Summary 09197: All Tarzan and Starzan set: The graphics show characters crammed onto the screen
Description After several rounds, when pressing the Take key, several characters begin to multiply on the game screen, completely polluting the screen.
Steps To Reproduce Just put credits in and play at max bet until the problem occurs. It usually occurs when you press the Take button, and at max bet, I have the impression that you get to the problem more quickly.

Did this happen in older versions, too, or only starting with 0.278?

. Yes, it happened in previous versions. To reproduce the problem you need to play for some time, it seems that playing with a completely full total bet makes the problem appear more quickly. After the trash appears on the screen, if you change the layout, whether to OddsTable, configuration... when you return to the main layout the trash disappears, but reappears again in the next plays.

I had this happen with tarzan months ago when I was mucking around fixing inputs.

The game is switching between different areas of the sprite ROM, waiting for each one to be descrambled separately.

But MAME only calls tarzan_decrypt_sprites() once, at boot.

Maybe the solution is to detect when the sprite pool changes (probably by some write to protected registers) and call it again. This is just an opinion that may not be well founded.
