Quoting my words to clear up some misunderstanding: Rather than defective, I should say it's a relatively bad choice. For a ROM author though, it can be worked around (with NES 2.0). The thing is some people would choose not to use NES 2.0 to make ROMs compatible with other old emulators that are st...

Thanks everyone, I've got a better grasp of the whole thing. Seems that besides the HUD it could only be used in certain cutscenes at best.

On the topic of palette swaps. I've read a few documents and came to know that palette swapping between an HUD (as long as it doesn't contain sprites) and the game portion is possible and not too hard. If minor graphical glitches are tolerated, then it won't consume too much time either. However it ...

If your question is solely about sound, my personal opinion is that the VRC6 is really the superior extension sound chip. I do not like how the VRC7 sounds, but it is personal. I have more experience with NES music than most of you guys I think. In fact, the VRC6 sounds can even be simulated with N...

I initially chose VRC7 for my hack because of its advanced sound, but now I find that I can likely handle N163 sounds even better, so I'm considering switching to it. The problem is though, are there any features present in VRC7 that is not present in N163? I haven't found such features. Also, how i...

...Of course, I'm not gonna spend all those code waiting for the HBlank. I'm trying to make the scroll look like a wave. Assume that the first page and the second page are exactly the same. The following code is my code, and some graphical glitches appear at the right edge of the screen when running...

So, I've made a couple of demo PCM programs, like 7-bit 44KHz ones and MMC5 8-bit 22KHz ones. But one guy, after recording the sound from FCEUX and comparing it with a regular wav file using some software, says there seems to be some distinguishable differences. Is that the emulator/recording proble...

Well here's some problems about some assemblers. I'm working on a hack project, and my source code relies on a disassembly source which should be compiled with x816. First to note: My source uses directives like .db instead of .byte, and uses <Addr16 and >Addr16 for high and lo bytes of a 16-bit val...

A chip supports 4-screen if it has additional VRAM. But such info(whether a chip has VRAM or not) is not included in the NESDev wiki. I'm currently using Mapper 85(Konami VRC7) in a hacking project. The 2 original games which used VRC7 didn't use 4-screen at all, and the nametable mirroring control ...
