An interesting development has come up in NES emulation recently that might lead to better possibilities for console verification.
You can read about the details here:

Basically, a bus conflict exists when writing to ppuaddr ($2006) which causes incorrect scrolling to happen. The most obvious effect of this is the background glitching out.
But, a side effect of this is that it can effect sprite zero hit (since sprite zero hit requires a non-zero background pixel.)
Any game that happened to run into this in the past would fail on console since it was completely unemulated. I'm thinking Battletoads warpless probably ran into this at some point, but haven't tested for sure.
The results are still coming in but it seems completely consistent and easy to emulate. There is also the possibility that other registers (notably ppuscroll at $2005) might have similar difficulties.
This is pretty exciting since console verification (at least from my perspective looking at the emulator side) was basically stuck without any leads, and now things are starting to open back up again.
So expect some relatively big commits coming down the line. Overall very few games should be effected, but it may cause desyncs in some cases.
You can now play HuC3 mapper games in GBHawk.
RTC is untested and IR functions don't work, but the mapper runs just fine.
Probably next will be MM001 or TAMA5.In the second half, it looks like there are some places to improve (especially using deathwarps). Can input easily be hex-edited into the run? I also appreciate that you ended the run on the good (2P) ending, which I had never seen before until now. There is a 2P RTA at speedrun.com (one of the runners is the_kov) but that run kills off one of the players on the last level in an attempt to save time.
