Here what Lik Sang answerd me :
Hi Jean-Marie,
We are very sorry for this and are aware of the issue.
We regret to inform you that the unit you have is not faulty.
Unfortunately, this new "behavior" looked like a fault when first
discovered, even to us here at Lik Sang. Gamepark have made an official
statement in the meantime and published the new settings for programmers to
amend their software, so there is probably not a lot that can be done to
'undo' this hardware change.
This is a official confirmation from Game Park
=================================================
We changed LCD from Samsung to Taiwanese brand very recently, which means
that some skilled amateur developers (some users of the GP32 BLU) need
to get revised setting value of the firmware to comply with the LCD
of Taiwanese brand if Game Park makes the setting value open to them,
which is our idea to resolve this issue.
Simply speaking, Game Park original software and games have nothing to do
with this issue as you may understand.
==================================================
We do absolutely understand the impact of this recent change to the GP32
hardware and regret being unable to change Gamepark's mind. There is not a
lot that can be done as all GP32 systems manufactured in the future will be
equipped with the new LCD display type.
We at Lik Sang does of course also understand that this is a hard blow to
the GP32 community and that it happened in the middle of the Christmas
rush doesn't make it any better.
We hope it can be solved in a timely manner.
More info about this issue and what is going on can be found at
http://www.gp32x.de/board/ and we know that the GP32 community is
working hard to find a solution.
But we wish to show our gratitude to our customers
(after all, you are what makes us exist), so if you still feel that
the GP32 you bought is not to your pleasure, we will except a return
of your GP32 BLU to us.
So as a affected customer of this problem, you will have two options to
solve this.
==============================================
(1) Keep the unit as it is and monitor the community forums closely.
http://www.gp32x.de/board/ I am positive that this will be solved.
==============================================
==============================================
(2) Ship the GP32 with all items back to us, with our DHL account and
get a refund. (Confirm this email and you will receive an RMA number
and instructions how to proceed)
==============================================
Once again we are truly sorry that this happened in the middle of the
Christmas rush We know it have taken some time to process all this,
and that some of you may already have received several replies regarding
this issue.
This is the final statement on how the GP32 problem is going to be handled.
So please confirm with a (1) or (2) option to this email and you will be
processed ASAP.
Best regards,
Jim Lou
