And of course everybody knows about the SA-1 bugs in Mario RPG. The dialogue boxes flicker, sprites disappear when you enter an inn, etc.

I could swear pagefault completely fixed this before the last board crashed.
I'll go and check.

Edit: no flickering at all. Only trouble is that all sprites (mario and other chars) disappear while the location indicator is on.

I also had that problem, enabling (or disabling, can't remember) the new gfx engine would stop the flickering.

Edit: Just tried SMRPG, no flickering.

[snkcube]

I just tried Super Mario RPG and the flickering still appears even turning on or off the new GFX engine.

Build dependant bug ? No flickering on linux cvs, new graphic engine.

Game Name: Dragon Quest 6

Type of bug: graphic glitch

Tested on both zsnesW 1.36 and zsnesW WIP October 19

Specs: Windows XP pro SP2, 2,66 Ghz P4, 1GB Dual-Channel 266 Mhz ram, Geforce 4 Ti-4800, SB audigy, DX 9.0c

Description of the bug: In any place with both poisonous swamps and mist/clouds layer, the order the layers are displayed messes up and the cloud layer ends up under the floor layer (can be seen by disabling BG layer 2) whenever you walk in the poison. The effect remains when you get out of the swamp *only* if you keep walking horizontally, and fixes itself when you walk vertically. Disabling the new GFX engine fixes it.

If you look at ipher's and Nightcrawler's posts, you'd see it's not what everyone is using. You have the latest for a reason.

yeah well, there's not that much difference between the wip and rc output for this game so i figured it doesn't matter, if needed i can of course also post latest wip output

Game Name: Inindo: Way of the Ninja (U)
Type of Bug: Graphical
ZSNES Version: 10/24/04 WIP, Windows version

Computer Specs:

• Computer Model: Dell Dimension L700cx
  Processor: Celeron 700Mhz
  Chipset: Intel i810e
  Sound: Sounblaster PCI 64V
  Motherboard: Intel Cayman CA810
  Memory: 128MB PC133 SDRAM
  OS: Windows 98SE
  DirectX Version: 9.0b

Bug Desciption: In Inindo, when you enter or leave a location, you should get a "box-in" effect, and then a "box-out" effect to reveal what you went into/out to. (I have the cartridge, so I'm pretty sure of this!) However, in Zsnes, the screen will simply "black out" and then redraw the screen from top to bottom in chunks to reveal what you went into/out to. If you switch to the old GFX engine, the game does the "box-in, box-out" effect like it does on the real SNES.

Game Name: Traverse - Starlight & Prairie

Bug 3: In one of the houses at the first town there is a who doesn't appear, although if you disable the first and second bg layers you can see it, although it is badly drawn (this isn't fixed with the old GFX engine, and it happens in both ZSNES 1.36 and Super Sleuth too). Here are a couple of screenshots:

Confirmed, this also happens on the hardware.

The guy is invisible on a real SNES? if so, i guess he is supposed to be a "ghost" or somthin... if so, can you check if the "invisible" sprite go over top of the main character, making the bottom of the guy go invisible

Arcades Greatest Hits - The Atari Collection (U) - Confirmed

I had a hunch it would be the case... the whole 'wrong palette for 1 sprite only' isn't what you usually get in case of zsnes graphical bugs...
