Big wall of text forthcoming, guys, but you'll have to wait 'til the end to see what happened with The Misadventures of Tron Bonne (though I'll give you a minor spoiler: Notaz has done what, to my knowledge, nobody else ever has, with this one
).
Croc 2 (PAL) - Now working! Cutscenes now work, and obviously now that they do, so does the game itself. It requires frameskip, and has some slowdown issues, and this makes the audio a bit juddery here and there, but it runs pretty nicely at 750MHz - it is near-full-speed in many spots, but has slowness spikes in others.
Croc: Legend of the Gobbos (PAL) - Now fully working! The cutscenes that would not play in r4 now do. Damn near perfect at 750MHz, though it requires frameskip, and does slow down a little bit in places.
Rockman 8 - Metal Heroes (NTSC-J) - Now fully working, too! FMVs work (which is good, since they're fairly important here), and the game is pretty much full-speed at 750MHz (with frameskip), with the exception of locations with large amounts of activity or transparency on-screen, where it slows down (it slows down a lot with the transparencies).
Mega Man 8 (PAL) - The same as Rockamn 8 - Metal Heroes (NTSC-J) - pretty much full-speed at 750MHz, with frameskip, with some slowdown in locations with lots of activity or transparency on-screen. The PAL version's slowdown is *much less* pronounced than the NTSC version's, probably due to this version being optimised for 50Hz systems.
Klonoa - Door To Phantomile (PAL) - Runs and works, but has speed issues. The game's FMVs judder when the text-overlays are present (such as the one proclaiming the game's title, and "It's strange...", and so on, in the opening after starting a new game). In-game, it is full-speed in a few places, but mostly it is far too slow to play (and it fluctuates a lot in general). The speed is much improved over PCSX ReARMed r4, however.
Mega Man Battle & Chase (PAL) - Full-speed at 750MHz (with *very* minor slowdown issues during fade-ins/fade-outs, and in some menus), with frameskip. Perfect.
(^ This is what the headstone of my free time shall surely read.)
The Misadventures of Tron Bonne (PAL) - With the "SPU IRQ Wait" option set in the SPU-configuration, the game works damn-near perfectly (albeit requiring frameskip, and running at full-speed with the occasional "slowness spike"; I ran it at 750MHz, for the record) until it gets to the point in the first level where Teisel Bonne comments on there being a small hole in the wall (which the Servbots can fit into), and then hangs after he says "Hey, Tron...". I switched on "SPU IRQ Always Enabled" in the Advanced options, and whilst the game then functions normally again, this results in the voices being lost. After getting it past the part where it hangs and switching "SPU IRQ Always Enabled" off, the voices return and the game functions normally again. If you flip the "SPU IRQ Always Enabled" setting on and off quickly enough, the voices aren't lost - it only needs to be done to get the game "unstuck" from where it hangs.
There are other spots where this occurs; For example, after defeating the first boss, after Tron's wondering what's taking the Servbots so long, and says "Huh?", but again the same thing works to get things moving again. When starting to play the Bank mission, I noticed it again there, too, and near to the end of that mission as well. It just seems to happen at random once in a while (and it always involves speech-related activities) - I'm pretty sure it coincides with when stuff is about to happen (such as someone new speaking in the first example, the Servbots walking onto the screen in the second, and control being about to be handed to the player in the third; Of course, this could well just be coincidence - it might be totally random!). I'm guessing it happens throughout the game. Anyway, I'm not complaining at all, because it's VERY easy to work around it! I just wanted to make a note of it.
This very minor issue aside, for what to my knowledge is the first time ever in an emulator, The Misadventures of Tron Bonne works perfectly! I am thoroughly amazed. Notaz, well done and many congratulations to you.
