N64 - Bizhawk runs out of memory after some RAM searches #198

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Bizhawk 1.7.0

After doing quite a few RAM searches, Bizhawk's memory (RAM) usage will reach 
1GB. At this point it throws an error message and the RAM search can't 
continue. ROM in this case was Majora's Mask U.
I would suspect that this would also happen with other cores if not for the 
fact that there RAM search probably never uses this much memory.

I can try to manage memory more efficiently, there are some solutions there.  
In the meantime I recommend you turn off Undo when doing searches on N64 
(especially large games like Majoras Mask)

GoogleCodeExporter commented 9 years ago 
Couldn't you just limit how many steps you can go back to like 5 for N64 games? 
That should curb the memory usage, shouldn't it?

Also why does Bizhawk only use 1 GB of RAM? If modern computers have anything 
in excess it's RAM. Ofcourse as a 32 Bit program it can't use more than 2GB, 
but why doesn't it go up to that point?

we could limit the undo, sure.  Or save it to disk instead of ram.  Or both.  
That's not trivial, or top priority right now.

A 32bit app is supposed to have 2gigs or so, but in reality, a .net app will 
crash at around 1 gig, due to whatever garbage reasons.

Revision 8722 should adequately address this issue, undo now uses less ram, and 
is limited to 5 undos

I tried the most absurd scenario, Majoras Mask, 1 byte searches, and I deleted 
5 addresses one at a time. EmuHawk used a lot of ram but no where near out of 
memory errors.
