Summary 09193: jking200pr and all starzan dependents: Graphical or security error causes the appearance of a character that does not exist in the original game
Description When exiting the game and returning, when placing credits in place of Tarzan, several pink whales are shown. It seems that the problem occurs when the nvram receives some writing and activates the error or security, causing the failure.
Steps To Reproduce Turn on the game, the first time it will say "System reset" (probably due to lack of DIP mapping), exit the game and when you return insert credit and the whales will be shown. Sometimes after a few rounds, the screen randomly fills with characters from the game polluting the entire screen.

I can confirm that the pink whales show when a credit is first inserted.

However, I cannot say if this is an issue or not.

Unable to get the screen to fill up with unwanted characters.

When testing, note that the Z key does both BET and STOP (unless you turned on auto-stop).

In version 0.277 the whales were not appearing, the problem probably started when implementing nvram saving using the shared Map from "iqblocka". Maybe starzan needs his own map, the nvram also seems to be smaller than it should be.

not saving the full nvram properly would certainly cause such issues

That's exactly the problem, the nvram is not complete, the first part is completely empty and the file is only 4kb, when in fact it should be 32kb. The iqblocka mapping only works partially for the starzan set

Setting double the amount of NVRAM seems to fix the issue. I'll commit later today but please leave the bug open until the OP or someone else who knows how to play these games test them a bit more.

Same problem also affects the sets based on the tarzan machine config.
