If you can find out how to allow the Mr. TomatoS game to guarantee the "fatal error has occured." thing through a setting for the next update, I'd be greatful.

Sorry but that "fatal error has occured" is random. The probability of this happening is 1/150. There aren't any non-virus-behaving ways of modifying the values in the memory.

Each program runs in a separate memory block, which means that I am not able to force this to happen by running another modified "MrTomatoS" or a Mod.

The only possible way is to modify the value during the game program is running; however, it is virus-behaving and I do not have the strategy .

Sorry again for your waiting.
