Sonic Advance 2 decompilation

Pretty cool; the Advance games really don't have much in the researching and ROM hacking scene (the only hack of the series I could find was one of Advance 3 that changes the text... and that was all).

 

Someone page the Vita homebrew community...

Sonic Advance on the Vita as an actual port would be very nice.

 

Nice to see someone accepting the challenge from SHC earlier this year, to look at games that have barely been modified, or not at all.

 

This is immensely exciting! Sonic Advance 2 was also one of my formative Sonic games and I think cracking this open will lead to fantastic places. Obviously, the most immediate of those would be a PC port of the game in widescreen, perhaps even cleaning up some of the more unfortunate level design snafus, but imagine character mods! Imagine an accessible level creation tool that could bring about a dedicated Advance 2 hacking scene! Advance 2 in particular is a game that has never really been done again, particularly with regards to the simple yet wonderfully freeform trick system that affords players so many movement options. I hope this'll lead to fan projects that wring every last drop of potential out of Advance 2's gameplay.

 

As someone working on their own disassembly (and to a much lesser extent a decomp) this is impressive stuff! Well done!

 

Considering Sonic Advance 2 is the one game I ever seriously Speed ran, it's great to hear it finally getting some attention from hackers... and now I wish I could fire up VBA to play this game again... Or still had my original cart and DS and could play them.

 

Same. So with this could it be possible to maybe port this to PC with more screen space visible so maybe said game would be more playable?

That's the dream right there (oh that and a mod that overhauls the bullshit emerald system that game had. Literally the ONLY Advance game that made you get the the emeralds as every character and they were basically impossible to get to unless you memorized the level)

 

One really cool thing that Sonic Advance 2 has are the bosses that you have to fight while running. I saw some Tails Skypatrol fanart on Facebook of Tails chasing Witchcart, except they also added Sonic running on the ground while also chasing her. This got me thinking about how it would be cool if someone were to bring back Witchcart as a boss for Sonic to fight in a fangame or hack where the battle took place in a Sonic Advance 2 boss fight setting. It's not something I have ever seen anyone do, and in terms of bringing the most obscure characters into games this would be one of the least expected. With this decompilation, such a thing could be easier to achieve by using Sonic Advance 2 as a base.

 

Extremely excited to see where this goes.

 

What's your best time for Sonic Advance 2? Last year, I put a ton of effort into the Tails category for Speedrun.com's leaderboard. [LINK]

That's really exciting. So is the previously unknown team mode similar to what we got with Sonic Advance 3's team mechanic or does it function very differently?

 

@willy: I feel like this should be in a PM, but I can't find a button or link on your post that appears to initiate a PM, but my Sonic Advance 2 times can be found at:

Lost my original Advance 2 cart many years ago(I think it might have been before I ever got a DS, though I was late to the DS party, buying a refurbished DS Classic because it had been discontinued in favor of the DS Lite by the time I upgraded(I have big hands, I only put up with the GBA SP hand cramping tininess because the original GBA didn't have a built-in screen light)) and never really felt up to starting over with a new cart or trying to speed run on an emulator, but I'm still ranked #20 overall for Advance 2 on The Sonic Center despite how long I've been retired(granted, I don't think Speed Runs.org existed back when I was active, so some of it might be The Sonic Center losing activity to a more general speed running leader board...

More to the topic, while I never really had anyone to play against for multiplayer on the GBA(and the need for multiple systems, one or more link cables, and sometimes multiple copies of the game to access all multiplayer modes didn't help), it's kind of cool there was a unused multiplayer mode... WOnder what Cream's assist would have been had the mode been finished... Part of me says it would have been cool if either player could do a Cheese attack even if that would be even more game breaking then in single player(pretty sure Cream was the first character I managed a no game over run from Leaf Forest to the end of XX and the first I managed to max out the score counter on simply because Cheese shredded all of the bosses and made getting an 80k time bonus against the bosses trivial).

 

Jeeeez, if speedruns were a thing in like, 2002-3 when I got my first GBA SP along with this (my first game for the system) - I would've probably fucking *killed* it. I had all the locations of the ring emblem icons memorized in every act as well; so I could get it with all the emeralds, each time; first try.

I don't know if I ever got nearly as good at a game as I got at Sadv2, weirdly. I thought I was pretty good with NiGHTs, but recent replays remind me that in the later 3 levels getting those A rankings is a *bitch*; I lost my memorization skills.

Even if I tried, I don't think I could ever be as good at Sadv2 as I was when I was 12/13 and had like all the time to practice, lol...too much going on these days.

 

I really wonder what other unused discoveries will be found, as the Advance games really aren't well documented.
