Mortal Kombat Trilogy (USA) works perfectly. Beat the game a couple of times in a row and didn't notice any graphic or audio glitches.

I was using the command-line build. When I get home I will search for an 'out of memory' fatalerror, and find what could cause it.

Hey RB, when you get up, would you mind using your magic post-deleting powers to nuke the mudlord dogpiling earlier in the thread? Spent the better part of the past 3 hours talking to him on IRC, and... he's actually pretty cool, and reminds me of me to an impressive degree.

The 'out of memory' comes from machine.c (failure to allocate memory).

The problem can be replicated simply by doing a hard reset, it is not necessary to load another cart.

The failing command is on line 3757 of src/mame/video/n64.c, in the video_start function.

state->m_rdp->AuxBuf[1] = auto_alloc_array_clear(machine, UINT8, EXTENT_AUX_COUNT);

JD: a few of the crashes I experience seems to point to the first call of a function using

Code:
rdp_span_aux *userdata = (rdp_span_aux*)extent.userdata;


as a parameter, e.g. m_rdp->TexPipe.CalculateClampDiffs(tile1, userdata, object); (but the function depends on the game), or more precisely to the first time the called function tries to access userdata items (like userata.ColorInputs or userdata->m_clamp_s_diff)

could there be any uninitialized piece of the "extent_t extent" parameter?

it might be a coincidence, of course, but maybe you could try to check, just to be sure...

a testcase for the above error is 64 Oozumo

JD: Note that the failure is on alloc; it doesn't say what hasn't been freed to cause the OOM.

Maybe, but given the size of that allocation (around 100-200 megs, probably), I wouldn't be surprised if borderline systems threw a fit if the aux span buffers haven't been freed when it goes to allocate the new ones. There isn't much else in the N64 driver that requires *that* much memory.

r14487 reduces the memory overhead of the RDP system, fixes missing text in Mario 64, takes a crack at a slightly different interrupt scheme that (interestingly) gets Clay Fighter 63 1/3 to boot without needing an insane interleave, and throws in a 64DD skeleton driver to boot. Enjoy!
