Hi all,
While running this demo on the real thing, is the black area on SP0 hits be constant or does it flicker?
I've observed that if I remove all $2002 read trickery (necessary to pass blargg's tests), it flickers no more..
Thx.
Under my emu conditions, the program seems to read VBL flag just one PPU clock before it being set, causing the setting itself being supressed.
Now, if I remove this supression, the "black bar" on sp0 hits flickers no more, but that obviously makes my emu to fail blargg's "2.vbl_timing
" test. Nestopia, on its side, passes every test, and still shows no flicker while running s0.nes.
Any clues?
Thx.
Was it my sprite 0 tester? I wrote that before much was known about the NES PPU.
It is the one by Damian Yerrick, "Sprite 0 Test", back to 2000. Did you write it? The point is that I dunno how it is expected to behave on the real deal.
I am Damian Yerrick.
And neither do I know how it works on an NES. All I had back then were NESticle, LoopyNES, and NESten.
Nice to meet you!
And thanks for the info.

I never knew that.
I like your NSF covers.
