WS Flash Masta v5.1

[-ffix]

Hello, this is my first message. Sorry for my English.

Tetris (Japan).wsc works, but in black and white, when the game is in color : -O   I have a WS Crystal without mod

Your English is great.  Don't apologize for that.

I think that the rest of us also don't understand the problem with Tetris.  This has been a known issue.

From Juhn's testing, I was under the impression that XI Little worked.

Tetris works in color if you start it using the start button instead of A.

This behavior is the same with the original Tetris cartridge — boot the WonderSwan Color while holding A and the game will be in black and white instead of color. WS Flash Masta is not doing anything really different from the physical cartridge, apart from using a different save mechanism (thankfully the patches help with that part for Tetris)

Edit: also, if you tap and release A very, very quickly the game will instead start in color!
