Sorry for the delay, Thanks for your answer.

Texture problem is due to Roms Board eeprom (not yet identified).
Second problem is due to CPU board (IC60 or one of the two OPR) AND Video Board.

I buy 2 complete Model2 Daytona Boards to repair.
But I have problem with Rom Board. A blue screen appear when I use it. In the SEGA manual, blue screen is due of wrong plug of boards.

Any idea?

Thanks
