Getting started

+

My aim with these pages is to cover as much as possible, so you don't need to try and figure them out yourself. + That said, being able to follow along yourself will almost certainly help get more out of this. For following + along with source code, you're really going to want to grab yourself a dumped copy of a game (it's going to be a + lot easier, and cheeper, than dumping one yourself). I trust you can figure out where to find that.

+

For network related things, your options are a little broader. The ideal would be physical ownership of a + cabinet, and a subscription to genuine e-amusement. Odds are you don't have both of those :P. A connection to an + alternative network works just as well. In the more likely case that you don't have a physical cabinet, it's + time to crack out that dumped copy of a game and just run it on your own PC (or a VM, if you're not on Windows) + (odds are whatever you downloaded came with the program you'll need to start it pre-packaged. If not, it rhymes + with rice.).

+

You will also need a local e-amusement-emulating server. By the time I'm done with these pages, there will + hopefully be everything you need to be able to write your own. Unfortunately I'm not finished writing them; + depending on where you acquired your game, it may have shipped with one of said servers. If it didn't, Asphyxia + CORE will do the trick (yes, it's closed source).

+

If this all sounds like way too much work, and/or you're just here because of curiosity, I plan to prepare some + pcaps of network traffic to play around with without needing a running copy of a game or a network tap on a cab. +

Application Protocol

+

As the previous pages have eluded to (you did read them, didn't you?), eAmuse uses HTTP as its main way of + getting data around. This means we need an HTTP server running but, as we'll see, we don't need to think too + hard about that.

+

Every request made is a POST request, to //<model>/<module>/<method>, + with its body being encoded data as described in the previous sections. In addition to the + X-Compress: and X-Eamuse-Info: headers previously detailed, there is also a + X-PCB-ID: header. that can be set. Your machine's PCB ID uniquely defines the physical board. This + header is added in out-bound requests, and allows the server to identify you. Importantly, it's also the value + that the server uses to identify which machines are authorized to be on the network, and which are not. +

+

Every request is followed immediately by a response. Any response code other than 200 is considered + a failure.

+ +
+ Source code details +
+ +
libavs-win32-ea3.dll:0x1000f8e7
+
+
+ +

All requests follow a basic format:

+ 
<call model="model" srcid="srcid" tag="tag">
+    <module method="method" ...attributes>
+        children
+    </module>
+</call>
+

The responses follow a similar format:

+ 
<response>
+    <module status="status" ...attributes>
+        children
+    </module>
+</response>
+

With "0" being a successful status. Convention is to identify a specific method as + module.method, and we'll be following this convention in this document too. There are + a lot of possible methods, so the rest of this document is a big reference for them all. There are a + number of generic methods, and a number of game specific ones. If you haven't clocked yet, I've been working on + an SDVX 4 build for most of these pages, and each game also comes with its own set of game-specific methods. + These are namespaces under the game.%s module and, in the case of SDVX 4, are all + game.sv4_method. I may or may not document the SDVX 4 specific methods, but I've listed them + here anyway for completeness. +

Known services are:

+
    +
  • ntp
    • +
  • keepalive
    • +
  • cardmng
    • +
  • facility
    • +
  • message
    • +
  • numbering
    • +
  • package
    • +
  • pcbevent
    • +
  • pcbtracker
    • +
  • pkglist
    • +
  • posevent
    • +
  • userdata
    • +
  • userid
    • +
  • eacoin
    • +
  • local
    • +
  • local2
    • +
  • lobby
    • +
  • lobby2
    • +
  • dlstatus
    • +
  • netlog
    • +
  • sidmgr
    • +
  • globby
    • +
+

Most of these will usually just return the URL to the eAmuse server (or your fake one ;D). ntp is a notable exception, unless you're planning on reimplementing NTP. keepalive will likely alsop be a custom URL with query parameters pre-baked.

    Encryption is performed after compression, and uses RC4. RC4 is symmetric, so decryption is performed the same as encryption. That is, packet = encrypt(compress(data)) and data = decompress(decrypt(data)).

    Encryption keys

    Encryption is not performed using a single static key. Instead, each request and response has its own key that is generated.

    These keys are generated baesd on the X-Eamuse-Info header.

    This header loosely follows the format 1-[0-9a-f]{8}-[0-9a-f]{4}. This corresponds to [version]-[serial]-[salt]. TODO: Confirm this

    Our per-packet key is then generated using md5(serial | salt | KEY). Identifying KEY is left as an exercise for the reader, however should not be especially challenging.

    LZ77

    Packets are compressed using lzss. The compressed data structure is a repeating cycle of an 8 bit flags byte, followed by 8 values. Each value is either a single literal byte, if the corresponding bit in the preceeding flag is high, or is a two byte lookup into the window.

    The exact algorithm used for compression is not especially important, as long as it follows this format. One can feasibly perform no compression at all, and instead insert 0xFF every 8 bytes (starting at index 0), to indicate that all values are literals. While obviously poor for compression, this is an easy way to test without first implementing a compressor.
