    It works! Simply rename the rom to "rom.bin" and SSH it in.

    Tried:

    Sonic 2
    Golden Axe
    Altered Beast

    All worked flawlessly (aside from having only 1 button) but they ran at full speed with NO stuttering of the sound, which is normally an indicator of an optimized emulator.

    The only quirk I saw was when Sonic 2 ran through its "demo play" the graphics were screwed up and scrambled, but when I started it and played, worked great.

    Now I dont mean to piss on SEGA, but I can see some hacker modding this code to make a wicked fullspeed Genesis emulator for the iphone.

    Just tried Gunstar Heroes, got a message:

    "Developed for use only with PAL and French SECAM Megadrive Systems"

    Damn....

    So im guessing that its limited to domestic games.....and 1 button :p

    Interesting, hopefully someone will hack this official 'emulator' to support multiple buttons, and more games. genesis4iphone isn't a bad emulator but it'd be great to run games at full speed with sound.

    So it runs other games better than the one it is suppose to emulate?

    Hilarious!

    Im pretty sure it will work, the point is once someone with code-writing skills gets thier hands on this, I foresee a nifty genesis emulator incoming. SEGA cant close this pandora's box.

    Kinda ironic how in pursuit for the best genesis emulator, SEGA itself in the end provided it.

    Well, this thread is going to get locked soon, but what I found interesting is that instead of creating an iPhone/iPod Touch game, they just created an emulator and slapped a rom in it. So any other game they release at five bucks is pure profit because none of their other games will have any production cost.

    Fascinating.

    As nice as that would be, it is not really possible. Just because you have the end executable does not mean you have the source code. It is extremely difficult to reverse engineer a source file, let alone try to decipher how it was built and what other files it calls or uses. I have a feeling Zodttd (creator of many iPhone emulators) will be studying this for sure, but it will not be as easy as just dropping the executable into a new emulator.

    I tried Vectorman and it crashed, along with Sonic 3...so not all games are working, at least for me.

    Do you need a jailbroken iphone to do this, or is there some way to do it with the regular system?

    Can you rename the emulator so as to have multiple roms on the phone at the same time?

    Can you change the icon?

    I wasn't going to buy Sonic, but I would buy it if I could play multiple games.

    Frankly, if Sega came out with a best of collection for $20, I would buy that too. I did when they came out with the PSP version, so why wouldn't I get it for the iphone.

    SSH into your iphone (assuming its jailbroken) then look in:

    "USER > APPLICATIONS > ######### > SONIC 1.app"

    In the folder is the actual game itself in rom form, unsuprisingly named...."rom.bin".

    Simply find a rom of another game (you'll have to find your own rom resource sry) and rename it "rom.bin" overwrite the original, voila'.

    Start it up and witness the magic.

    I totally agree with you, I believe Zodttd stated that the reason for the stuttering/slowness in his emulators was related to how the touch controls were hogging resources (aside from the iphone OS), maybe in studying this code he could recognize some efficiencies he missed.

    Fascinating, yes...and the very reason why I railed against Sega doing only this after one year of singing the iTouch/Phone platform's praises.

    It's a good idea in terms of business, but sheer lazy cowardice creatively.

    And anyone who thought it was to be any different other than an emulator running a rom was fooling themselves. Sega has been doing this since the days they had officially emulated releases for PC and Dreamcast. In fact, I wouldn't be surprised if the emulator used to run this game isn't a modified version of the one they used for the Sega Smash Pack on Dreamcast.

    In fact, the issues that some here are raising with the rom files are the same issues some had with the hacked Smash Pack all those years ago (they hacked the Smash Pack to run other games).

    Shame that Sega could've done this AND given us new content. But Sega...Sega doesn't seem like Sega anymore. :(

    hope thsi thread isnt locked, emulation has such a massive potential and whether or not sega realise it, theyve opened up a massive can of worms here!

    anyways, there is a perfect PC sega emulator, for master system, genesis and saturn roms out there in the public domain. loads everything ya chuck at it. not going to give away its name, should be an easy find ;) but true emulation for this system isnt difficult at all.

    We just talked about this one our podcast, but, It would be cool that when 3.0 comes out. Sega jsut makes an app called Sega Flashback, and you can use micropayments to buy roms.

    Honestly (and this is just my opinion)

    Porting Sonic this way, without changing practically anything, is a one-man job. I mean, honestly, with Sonic being one of SEGA's most RECOGNIZABLE names... why didn't they make more effort?

    My iPod is already jailbroken... I've downloaded various emulators and whatnot.

    Why would anyone pay for this? Especially if you own it on the original console (like I do)

    Not really. It doesn't emulate Sonic the Hedgehog. It emulates Sega Genesis/MegaDrive hardware, and runs the Sonic rom on the emulated hardware.

    The issue is that back in those games a lot of the Sega games were developed in assembler, and used various aspects of the hardware that may make for differences in difficulty running on the emulator.

    Again, the issues some have raised lead me to suspect this is a reworked version of the emulator used in the Sega Smash Pack.

    Or just but the Sega Flashback app and supply your own roms...
