In Monster lab, Attempting to write 65k to scratchpad crashes pcsx2.

It's obvious the reason of SIGFAULT, but it's not obvious how to solve it.
The second _GIFchain call of this game appered to have gif->madr equal to
0x80000000. Yes, it's not wery good, because *dmaGetAddr (line 341 at HW.h)
return psS as a result, start of scraptchpad memory.

But gif->qwc = 4096, so it's try to write 4096*16 = 65K to 16K sized
scratchpad.

I add following block

if ((pMem == psS) && (qwc > 0x1000))
       qwc = 0x1000;    

in Gif.cpp, line 127, after pMem = (u32*)dmaGetAddr(gif->madr); That's have
obvious meaning: if we wrote in scratchpad, we should use blocks, that less
than 16K (0x1000). And with it game now in Menus.

This issue was fixed to. And this game became playable with new idle-loop speed 
hack
with several graphical issues.
