Blast Generator

The Blast Generator is a tool which acts similar to classic style ROM corruptors. You can use the Blast Generator to create blastunits.

Domain

Domain targeted by the line of action

Precision

Word size on which generated BlastUnits will operate

Type

Type of operation that will be appended to the units

Mode

The mode for generation

Interval

How many addresses to skip in between generated blastunits.

Start Address

The address to start corruption generation at

End Address

The address to end corruption generation at.

Param1

A parameter for the corruption generation. See below for details on how it's used.

Param2

A parameter for the corruption generation. See below for details on how it's used.

Endianess is always handled as little endian, or right -> left. This is completely agnostic of core endianess

That means that:

10 on 16-bit precision will be treated as 00 10

1000 on 16-bit precision will be treated as 10 00

Ranges are exclusive, meaning that the last address is excluded from the range.

This means that:

Start Address of 10, End address of 16, step size of 1 would generate blasts for addresses 10,11,12,13,14,15

Lifetime

For how many frames will the BlastUnit execute

Execute Frame

At which frame will the BlastUnit start executing

Seed

The seed will ensure that the generator gives consistent random results if reproduced later.
