NES playroutine identifier
I have started work on a configuration file for sidid, but instead of identifying C64 players, it identifies NSF players. I have also created a small modification of the original program, so it looks for NSFs instead of SIDs.
The signature file is not complete, but I'd like your thoughts on this.

Re: NES playroutine identifier
I was actually thinking of integrating something similar into my NSF player. Consider me interested.
Re: NES playroutine identifier
HertzDevil had a similar idea.
It's not traditional to use .exe with UNIX executables. You can usually detect the difference between UNIX and Windows by the absence or presence of the COMSPEC environment variable.
This makefile incorporates COMSPEC as well as three other changes:
It's traditional, if a required argument is missing, to recommend on stderr that the user run programname --help.
Usage is somewhat confusing, as it works only on directories, not individual files.
I ran it against the development folder for my own music engine, whose source code can be browsed:
Any tips on making signatures that are distinctive yet resilient to minor changes in new versions of the engine, beyond those listed on the sidid GitHub project?

Code: Select all
# Use .exe only on Windows, which defines COMSPEC
ifdef COMSPEC
DOTEXE:=.exe
else
DOTEXE:=
endif
EXENAME:=nsfid$(DOTEXE)
.PHONY: all
all: $(EXENAME)
$(EXENAME): nsfid.c
gcc $^ -Wall -O3 -s -o $@
- You can strip debugging symbols from the output while linking by using -s in the command line that produces the executable.
- Use two automatic variables so that the makefile doesn't repeat itself: $^ means "name of all dependencies", and $@ means "name of the target".
- Target names that do not refer to an actual file, such as all, clean, and the like, need to be declared .PHONY so that Make doesn't get confused if there's an actual file by that name.

Re: NES playroutine identifier
Been a while since I posted anything related to this. Here's a new signature file, with a whole lot more added :)
And sorry, but no update to the program. I am not proficient at all in C++ :/

Re: NES playroutine identifier
This update only contains the config file, and the link with the actual program in the first post is dead.

Re: NES playroutine identifier
Another update. I also added information to the unknown id's in the nsfid.nfo file, so if you have any info on these then please feel free to tell me.

Re: NES playroutine identifier
I decided to look at how you're detecting Pently in the new cfg:
You've correctly determined that pentlysound.s is on the whole less volatile than pentlymusic.s. I matched both snippets to parts of the pently_update_one_ch subroutine there:
Code: Select all
Damian_Yerrick
DE ?? ?? 10 ?? BD ?? ?? 9D ?? ?? B5 ?? 85 ?? B5 ?? 85 ?? 18 69 END
(Pently)
BD ?? ?? 1D ?? ?? D0 ?? A5 ?? D0 ?? E0 08 F0 ?? A9 30 9D 00 40 END
- The first snippet is the "playback rate divider" and "fetch the instruction" parts of sound effect envelope processing.
- The second snippet is the code immediately preceding it, which mutes a channel if its sound effect has finished and its instrument is silent.
Re: NES playroutine identifier
Another update.
I'd like to ask out of curiosity, is anyone actually using this tool for anything? If so, then what for? Don't worry too much about the answer, I'll continue work on this regardless :p

Re: NES playroutine identifier
Hey, Karmic, do you think you can post this up at like GitHub or something? (People could push updates to the database.) It would be nice if this was also incorporated into NSFPlay and VirtuaNSF too.
Re: NES playroutine identifier
Seems like a good idea, but I have a hard time thinking that anyone would actually bother. Aside from HertzDevil maybe, but I think he has his own solution already.B00daW wrote:Hey, Karmic, do you think you can post this up at like GitHub or something? (People could push updates to the database.)
Re: NES playroutine identifier
Time to update this thing again.
Note that "?FCP3_Unknown_1" is a player used on quite a few Famicompo Pico 3 entries, but due to the compo's anonymous nature I can't provide a proper name for now.

Re: NES playroutine identifier
Another small update with only a few fixes for existing IDs. Still 356 unidentified NSFs in Knurek's archive.

Re: NES playroutine identifier
I am definitely going to be messing with this program. I have skimmed through all the files and I'm about to fire it up soon.
