The COH-H3XXXX main board, when initialized, searches for a MagicGate encrypted boot file in the contents of the PlayStation 2 memory card filesystem on the COH dongle in slot 1 (left). The system proceeds to boot this code identically to a retail PlayStation 2. Any files required to access external media (optical drive, hard drive, etc) will be present here, but additional libraries or game code can be loaded from the media once it has been initialized and is accessible to the COH board. No known algorithm or security code for accessing the contents of the COH dongle through the memory card interface is known to exist at present, and a retail PlayStation 2 or PlayStation 3 (with memory card adapter) cannot access the card. There is no capability to access the data on the card from a retail PlayStation 2, and conversely, there is also no capability to accidentally (or intentionally) erase or reformat the card as the security mechanisms embedded in the COH dongle magic gate chip are not openable by any retail hardware. This includes the MagicGate encryption keys [[http://wikipedia.org/wiki/PlayStation_Jailbreak#Present_and_future_support extracted from the PlayStation 3 firmware]]. Inspection of the contents of the dongle&amp;#039;s flash memory must be done via manual extraction of the data directly from the 8MB NAND flash chip. While COH dongles can be read and written by COH board, very few (if any) production games leverage the ability to write to the dongles, instead opting to use the onboard battery-backed ram on the COH board to store game settings, highscores, and the like.&lt;/div&gt;&lt;/td&gt;&lt;td class=&quot;diff-marker&quot;&gt;&lt;/td&gt;&lt;td style=&quot;background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;The Sony model [[File:COH-10020.jpg|thumb|COH-H10020 and USA packaging]]COH-H10020 security dongle is at the core of the 2X6 game boot process.

Off-the-shelf PC drives can serve as replacements, as the game will not boot without a valid sony COH series dongle and signed executable code. A list of some working drive replacements is shown below:&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

The COH-H3XXXX main board, when initialized, searches for a MagicGate encrypted boot file in the contents of the PlayStation 2 memory card filesystem on the COH dongle in slot 1 (left). The system proceeds to boot this code identically to a retail PlayStation 2. Any files required to access external media (optical drive, hard drive, etc) will be present here, but additional libraries or game code can be loaded from the media once it has been initialized and is accessible to the COH board. No known algorithm or security code for accessing the contents of the COH dongle through the memory card interface is known to exist at present, and a retail PlayStation 2 or PlayStation 3 (with memory card adapter) cannot access the card. There is no capability to access the data on the card from a retail PlayStation 2, and conversely, there is also no capability to accidentally (or intentionally) erase or reformat the card as the security mechanisms embedded in the COH dongle magic gate chip are not openable by any retail hardware. This includes the MagicGate encryption keys [[http://wikipedia.org/wiki/PlayStation_Jailbreak#Present_and_future_support extracted from the PlayStation 3 firmware]]. Inspection of the contents of the dongle&amp;#039;s flash memory must be done via manual extraction of the data directly from the 8MB NAND flash chip. While COH dongles can be read and written by COH board, very few (if any) production games leverage the ability to write to the dongles, instead opting to use the onboard battery-backed ram on the COH board to store game settings, highscores, and the like.&lt;/div&gt;&lt;/td&gt;&lt;td class=&quot;diff-marker&quot;&gt;&lt;/td&gt;&lt;td style=&quot;background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;The Sony model [[File:COH-10020.jpg|thumb|COH-H10020 and USA packaging]]COH-H10020 security dongle is at the core of the 2X6 game boot process.
