    I have Sonic Jam, and I noticed that sonic 1 has spindash in it. could it be possible to hack out the rom leaving a sonic 1 MD version with spindash? I was reading that someone did this for sega smash pack. also, sonic 2 could have different features?

    I have tried to see for myself but the game freezes a 10 seconds. (damn girigiri!)

    any ideas? :huh:

    Sonic Jam doesn't contain ROMs. The games were ported to work on the Saturn, with no emulation involved.

    About the only thing you'll find is data about easy, normal and hard modes and time attack. That's about all you should expect. Of course I don't know about Sonic Mega Compilation (GC) since I don't have a gamecube. :huh:

    I don't think so, but then again, I've never played SMC.

    Ok. If that can't be done, has someone stopped girigiri from freezing at 0:10 on any sonic game within sonic jam?

    HAHA! *pwnz you all for having a Saturn*

    I'm working on porting the Sonic object from Sonic 2 into Sonic 1. That should bring with it the Spindash. Then it's a simple case of finding the relevant sprites for the Sonic 1 "Spindash", insert and voil?.

    Knowing my luck it won't be nearly as simple, but meh.

    SORRY!!! I didn't know! It's my mistake! Don't Get angry about it!

    I'll hit myself for it! :wacko:


    I've only looked at the back of the box, but SMC just has S1, S2, S3, S&K, SS and Dr robotniks mean bean machine (I'm not sure if there's 6 games or 7 don't yell, wait I'm going to far whoops...). No 3D. That's why it sux. Does anyone know if it has spindash on Sonic 1?

    No, it does not have have spindash.


    However, all the contents of SMC are about 1000MB big, now, don't tell me they could cram all of that into Sonic Jam.


    Remember, SMC also ad movies and comics, which Sonic Jam did not.

    And, in Japan, you could get Comix Zone and... some other game.

    Sonic Jam has: (I have it)

    Sonic 1 with spindash
    Sonic 2
    Sonic 3
    Sonic & Knuckles (Can pick which game you want to "lock on")
    Every sonic manuel (Japanese & English)
    + Sonic Art
    + Sonic history until Sonic Jam (1997)
    + Sonic World
    + Sonic Sketches (and character details)
    + Sonic Japanese Ads And Sonic CD JAP intro&outro
    + Strange Sonic Anime type clip

    Do you get THAT much in sonic mega collection?

    Also, I think they were able to "jam" that much on by using their own codecs and stuff for the movies (smaller) and lower frequency music. (remember, the sonic games used the chip in the MD for music, which saturn didn't have, so they just recorded them off in pieces)

    Well, actually there are 3 versions of Sonic 1 in Sonic Mega Collection.

    1 is the US version (code to select)
    1 is the JP dump we have (code to select)
    1 is the JP version with the spike bug fix (default)


    Sonic Mega Collection also has Blue Spheres (Sonic 1 locked onto Sonic & Knuckles)
