed solely for the Sony ZN-2 arcade system board by Arika. It follows on from Sega's 1988 Tetris, aiming to give expert players a new challenge. It spawned three sequels, Tetris: The Absolute: The Grand Master 2 PLUS, Tetris: The Grand Master 3 - Terror Instinct, and Tetris: The Grand Master ACE.

This game uses the PlayStation based Sony ZN-2 arcade system board, so the ROM has several copyright strings from Sony.

This one isn't, though. This is for the sound driver.
The following text was found among the text for the Test Mode.

Some sound-related text that, ironically, is more detailed than the actual sound test included in the final game.

Looks like an interface for a Flash ROM writer.
Note: This game stores each line of text in reverse order in the ROM, so bottom lines of text appear earlier and top lines appear later in ROM. For the sake of readabilty, some of the unused text has been reordered.

This game was released only in Japan, so these warning texts weren't used. Texts for USA and Hispanic are complete, but others are cutoff and these were probably intended to reuse other warning texts for the rest.

Some Japanese place names. These were possibly where location tests were done.
How to play
The Tetraminos are moved horizontally by the lever. [The Tetraminos are] rotated by the buttons. You can drop the blocks quickly by putting the lever down. When an entire horizontal line is filled with blocks, the line clears from the screen. If the stack of the blocks reaches the top, the game is over ! There is some time before the Tetramino becomes fixed. The Tetramino can be rotated before it [becomes fixed.] Hold the button to rotate the Tetramino before it starts falling. If you can rotate properly before the Tetramino becomes fixed, then it is possible to put it in a tight spot. To fill tight spots, use the combination of the lever and rotation buttons.
This game was only released in Japan, but there's English tutorial text in the ROM. Note that some lines are reused but the ROM contains only one instance of them. These lines are marked with  in the above dump.
The game contains a number of unused backgrounds, suggesting that the game used an electron microscopy theme at some point:
There is also a 3D rendered Japanese style building:
Winners Don't Use Drugs
There is an unused "Winners Don't Use Drugs" graphic, presumably to be used in attract mode, further hinting at a planned US release:
