Where is the original GB font?

I would like to use the font that's used in Tetris and Super Mario Land in my game but I can't find it anywhere. It's not the "IBM font", you can see the I in the Tetris font has the serifs while the "IBM font" doesn't. Is there some way I can use the original font, which seems like it should be the default font but isn't?

You could just rip it. In BGB: Start for example Tetris and look up where in tile memory it loads the font using the VRAM viewer. Then choose file, save memory dump in the debugger. Then enter 8000 as the start address and 270 as the length. There are also a couple more characters starting at 89B0, namely quote mark, comma and combined period+quote mark.

I did that and I got a .dump file. How do I use it?

I did it! What I did was saved the alphabet data in asm and then stuck it in the game's code so it displays correctly.
