I wonder if he tested it through a copier... because this could be caused by a bad dump, couldn't it?

Yes, Confirmed on a copier using my Super Famicon. Someone with a copy of the game will need to verifiy if the dump is bad. And yes the main character does disappear when you stand behind the invisible one.

ok, only had a little time for bug testing today

Darius Force (J) - Confirmed... does this bug only happen on this one stage, or is it everywhere?

Well yes the screenshot of the boss is before the point at which I saved the zst, the zst is saved at the level after the boss. I'd play further through the game but the flashing is too bad.

Bad flashing at boss (can't really see it in the screenshot but there is a bit missing of the boss if you look close). Also happens at other bosses.

Press Pause in the BAZZA'S BLOCKADE (Both savestates have the kongs on this level) and the background part of the reef disappears, saves a snapshot etc and it turns green!! Using the old gfx engine fixes the background problem but the backdrop turning green still happens. Weird huh?

Type of Bug: Gfx
Bad flashing at boss (can't really see it in the screenshot but there is a bit missing of the boss if you look close). Also happens at other bosses.

Iirc (don't have the cart anymore, played on a friend's) Gradius was really full of sprites, resulting in slowdowns and sprite overflow galore.
This is normal behavior... but this should be checked on the real cart.

Yoshi's Island:

-graphics bug-



Check this state, press A to enter the level. This bug only seems to appear in level segments that have the "dizzy" effect in them at some point, so select a different level if you want to see how it should really look.

-graphics bug-

Also, the dizzy effect involves the ground getting all wavy, but on ZSNES that effect is stuttery and shivvery in a way unlike the real game. The ground is supposed to wave nice and smoothly. Here's a state just before encountering the fuzzies.

Starfox:

-gameplay bug-

(it's a well-known bug, but you said to post even these )

This seems to be a problem for most SuperFX (2) games, but I'll use Starfox as an example. The 3D segments simply move too fast. Proof: the first boss of the easy route is not supposed to open its bay doors until the intro tune is over. On ZSNES, the battle is already halfway once the intro music finishes. Here's a savestate just before the battle.

Winter Gold FX:

-graphics bug-

Like with Stunt Race FX (on the last version - the latest WIP plays Stunt Race FX perfectly ), there is vertical screen tearing (I don't know what else to call it).

Final Fantasy 3/6:

-sound bug-

Another well-known one, obviously. It's the same as in most square games, in FF3 it's most noticable in the wind effect. Just fastforward the intro until you get to the snowy peak. It sounds like an alarm instead of the way it's supposed to sound in the real game, namely like wind.

Super Mario World:

-sound bug-

Again, just a single example of an extremely common (and well-known) bug in many games. Simply try Mario's spinning jump, and you'll notice that the sample of which that sound effect is made up, is only played a few times, as opposed to a whole lot of times like it should. Am I right in guessing this has something to do with two instances of the same sound effect being unable to overlap? Or is it simply SPC timing?

Killer Instinct:

-graphics bug-



There should be a background, obviously. I haven't seen this bug on any other levels. The screenshot and this [url=httphttp://home.wanadoo.nl/blackmyst/Killer%20Instinct%20(V1.1)%20(U).zst]savestate[/url] are from the v1.1 US version.

When disabling windowing, the background reappears. However, then, the punching bags are drawn in front of the characters and text (which they aren't on the real hardware), and also, the characters' shadows will disappear unless you disable the new gfx engine.

-graphics bug-



The bottom of the screen is cut off. Both versions, when using ZSNES' screencap function, show this. For the US version, this accurately reflects what you see in ZSNES. However, that is not the case for EU version, for the EU version the screencap and what you actually see are different:



As you can see, the EU version doesn't cut the bottom of the screen.

Game Name: Not Game related

Type of Bug: Crash

if you change Sound Interpolation to 8-Point while a game is running zsnes crashes and goes to windows

Confirmed, though I have some more information about this bug for ipher.

This happens to me too, though it seems to depend on whether or not there is music playing, because I didn't get any crashes when there was no music playing. I tested with Bahamut Lagoon, and got Zsnes to crash if I enabled any type of interpolation when no form of interpolation was already enabled and there was music playing in-game.
If any type of interpolation is already enabled, though, I can't seem to get it to crash by switching to another type of interpolation, or by disabling it then switching to another type, even if there's music playing in-game. I have to disable interpolation, resume the game, THEN reenable interpolation to get it crash.
I also tested with Contra III and Inindo and got the same results. I also noticed with these games that I had to wait for music to play, just like in Bahamut Lagoon.
I also noticed that if sound output is disabled, either by un-checking "enable sound", or by disabling SPC emulation beforehand(and leaving the "enable sound" box checked or un-checked - it doesn't matter as long as SPC emulation is disabled), the bug is fixed.

In a nutshell: if music is playing in-game, sound is enabled,and no form of interpolation is currently enabled, and you enable any form of interpolation, ZSNES crashes.

EDIT: If I crash Zsnes with this bug, while in a window, I get a "This program has performed an illegal operation..." window, and this is one of the dumps I got after a crash, if it helps (note that a few of these values varied when I crashed the game a few times, though a lot stayed the same):

The Killer Instinct bug (the missing background) is fixed when you disable windowing.

Ah, I see. But in that case, the punching bags go in front of the characters, instead of behind them the way they're supposed to be (I just checked on my KI cart).

Yeah, this is true. A sprite priority bug perhaps?

Game Name: Gradius III (U)

Type of Bug: Gfx
Bad flashing at boss (can't really see it in the screenshot but there is a bit missing of the boss if you look close). Also happens at other bosses.

Iirc (don't have the cart anymore, played on a friend's) Gradius was really full of sprites, resulting in slowdowns and sprite overflow galore.
This is normal behavior... but this should be checked on the real cart.

If you pause the game at the boss in the sreenshot certain parts of it will flash on and off when it's paused, somehow I don't think that should happen.


Astxist

[grinvader]

Remember in Super Metroid, (on the real cart) if you do the Murder Beam glitch, that'll do it.
Pausing the game doesn't change the fact that there's sprite overload.

[ipher]

Ok, i am almost caught up on adding the bugs to the tracker, with the exception of Astxist's Gradius bug, and the last group of bugs submitted by blackmyst, we have 19 Pending bugs (ones that i still need to verify),

We have 68 open bugs, which 16 are crash bugs (3 emulator crash, 11 rom freeze, 2 from unemulated special chips) 33 games with graphic bugs (7 prevent you from playing the game, 18 are noticable, 8 "hardly noticable"), 3 GUI bugs, 3 games with sound bugs, 5 "other" bugs, and i need to find the last 11 that are still unclassified.

I guess i underestimated how many people hoarded bug reports! LOL

I am going to be replacing my motherboard, and formatting my HDD tonight, so i may not be back for a little while. Keep those bugs a comin!

Heh, I guess a little encouragement goes a long way.

My utmost respect for all the awesome work you devs are doing.

about that zelda bug, now that i see the screenshot i can remember i experienced that one too, interesting this is i'm not sure wether it was on zsnes or the real game, i finished zelda once on zsnes and three times on my real snes so chances are this might be a bug present in the real game, somone has got to test it...

None at all actually I've never bothered learning how. Iv'e never seen it happen on the actual snes, but I was playing the Pal version. I've had it happen more than once on zsnes.

I finished Legend of Zelda on the 25/5 WIP without problems... are there any changes since then that could make this possible? maybe something related to the battery bugs? I finished the game several times on a real SNES back in the day, and I never suffered a bug like that... I played the PAL version tho.

The Breath of Fire II timing bug still exists.

I found this: http://sourceforge.net/tracker/?group_i ... aid=475892

But it says the bug was deleted.
