Generally the emulation only includes raw [[hardware logic]], such as for the [[CPU]] and [[RAM]], and specialized [[digital signal processor|DSP]]s such as tone generators or video [[Sprite (computer graphics)|sprites]]. The MESS emulator does not include any programming code stored in [[read only memory|ROM]] chips from the emulated computer, since this may be [[copyrighted]] software.

Obtaining the ROM data by oneself directly from the hardware being emulated can be extremely difficult, technical, expensive, and even destructive since it may require [[decapping]] or [[desoldering]] of [[integrated circuit]] chips from the [[circuit board]] of the device they own. A desoldered IC is placed into a chip reader device connected to a [[USB]] or [[serial port]] of another computer, with pin sockets on the reader specifically designed to match the [[chip package]] shape in question, to perform a [[memory dump]] of the ROM to a data file.

Removal of a soldered chip is often far easier than reinstalling it, especially for extremely small [[surface mount technology]] chips, and the emulated device in question will be destroyed beyond recovery after the ROM has been removed for reading.

However, if one has a working system, it may be far easier to dump the ROM data to tape, disk, etc. and transfer the data file to one's target machine.
