I guess I don't understand why creating your own arranged 2d array of colors wont work. If you pre-calculate the table then most of the math goes away, right? Such precalculated arrays might require too much space for some purposes. In any case, here's a little comparison between two algorithms. On...

For example if you use color $20, then with your sequence it will become $20, $20, $00, $00, which is not what you want since you probably wanted sometihng like $20, $10, $00, $0f. Actually Simon's Quest partially solves this problem by setting palette[x] into min(origpalette[x], (origpalette[x] &a...

Palette fading techniques
A common trick in NES games is to fade a palette to black, and back, by progressively ANDing the correct palette values with a bitmask such as 3F, 2F, 1F and 0F. An example of such game is Simon's Quest, as shown in the screenshot below. This algorithm is cheap and easy to implement. However, it is ...

I'm guessing you didn't see this: http://nesdev.com/bbs/viewtopic.php?t=8688 based on your attempts to find out how this actually works on the 6502. They actually discuss why the BRK/IRQ concurrency issue exists, as a hardware design. Just thought I'd make sure you saw that, sorry if you already ha...

Yeah, I finally saw the Kinkade painting. With the latest ROM, I get no Untested, but I get the same failed test numbers: Failed tests: 67 Failed tests: 67 63 Failed tests: 67 52 51 50 7 Feature request: Press a button to view the Kinkade painting again after test completion Allright, interesting. ...

Allright.. Will do. (And will edit this post when done.) Now what do I use the extra 8k for... That's like more than enough space to fit an emulator ;-) EDIT: Test updated. For now, the 4th bank is just going to be empty. Whimper, I felt particularly clever when I managed to reduce the graphics from...

BRK executed where should not! PC=1B00, AXYSP=00/00/05/FB/37 So it failed immediately upon landing in the supposedly VROM-loaded code. You mentioned VROM. Three CHR banks are not a power of two; might that have something to do with it? I know it's not a power of two. Does PowerPak have a problem co...

Results from new version, again depending on reset: BRK? BRK executed where should not! 01010100ar01011D7800000100 [...] Are you making sure to wait for $2002 bit 7 to be set a couple times? If you don't, reset might cause the PPU to ignore writes for a frame. I'm using Blargg's framework, which in...

Regarding the sprite-0 hits, this test only expects shed-size accuracy on the timings (about 60 scanlines). Timings are not the issue, it's whether the DMA uploaded correct data or not. EDIT: I updated the test, removing the fail-barrier before test 73. So now it should be possible to get results fo...
