Recently we have been frequently reported from our distributors that there were certain amounts of counterfeit GM-816HD have always troubled them. After having a test on the fake, we found that aside from the inferior manufacturing quality the fake is, possess NO Region Free function <NOTE: 1> as it shall have in the genuine one.

In order to prevent consumers from buying those inferior counterfeits, we provide a brief comparison chart for the potential users to identify the fake from the genuine GM-816HD per attached – comparison chart here.

<NOTE: 1>: Region Free
The publication of worldwide DVD movies are divided into region 1, region 2, region 3 etc., totally 9 Regions respectively for the regions of Japan, Northern America, southern America etc.; the PS2 console bought from region-1, for example, can only play the movies designated for region-1, playing DVD regions other than region-1 is forbidden in region-1 PS2 consoles.

We’d like to reconfirm that Mars Pro modchip GM-805SL supports disc swapping function which is vital for more characters interactive in-between in multi-disc gaming such as Dynasty Warriors 4, as well as cheat-code devices prevailing on the market, Action Replay Max for instant.


This is to notice you that the protection circuit board PTR-2, which was used to be enclosed in Mars Pro GM-805SL as an attachment, has now been changed to a smaller designed PTR-5 in order to fit into both the newly designed PSTwo V-13 and the existed V-12. Installation of PTR-5 please refer to here.

P. S.
In the new PSTwo V13, Sony has re-engineered the servo circuitry for better protection of the laser module which has significantly reduced the possibility of the laser burn-out syndrome. Under such circumstance, protection board being adding on the new PSTwo V13 is not anymore recommended.
For some customers who consider a protection board being adding on the new PSTwo V-13 better than not, we recommend PTR-5 as a replacement of PTR-2 in order to fit into PSTwo V-13.
