If I wanted to change the controls, how would I do so?

One my laptop screen the spots during the intro sequence have white outline and the center is black. One one of my monitors they appear black (i.e. fully black screen). On my other monitor they render correctly.

Screenshots don't seem to show the problem:

They are rendering just using the primcolor:

RGB0 = (0            - 0           ) * 0            + Primitive   
  A0 = (0            - 0           ) * 0            + Primitive   
RGB1 = (0            - 0           ) * 0            + Primitive   
  A1 = (0            - 0           ) * 0            + Primitive   

The primcolor is set to 230, 230, 230, 0, i.e. no alpha. I suspect the Canvas is being composited inconsistently because the alpha is not being set.

I'm loading Super Mario 64.z64 and I'm getting this as soon as it starts executing it:

Error! Exception :Unknown op: 0xa4000430, 0x0020fffd

It used to work with Chrome 21.

Hi

Are you still working on this project?
I'd like to tell you that it's very inspiring, as well as the blog, and it made me begin a GBA emulator.

So I was wondering if you could provide some homebrews on the main page, that can be run in one click?

I made this myself: I gathered almost 700 ROMs with the permission of the authors and I plan to make them playable directly from the project's page, as soon as they work properly.

(nothing much yet, but it's coming...)

Thanks!

Zelda OOT and MM both seem to run into a similar issue on the name select dialog.

Both seem to be using a G_CYC_2CYCLE combine mode which uses the primitive color (white) for rgb and select Texel1 for the alpha:

01374 e3000a0100100000 gsDPSetCycleType(G_CYC_2CYCLE);
01375 e200001c0c184240 gsDPSetRenderMode(IM_RD|CVG_DST_FULL|ZMODE_OPA|FORCE_BL, GBL_c1(G_BL_CLR_IN,G_BL_0,G_BL_CLR_IN,G_BL_1) | GBL_c2(G_BL_CLR_IN,G_BL_A_IN,G_BL_CLR_MEM,G_BL_1MA) /*0x0c18*/);
01376 fcffadfffffd9238 gsDPSetCombine(0x00ffadff, 0xfffd9238);
RGB0 = (0            - 0           ) * 0            + Primitive   
  A0 = (Texel1       - Texel0      ) * 1            + Texel0      
RGB1 = (0            - 0           ) * 0            + Combined    
  A1 = (0            - 0           ) * 0            + Combined    

In both cases they don't seem to be setting Texture1 correctly. OOT loads both latin and romaji glyphs into Texture0 and Texture1 and so is rendering the romaji glyph.

MM doesn't seem to set Texture1 at all in this part of the display list and is showing a broken CI tile used earlier in the scene.

If this were G_CYC_1CYCLE then I think Texel1 would get mapped to the next texel of texture0 (see here). But they do seem to be selecting G_CYC_2CYCLE.

Hi I am getting this issue in the web gui for a certain game:

Warning! Unhandled savegame type: SRAM.

Just curious, is there a timeline for implementation of certain features?

Super Mario 64 Boots Up at 30 to 60 then gets to mario head 7487 then it's super laggy from there?

Any way To Fix?

Hello Great emulator :-)

I jump in the Super Mario64 go to Open Door in the first world but not continue because crash.

0x802d5d9c: virtual readS16 failed - need to throw refill/invalid

GoldenEye runs well with LLE audio disabled (skipAudioTaskEmulation = true) but seems to crash after a minute or so with it enabled.

I've noticed that it seems very sensitive to timing issues. For instance, at some point the COUNT register was being incremented at 2x the expected rate (once per instruction rather than per 2 instructions) and the RSP seemed to get ahead of the CPU and overflow some internal buffers (wrapping around in dmem) and corrupt internal state. Since fixing that issue the RSP no longer seems to crash but the game appears to become deadlocked (nothing running on the RSP).

There are some European countries such as Germany where the Z and Y keys are switched around: https://en.wikipedia.org/wiki/Keyboard_layout#QWERTZ

To not need to bend fingers, Y should be mapped to the same key as Z.

The textures themselves are being decoded ok

The tiles are configured with G_TX_WRAP at 16 pixels:

RDP is set up with bilinear filtering:

In the case of the star it's being rendered with texrect:

02636 e4404078003c803c gsSPTextureRectangle(242,15,258,31,G_TX_RENDERTILE,0,0,1,1);
cmd2 = 0x00000000, cmd3 = 0x10000400
st0 = (0, 0) st1 = (16, 16)

Some possibilities:

• texture lookup in the fragment shader using float UVs is too imprecise
• texrect coords are slightly off (it's generating st1 of (16,16) but maybe this should be (15,15)?

Is there a way to profile this emulator? In particular I'd like to know why the "star-wipe" animation at the start of Mario 64 is slow while the Nintendo logo isn't.
