Press F11 to decrease sound fx and F12 to increase sound fx.

[j4m3s]

it increase sound 2.. i think in real arcade the ingame voices from time extention is much more louder? maybe im wrong.. rev 239 is out!!

It's because Model 3 Cabinet has three speakers one for the engine sound, two for the sound effects and ambient sound and third for the music


BTW: Bart, are you going to redump the Virtua FIghter 3 romset because I've seen a bunch of missing textures in certain stages (ex Akira and Pai's) in the future?

[Bart]

Sometimes it's good to take a long break and look at problems with fresh eyes. Today, I spent half an hour playing around with Virtua Fighter 3 and discovered that only one of the four ROM patches I apply is really necessary to get the game to run. When that last patch is removed, the game behaves like the VF3TB ROM set: it locks up just before attract mode at the 'Sega' screen but can still be played by setting it to 'Free Play'. The game runs about 2X too slow, like VF3TB, but I noticed something very interesting: the character models don't break up at their joints anymore, as in VF3TB. It all makes sense now. It wasn't a problem with the 3D graphics after all (as I had mistakenly thought) -- it was a timing problem that probably resulted from objects being moved slightly too far from frame to frame. The geometry and textures still get screwed up; that's another issue altogether.

When I get some more time, I'm going to try to make sense of the subroutine below, which is what is currently patched out. I can see right away that it has something to do with timing. The decrementer (dec) and time base (tbl) registers are polled and there are some loops that wait on variables in RAM, meaning IRQs are involved. I'm putting optimization and clean-up of the 2D renderer on hold (that can be done later, the hard part -- layer priorities -- has already been achieved) and will be examining this over the next week when I can find a few minutes of spare time. The first task is simple: I just have to translate this into C-like pseudo-code to make it more readable for myself. Then I have to do the same with the relevant IRQ handler (or whatever other routine modifies the RAM variables being waited on). That's when the hard part begins: making sense of what it's trying to do. It already looks rather nasty. It's pulling in lots of magic numbers from various places in RAM, which is always a headache to deal with.

Check the Video Memory Test, you may notice a FIF0 Error

Don't worry about any of those. They don't involve the ROMs. The VROM tests don't actually access VROM data, either, and are irrelevant. Only CROMs can be read and if the ROM test appears to fail, it's only because I've patched the ROMs to get them to run. Trust me, the dumps are fine.

Today, I spent half an hour playing around with Virtua Fighter 3

Oh Sweet Baby Jesus!! VF3 playable without the graphical glitches in the (may I guess) near future??!! I can hardly contain myself.

They still have graphical glitches, but Bart is still working on it right now at that moment, but it is likely in the Near Future without graphical glitches
