Has someone attempted to do a physics hack yet? is it possible to replicate genesis-style sonic physics?

I'm curious as to why no one hasn't yet or hasn't spoken up if they have.

If I am not mistaken there is no hacks yet because almost everything in the game is stored in AMB files - we can unpack them but currently there is no way to pack them back in. So, no physics hacks until we have proper AMB tool. All we can do now is to simply swap models and textures.

Sneak Peak of a little something I'm working on, Sonic 4 Episode 1 iPad textures for the PC version.

In these comparison pictures, the first is the original PC version texture, the second is the iPad version texture with the PC version shiny effect, and the third is just the iPad version texture. Once I'm done with converting the iPad version textures so they can be used in the PC version, I'll share both textures packs here, a pack with the iPad textures + PC shiny effect and another pack with just the iPad textures.

Hey dude, how are you managing to do this? It's really cool, because presumably you're repacking textures and what not.

After a bit of searching yesterday found that someone make a script for quickbms that allows to unpack and repack the PC version AMB files (also works for the iPad version):
quickbms - http://aluigi.org/quickbms.htm
script - http://aluigi.org/pa.../bms/sonic4.bms

I'm not sure about this, but it's likely that to repack the amb files, the filesize of the modified files have to be the same as the original filesize. I haven't really tried putting textures with bigger or smaller filesize though, so far I've always made it so the modified textures have the exact same size as the original.

I've tried bigger and smaller files, it only accepts it if the file size is exactly the same.

Thought so.

Anyway, progress so far.

Well thats news to me! wish someone said something sooner instead of letting me ramble on like a jackass.

So this AMB tool, is there any word someone is working on one even from a non-sonic community? I know some of the GTA modders made tools we use over here.

Sonic comparison:

Wow, I actually didn't think there would be a difference like that from the PC version to the iPad version. In fact, I actually expected them to look pretty much the same.

I must say though, I actually really like the way the iPad one looks by itself the most. Not too big a fan of the shiny effect..

[deadmaster]

Thought so.

Yeah, that was with trying to replace music and sfx though. I can unpack amb files with the quickbms script, but for some reason repacking them isn't working...

Super Sonic comparison:

I suggest that you keep the shine on Super Sonic, since he's traditionally shiny anyway.

Anywho, I lie in wait until Sonic is turned into Scourge and/or Shadow =P

To repack you need to use the reimport shortcut, then select the script, select the AMB, and in the end select the file you want to reimport (if you want to repack multiple files, the tool will automatically reimport those other files as long as they're in the same folder as the one you selected).

About the textures, I've been trying a few things, I might do a 3rd pack, using the iPad version textures without the "shiny" effect (dunno what's the technical name for this, but that doesn't really matter), but I'm editing the textures to lower their brightness a bit.
Later today I'll post some pictures with the results.

Small update, been messing with the brightness of the textures, while at first it seemed nice, it would mess too much with white parts (for example, it made Moto Bug eyes grey instead of white), so I tried something else, instead of messing with the brightness I tried messing with the gamma, and these are the results:

1st picture is default PC texture, 2nd is iPad version texture with PC shiny effect, 3rd is just the iPad version texture, and 4th is the iPad version texture with the gamma lowered to 0.85.

Sonic's skin is no longer ghostly pale, and his blue looks far more like it should. Definitely a huge improvement of all those gamma-adjusted shots. For some reason, it's only the 360 version (and PC by default) that has the models looking for brightly lit. Really can't understand why.
