IPU: VQ not implemented

[GoogleCodeExporter]

1) Did the game ever work correctly?

Not implemented...

2) What steps will reproduce the problem?

When loading the first intro logo after the MC and disclaimer screen.

3) What exactly happens when you experience this issue (listing any console
errors or screen output you recieve)?

This: http://img220.imageshack.us/img220/9137/corrupt.jpg

The console spams "IPU: VQ not implemented" (in red flashing letters) along
with really corrupted graphics and a noticeably framerate drop.

4) What version of PCSX2 are you using? On what operating system?

PCSX 1533 / Windows XP Pro SP3

5) Please provide any additional information below.

Game title is Hisshou Pachinko Pachi-Slot Kouryoku Series Vol.7 - CR Fever
Powerful Zero. Pressing start allows the game to play normally though it
seems to get stuck at the IPU error if start is not pressed.

This is not an issue at all (which doesn't mean it doesn't exist), thought
the block dump could be useful for implementing whatever is missing, or
just documenting for future testing (if a rewrite of the IPU comes at some
point).

Game uses RenderWare, MTGS must be On to avoid graphical corruption on more
recent PCSX2 revs.

Though other games published by D3 don't have this issue, the games vary
from developers. VQ is codec related ?, it might be different than the
rest. As I told before, feel free to drop the issue.

VQ decompression is extremely easy -- nothing more complicated than a palette 
lookup in 
fact (ie, like displaying a 256 color image to true color display). I coded 
some VQ 
compression and decompression algos years ago.  Fun stuff. :)

In any case, assuming PS2's VQ is similar or the same, implementation should be 
trivial.  But I won't be working on it for some time, have many other things I 
have to 
do yet.

Submitted this as a test case mainly, is really redundant and I can't remember 
the
other game developer involved (not D3) to look for possible similar cases. 

Also the game might be the only case since Pachinko games are usually heavy in 
FMV
content while this is really light, due to this the FMV seems to be packed 
inside a
container.
