Donkey kong 64 doesn't boot up

[GoogleCodeExporter]

Describe your system:
 - Linux distribution: Debian
 - Machine type: 64-bit
 - Mupen64Plus version: svn1404 + bug 51 related patches
 - Plugins used: glide64

For visual artifacts, give:
 - MD5 118E9CE360B97A6F8DAB2C9F30660BF5
 - Donkey Kong 64 (E) [!]

Describe the problem:
It seems that the command at address 0x80603fb0 or following command (in
delay slot) isn't interpreted correctly and it causes Donkey Kong 64 not to
boot up correctly. This is a 'bne  $at, $r0, 0x80603FA4'

It seems to be inside a loop "forever" near that position. The code looks
like this:

80603FA4 lw    $t7, 0x0000($v0)
80603FA8 addiu $v0, 0x0004
80603FAC sltu  $at, $v0, $a0
80603FB0 bne   $at, $r0, 0x80603FA4
80603FB4 addu  $v1, $v1, $t7
80603FB8

And after the next round it will do an exception with cause 0x10000400.

I cannot upload it here as "project attachment quota exceeded".

Sry, this savegame is exact one round before the actual interessting bne. It 
seems
that the interrupt by itself is the problem. Somehow.

Pokemon Puzzle League 000364BAC80E41D9060A31A5923874B7 doesn't boot up either 
and
also creates many, many, many SP_INT interrupts instead. Maybe this is related 
somehow.

Don't take my comment too seriously, because I just don't know, but may this be
caused by some division-by-zero strange behaviour? In the Mupen64Plus version 
1.5 I
had, I got some division-by-zero messages just after the Rare logo (IIRC).
Unfortunately, after I compiled from the source, I didn't get those errors 
anymore
for some strange reason.

But I tried adding some checks to DIV_S for nearly-zero values, and at almost 
the end
of the intro I get one place where it's very close to zero, twice.

DIV_S 0.000003 @ 806545CC

I don't know if Mupen64Plus is accurate in floating point calculations, so if it
isn't, that might be an interesting place to look.

This rom just needs to use 4k eeprom. I will try to merge the wii64 stuff with
mupen64plus.ini later
