AKAI DVPS-760

It has been reported
that the region setting of the Akai DVPS-760 can be changed from
the remote. This has not been verified. If you try this method,
please report whether or not
it works by visiting THIS forum.
1. Open the disc tray
2. Push SETUP on the remote control.
3. On the remote control, push the following buttons:
X 1 0 1 0
(where X = your choice of Regions 1 through 9;
Region 9 = BYPASS/REGION-FREE)
STEP
SHUFFLE
NEXT
4. There will be nothing shown on the screen as you perform Step 3.
You MAY be able to
verify whether the region actually was changed by doing the
following:
a) Open the disc tray
b) Push the following buttons on the remote control:
SETUP
SHUFFLE
STEP >|<
NEXT >>|
This will reveal a "secret menu" screen.
5. Push the down-pointing arrow on the remote
until the DEBUG menu appears.
6. If the check-mark on the right column
matches the number you chose for "X" in Step 3
(your desired region choice), then you are done!
In the example illustrated above, "9" (Region 9)
was chosen for "X" in Step 3.
THE DEBUG MENU DOES
NOT ALLOW YOU TO
CHANGE THE REGION
SETTING. IT ONLY LETS YOU
CHECK THE REGION
SETTING. YOU MUST PERFORM
STEP #3 ABOVE IN ORDER TO CHANGE THE REGION SETTING.
NOTE: The firmware
should be "RCE-proof", so selecting Region 9
should play ALL DVDs without problems, including
RCE-encoded discs.
WHAT ABOUT MACROVISION?
At this time, there is
no known Macrovision hack for the DVPS-760.
You may have noticed that the region hack for this model is very
similar to
that of the Daewoo DVD-5700/5800/6300N and Hyundai HDP-380.
HOWEVER,
THE FIRMWARE FROM THOSE PLAYERS WILL NOT WORK
IN THE AKAI DVPS-760. DO NOT ATTEMPT
TO LOAD THE DAEWOO OR HYUNDAI FIRMWARE IN THE AKAI DVPS-760!
DOING SO WILL RUIN YOUR
PLAYER!
The first step in
developing a Macrovision hack for the DVPS-760 is for the
player's factory firmware to become available for download.
If you are knowledgeable about removing firmware chips,
extracting firmware, and/or modifying the firmware, the
information provided below should be helpful.
Pictured below is the player's main circuit board.

The firmware chip is the one labeled "SST", located to
the left of the large
"ESS" chip. Because the chip is soldered to the board,
it cannot easily be removed and
read in an appropriate chip reader.
Note, however, that the
SST chip is sitting inside the "pad" for
a larger, 32 pin chip. It might be possible to drop a 32-pin
socket "over" the
39VF080, and then extract the firmware with a
standard 32pin EEprom reader.
Here are the details of the "SST"
chip:
Exact labeling on the chip: SST MPF 39VF080, 70-4C-EI, 0151079-B
