Re: FamiTone2 audio library

Is it really necessary to quote random code pieces and make guesses when everything is clearly stated in the readme.txt, and is not changed since the original version? Please understand, I don't need any docs by myself, I spend quite some time and effort to write them for your convenience. Please re...

The most important improvements are: - Built-in FamiTracker text export support instead of the old TextExporter plug-in - Faster code - Smaller data size - Tempo support - Full N...

Re: SPC-700 Test ROMs should be in SPC format: Rationale

The only other device to use this CPU was a Sony VCR. Although the chip is certainly rare, I think this doc and the fact the chip is supported in this IDE shows that it had some more applications besides just SNES and a VCR. A number of VCRs, at least, as there are 9 VCR-on-chip parts listed in the...

Re: 24 fps animation

It does seem that standard 'fluid' animation on NES (Moon Crystal, for example) uses the on fours, i.e. 15 FPS. It should be noted that 24 FPS is not really a standard animated film rate. The film itself runs at 24 FPS, but the cel changes rarely gets that fluid, for the most part it is on twos or t...

The chips with the part number starting from U are labeled as UMC (a picture). The TA-marked chips does not have any manufacturer logo.

Re: 24 fps animation

It may be useful for cutscenes in retro style, like, sepia palette, and not that smooth object movements.

There are many parts, not all of them actually had numbers. This list is incomplete:

2A03 direct replacements: UA6527P, TA-03NP1 (the same, additionally marked 6527P)
PPU direct replacements: UM6538
Dendy-On-Chip (not a gloptop): UM6561A

Re: Contents of the "nes.lib" in CC65

I'm asking myself why those generic C runtime functions are implemented in a lib that's specifically for the NES anyway. Well, that's just a misleading file name. This part of code is normally called 'runtime.lib' (the source folder is called like this), so I probably should rename it after removin...

Re: Contents of the "nes.lib" in CC65

But in this case, what's the reason behind creating such a lib in the first place instead of using the one from the CC65 website? It is not creating, it is just compiling existing sources. The reason is to know what is inside rather than use a black box and to exclude all unwanted stuff (lib size i...

Re: Contents of the "nes.lib" in CC65

The nes.lib that I compiled does not have any of my code, only the C compiler runtime. There are things like math routines, popa, popax etc. Here is all what the nes.lib contains.

Re: What workflow and equipment for ROM dev and hacking?

If you don't plan to use a custom mapper or other extra hardware, you can completely develop a game using existing modern emulators only. If you will consider certain NES limitations and quirks (documented everywhere, like VBlank time, DPCM/controller bug, and so on), good chances that your code wil...

Re: sndk: SNES SDK for Linux (i686)

If you want to display static images, you probably don't want a raster buffer and set_pixel, you can just convert them into tiles. If you want to draw some static images generated in software, like vector figures or something, then you need a virtual raster buffer. I would do it with a RAM buffer (u...

Re: sndk: SNES SDK for Linux (i686)

It isn't a big deal to implement a virtual raster buffer with set_pixel, using a RAM buffer - just a few lines of code, in fact, but it'll be really slow, because a full screen update (RAM to VRAM transfer) will take about 6 frames even in 16 color mode.
