Update 2013/05/17: Initial public release
ROMIMG is a tool that handles IOP image files (e.g. those IOPRP images and the boot ROM image itself) that are used for IOP resets or for just storing files.
It has the following features:
Note: The RESET file entry cannot be detected because it must be there for the image to be considered valid. However, deleting it with the delete command will just clear off the bootstrap program. A bootstrap program can be added to an image that does not have one (RESET is 0 bytes in size).
The bootstrap program is a binary file with the entry point at the start at the file. It is used during the startup sequences by both the IOP and EE during cold boots. Usually, this feature will not be used except for when building a boot ROM image (e.g. for PCSX2).
