    Keep up the awesome work, I can't believe how fast you've hacked this game. <strike>By the way, do you have a short guide for the max rings cheat(for the wii version)? I already have Cheat Engine but I'm having a hard ass time finding the address for rings</strike> nevermind, saw the post on page 3 that said to use artmoney instead of cheat engine.

    Hate to be so bothersome, but is there any chance we could just get a .wad of Sonic 4 with fixed physics attributes? If not, then what exactly must be done if we would like to do it by scratch?

    I believe Jim and/or Endri said we'd all know when they'd worked out how to alter things like that.

    What with physics being the main complaint about the game, do you really think they'd ignore them, or not tell us if they'd fixed them?

    Well, Endri did fix them in that video he put up on page 3; unless I must stand corrected.

    The reason I ask is because it was a release done for the 360, which requires your 360 to be j-tagged to edit. A .wad file edited from the Wii version of S4 would make this hack much more open to the public; since it is playable on most computers via Dolphin.

    Shoot, sorry; I forgot everything had been done on the 360 so far; I thought it was just the Wii. :specialed: In that case, I fully concur! :D

    I remember Endri mentioning some fixes now, although IIRC they weren't as extensive as most would prefer.

    You can't just magically use the same executable from a 360 game in a Wii game. There are no Wii physics fixes, and probably won't be a for a while.

    Well, I knew that, but I thought it was said at some point that the code to all the versions of Sonic 4 was identical, meaning that every version could be edited the same way.

    How exactly would such vastly different platforms share identical code? Even if the original source was extremely similar, they'd compile differently.

    This is why we can't just do it in 5 seconds. We need to disassemble the executable and find the code for things in new locations and edit it there. I personally am not experienced with PPC asm, so you'll need to wait for Endri to do something with it most likely.

    Something that's been bugging me. Sonic 4 has BRSAR files. I tired using HCS's unpackers, but it doesn't seem to work.

    Hey, I need some help.

    I need to get the speed shoes in these 4 acts, because either they're too difficult to find in the act or they forgot to put tvs in some of them:

    1.) Casino Street Act 3
    2.) Lost Labyrinth Act 1
    3.) Mad Gear Act 2
    4.) Mad Gear Act 3

    I was figuring I'd post it here since it looks like you can replace a TV box with some hax, which would be easier for me to record the rest of the music from the Wii version without playing each act 1092379837592375 times just to find some god damn shoes. If there are ways to get the speed shoes in these acts, please do tell - because I can't find any of them. I just need a savestate near each act that needs speed shoes so I can record the rest of the songs that I'm missing.

    I'm very close to recording the entire Wii version soundtrack, I just need these 4 songs and I can releaseeeeeeeeeeee.

    The BRSAR format doesn't cease to be updated thus rendenring most of the rip tools outdated and useless.

    But doesn't the format stay static with the game it's with? EX: game x has an older version and can still be ripped from while game Y has the latest version and needs a new ripper.
     
  15. Sonic 4 can be hacked? Good, now hackers can make it decent.

    What he's saying is that, at the time the tools were released, the version of BRSAR it was compatible with was an older version of the one used in Sonic 4

    Ah, so we don't have a version of the tools compatable with the current version of the file type yet. Now I get it.

    I created a soundfont using the .RWAVs from the BRSAR file in the Wii version. You can grab it <a href="http://dl.dropbox.com/u/38216/sonic4wii-soundfont%20wip.7z" target="_blank">here</a>.

    Please note the following before complaining:

    - There's lots of room for improvement here. I did this in 4 hours with Viena, and it was all I could do without going insane.
    - Lots of things are mislabeled or aren't labeled at all (Fart, etc...), so if you choose to care, please correct my mistakes.
    - I tried to make the presets for the drums similar to the Ultimate Genesis Sound Font. Depending on the MIDI file, you might need to tinker around a bit to get the sound you want.
    - Speaking of drums, I created two different presets for the drums. One has Sonic 1/2 DAC samples (with the Sonic 4 hat sound), and the other has "GM" Drums. The GM Drums are a little incomplete, but they should be usable. There were some other snares/kicks that don't sound like they come from the same bank, so these samples I left for you to toy around with.
    - For some reason, FP Studio doesn't see the presets anywhere for this soundfont. I think I made a booboo somewhere, please correct this mistake so it works. I tested in LMMS, and that will find the presets fine. (EDIT: I THINK I GOT IT NEVERMIND)
    - There were a lot of instances where most of the samples were just higher noted versions of the previous sample, but I included these as well just in case. You might be able to do something with these, but whatever

    tl;dr - please fix any mistake you find, or add any improvements that you feel is okay. I'm not familiar with creating soundfonts at all, so this was my first go at trying to make one. If there are mistakes, obvious errors, etc - please fix them yourself.

    Enjoy...

    (PS: I still need those 4 speed up mixes of those songs for the Wii version so I can also release the Wii version of the soundtrack - plz give savestates to speedshoes in those acts that I mentioned earlier thhx)

    Apparently, walls and ceilings are automated. If this is true, would this render the likelihood of a full physics fix impossible?

    They aren't automated, just incredibly sticky.
