Hello

I didn't make any change to the old cpu core recently ; so I think the 
new core already has all the patches I added to the old core.
bus error can have a lot of sources ; most of the time the problem is 
not that the program wants to access a specific memory region that we 
don't handle, but it's that the program crashes due to non emulated cpu 
behaviour and will then try to execute code at random memory, eventually 
leading to a crash.

(see the high number of games compilation on STF that crash with bus 
error because the .ST image is damaged, which gives corrupted data after 
decompression)
