Newcomer's Board / Re: Need Programming Advice
« on: March 04, 2015, 04:02:34 am »
    You'll probably want to learn another language, C/C++ are good options and not as hard as people often make it look like imo
    • There is no programming langague called C/C++ (as it is so often see on the net  :-\ ) but there is two separte languages known as C and C++ (as well as dialects of those, which can very significantly in an incompatible way)
    • C++, while a good language by itself, it a horrible language to start learning. Whoever ever had the idea to make someone start programming using C++ should be flagellated. C++ is as far as I know the most complex programming language in existence, and the number of concepts to assimilate to have a real understanding on what is going on is very high. You should first learn both C and any object oriented language before starting to learn C++ in my opinion.
    • BASIC is the caveman grunts of programming languages. There is hundreds of completely incompatible dialects, the features are typically very limited and it encourages you to write non-structured programs.

    Also see If programming languages were <T>, particularly If programming lagnagues were languages (although I strongly disagree with the assmbly=latin comparison)

    EDIT : Why does this [/list] Always comes back after each edit ? Is it a forum bug ? It is quite annoying.

    Newcomer's Board / Re: How to replace music in NES Metal Gear?
    « on: March 03, 2015, 12:13:22 pm »
    Yes. There is typically a music engine that is called every frame, as well as an interface (or "trigger" as you say) that would give orders such as "play sound effect #34", "play song #4" or "turn the volume down a little", etc...

    What you'd probably want to do in your case it hack Metal Gear's music engine to support extra sound channels for VRC6 (or if it is similar enough you could use the engine from Akumajo Densetsu, Madara or Esper Dream II, since they are all by konami, there is chances the interface (or "trigger") if not identical is similar enough so that you can use them. You could make it play songs form those 3 games, and if it works, then you could hack in any song you'd want assuming you figured out the musical bytecode that makes the music format.

    Of course supporting more channels eats more RAM so if there is no RAM free in Metal Gear anymore you'd have to move the sound engine variables to sit in SRAM expansion - not a big deal. If the sound engine expect more zero page space however, you could have quite some issues to make it work.

    Another, probably even harder, alternative would be to screw Metal Gear's sound engine completely and replace it by Famitracker's, a modified version that can play sound effects as well of course. Then you should make your own interface that converts Konami sound engine's interface to Famitracker's.

    So the .nsf files that Famitracker spits out aren't usable in that context?
    No.
    Quote
    I thought that was the point of .nsf, was that it could be read on a real NES.
    Yes. It cannot be used within an existing game though, obviously, simply because the game does not use Famitracker's sound engine, because it didn't exist yet.
    Quote
    When you say editing music in a hex editor, does Famitracker count as one of those?
    Surely no, Famitracker is no hex editor.

    Quote
    My question is, rather than spend time trying to decipher someone else's code, would it be easier to rip the art assets and sound effects and redevelop the game wholesale?
    It could be easier yet, but 100% illegal, as Metal Gear is copyrighted.

    Feels like it's like the 342th time I see a projet like that. :huh:

    My tools were formerly written in Java, but I finally (phew) converted all of them to another, executable, programming language. I think it was a terrible design choice to make them in Java for multiple reasons, but back then it was the only programming I could use for modern PCs that had file I/O.

    Now I am very glad I learnt to use C and the bases of C++ correctly (trust me it's no simple task, especially C++) but it's worth it as the languages are compilable. There is also other issues with Java other than the lack of compilability (yes, gcj is supposed to compile Java programs into native executable files but I never got them working).

    Usage of the JVM is not easy and is confusing for novices who are already new to the command line. I can't count how many complaints I got because of this. And I have to admit that even for myself it was hard to use my own tools because of that, I had to look up how to invoke the JVM properly every time, so it annoyed me just as much as other users (I made the tools first for my own personal usage, and then I share them so that they can be useful for others too).

    The syntax for Java can be horrible whenever you need something *not* to be object oriented, which turns out to be pretty often. It encourages you to write unstructured programs. And you have to use the "new" keyboard all the time. The language is based on the lack of memory management, thus on the fact that you will constantly waste memory that will be garbage collected later, which can potentially be source of inefficiency.

    For all those reason I'd advice against Java for new designs :) However, I have to admit that OO is much easier to understand and apply in Java than in C++. Don't learn OO with C++, just learn another OO language and then learn how to apply it to C++.

    PS : Oh, to answer your question, download my tools, and you might find an archive with the "old" java version in them. You are free to study them in any way, just don't hope to get any support for those versions, they are officially deprecated.

    I first though this thread was an advertisement SPAM, but then I saw you were the author and thought, oh, it's not spam...

    Lately I cannot afford to buy anything else than the necessary, concretely that means mainly food, dentist fees and train abonment. But I am not less happy, on other side buying stuff you don't need is useless and takes space.

    I found the bug. It is at line 336 of gba_instr.cpp
    To fix it, replace

    Code: [Select]
    if(!inst_type&0x07) continue;
    by

    Code: [Select]
    if((inst_type & 0x07) != 0) continue;

    I'll include this fix in the next release

    Newcomer's Board / Re: Correspondence between ZST and SRM?
    « on: February 20, 2015, 08:14:26 am »
    Save states don't have to contain the same data. They depend a lot on the exact internal emulator design. Various timing details are sure to differ greatly.
    A game could rely on the state of SRAM to run, and behave wrong or strangely if the save RAM is modified unexpectedly (this is what happens if you would load a save state without SRAM information and load SRAM with another unrelated .srm file).

    In SNES case the system have more SRAM than the cartridge, so games are unlikely to use SRAM for any other use than saving, *however*, in the NES it's the exact opposite, games are unlikely to use SRAM solely for saving as it is typically larger than system's RAM.

    Quote
    Ugh, I learned that the hard way when me and my brother were both playing Chrono Trigger some many years ago. We were both using save states and normal save files, and the save files kept getting overwritten by our use of save states.
    Same here. Although used cleverly, you can have much more saves using less files, you can use up to 10 save states which themselves contains 3 saves (in the case of CT) so you can have 30 saves at a time without dealing with copy/pasting/backuping either SRAM or save state files manually, which can in turn be very practical, for example to access any point of the story quickly.

    Unforutnately save states are not always portable between different versions of the same emulator.

    I'd also add that normally the content of the SRAM (SRM) should also be included somehow in all emus save states (sometimes, as in SNES9x' case, in compressed form).

    This is probably what you should look for. The rest of the original game is re-translated, too but I don't see how that could be bothering.

    Programming / Re: ZSNES Changing sample 44100Hz to 43200Hz permanently
    « on: February 18, 2015, 03:22:02 am »
    Oh MAN this is unbleivable. When I google 43200Hz, first I find this thread, and then some other pseudo-scientific bullshit that makes absolutely no sense, like just the thing us scientists really don't like.

    So first of all - Apparently the pseudo-scientific bs is about the A frequency, not about the sampling rate. Therefore, changing a sampling rate will not affect the tuning of the music.

    Even if you changed the sampling rate down to 43200Hz, there is chances that your computer's sound card will internally resample it to 44100 or 48000 internally before the ADC, because those are the two widely used industry standard frequencies. Note that the sound card should resample it with proper antialiasing making this resampling unnoticeable from an user viewpoint.

    Second, the SNES sampling rate is internally 32000 Hz, but it is possible when emulating it to get a higher sampling rate, which can result in clearer and crispier sound in some specific cases. (For instance, Chrono Trigger uses drums with playback rate higher than 32kHz, thus using them in such an emulator or SPC player will increase the quality as opposed to real hardware. For most games it won't make any difference). The effect will be the same when using 43200 or 44100 because those are extremely close - the harmonics are gained in both cases.

    Finally, if what you want is lower slightly the pitch so that a A would be 432 Hz, this is possible to do without changing the sampling rate, and just adapt the SPC player core. However, this won't make any difference other than the pitch being 32 cents lower (which is unnoticeable to people which does not have "absolute hear", which means almost everyone including most good musicians).

    Finally I must say not all games respected the A=440Hz conventions for multiple reasons, programmers were free to make it pitched like they wanted. If they wanted to have a different A, they did. (and trust me, they really did, i.e. I wouldn't surprised if half of the SNES games does not have a 440Hz A, which nobody cares since nobody notices)

    Last but not least the frequency of the SPC700 is itself variable, normally it should be 32000 Hz, but according to anomie they found significant variations in different SNESes. Which means the pitch of an A could vary just as much depending on the SNES it runs on / depending on the emulator's tuning.

    I remember an old version of SNES9x which played music with higher pitch, for some reason it sounded quite nice.

    there is 43200 seconds in a half day
    Well at least this part is true. For the rest....

    Also 43200 samples per second have nothing to do with 43200 seconds... :banghead:

    Oh I misread your "EDIT" part. Of course when you change the switching mode it changes everything like on all other mappers in existence.

    34
    I strongly suspect that no emulator implements the $5130 behaviour since no (commercial) games ever used this register for CHR switches. Do you test in emulator only ?

    Also, why do you edit the title to say "solved" if your problem isn't solved ?

    35
    Contrary to (almost) all other NES mappers, CHR bank are counted as actual banks, that is, the size of the switched bank matters for the number you'll going to put. In other words, the MMC5 automatically shifts the value left when using a bank size greater than 1k (if this makes sense to you).

    In your particular case, I belive you should use $24 and $25 instead of of $22 and $2a, and you'd have the same result as the below code.

    Your input file should be encoded in UTF-8, it appears you are using another encoding (probably ISO-8859-5), so you should first somehow convert it into UTF-8 before processing.

    What actually happens is that the last character, 0xc9, makes it belive it's the start of a multibyte UTF-8 sequence, and "eats" the following quote, thus reporting a missing quote.

    If this bothers you, you could remove the UTF-8 decoding code in main.cpp at lines 315-330 and simply replace by the statement
    Code: [Select]
    c = s[i++];, that should work (although I cannot guarantee it will).

    Newcomer's Board / Re: How do I translate a Russian Mega Drive game?
    « on: February 11, 2015, 03:26:33 am »
    It seems all you really need is a hex editor which supports table (TBL) files using either UTF-8 or ISO-8859-5 encoding, so that you can use cyrillic writing in your table file and see the text appear correctly in your hex editor.

    Using a dummy TBL file to read nonsensical text sounds as hard as editing raw HEX in my opinion.

    Also there is no such thing as "english letters" or "russian letters".

    It's not just "a bit less grinding" on GBA/PSP, it's "it's hard NOT to be OP".
    I haven't played the GBA version more than once so I can't say for sure, but it's true it was incredibly easy/dumbed down as opposed to the original, I won't disagree. Although the original is way too grindy for my taste.

    It's more the lack of requirements for any kind of strategy which makes the game too easy rather than too quick level-up. In later FFs, the boss requires some strategies that makes them almost undefeatable without them, no matter what your level is.

    The problem is that FF1 did came out before such ideas were implemented, therefore attack or running are about the two only strategies you can do, and they had to rely on grinding requirements to make the game feel "hard". Combined with the "Innefective" attacks, this worked well but hasn't aged well.

    I was thinking that maybe it was a proprietary format that gets decoded in memory when the game is loaded in memory, and that the decoded version is then sent to the Playstation's sound chip.
    This is impossible : The Playstation can't play uncompressed sound at all, so after decoding the proprietary format, the game would have to re-encode in VAG format, which is a complicated and lossy operation, that would take much of the playstation's CPU processing power, so it'd be an awful technical choice.

    For that reason I'm pretty positive no game use other codecs than the ones natively supported by the Playstation sound chip.

    Quote
    In fact I couldn't properly copy them off the CD-ROM image (bin/cue pair) by using the normal Windows file copy functionality.
    This is absolutely normal and has nothing to do with security, as XA uses error correction data as actual data instead, so windows think the file is corrupted and displays an error. Only dedicated tools that call low level functions to access the CD-ROM (rather than the normal file handling functions) can correctly rip Playstation XA audio/video files.

    Have you tried to use PSound ? Or PSMPlay ?

    This also "proves" that the file is using XA audio, as if it was using anything else, the error correction would have to work normally, and you could open the file with Windows.

    Also, while we are at it, the Playstation do not care at all what is the name of the files on the CD. If the game was programmed to play sound starting from sector #x, and if the sectors contains valid sound data, then it will just play them happily, ignoring completely whether the corresponding file is called "XA", "XAS", "STR", or anything else.

    I am not totally sure about this but a developer who wanted to be evil enough could even split the data in multiple files and/or merge it with unrelated files, the Playstation would ignore it entierely when playing streamed audio/video. I might be wrong on that last point, though.

    40
    There is only 2 formats sound on the playstation can be played : XA and native (sometimes reffered to as VAG), which is some kind of evolution of the SNES' BRR.

    I doubt any game use a format other than these 2, if they do they'd have to re-encode using VAG by software because the playstation can't even play uncompressed sounds natively.
    In any case if it's not XA then it should be "VAG", but if the file is called "XAS" then I think it's simply another name for "XA" and that the sound is actuallly XA.

    The best way is to play it in an emulator that supports the sound debugging and see.
