I always appreciate when people test changes, I was just pointing out that when something is announced as having glitches, then bug reports about such glitches are redundant smile

it would be different if you find something screwed up to the point to be unplayable: in such a case I would like to have a save state to that point (I have had no time to get to the end of the game yet, but I will probably be able to test extensively only some of the paths to the end, because there are a few levels which annoy me a lot wink )

Earlier today, R.Belmont posted a link to NES accuracy test ROMs.

The tasvideos site tested MESS 0.146u2 which was release July 2012.

I ran the tests against MESS SVN -r 28466 (current as of this morning). Here are the results:

Results of MESS SVN -r 28466 on NES accuracy test ROMs

The results were mostly the same, though in some cases (like MMC5) there were improvements (like the ROM actually loading).


The link to the ROMs on that site 404s, so here is an updated link: NES test ROMs

There are notes for that specific test (blargg_nes_cpu_test5/cpu.nes) on the tasvideos site:

Quote:
blargg_nes_cpu_test5 fails probably on powerpak because the test is wrong? the NES may differ from the standard 6502 undocumented opcodes for this failing instruction. Someone should investigate it.


If it's failing on a real NES using the PowerPak, it might not be a reliable test.

Yeah, although if the test fails on the NES because it expects stock 6502 undocumented behavior and we aren't showing that now that's a real bug in m6502.

Can I vote for putting these in the softlist if they're not already? The fact that they're already 404ing...

Many of those tests fail on real hardware, so... shouldn't MESS fail them as well?

Or has somebody actually tested that they work when burning a real ROM, rather than using a Power Pack?

Oh, good point! smile

To verify, I reran the test on current svn and it does fail.

I am checking out MESS 0.146u2 (svn -r 16699) and will rerun the test after it's finished checking out and compiling!

Edit:
Dangit. 0.146u2 might have been before MESS and MAME were in the same svn.

I was able to install an old precompiled binary from an ubuntu deb package for MESS 0.146u2.

I reran the test and it does pass.

ICE: I don't think they've been tested without a Power Pack, but it would obviously be nice if someone did do that so we can be sure correct is correct.
