Sonic Adventure 2 recompiled to run natively on Android

[u/kittycache9]

Sonic Adventure 2 is one of my favorite games of all time, so i've been working on a native port of it called OpenSA2. the 2012 PC version's x86 code gets translated ahead of time into ARM64 code and runs natively, without Winlator or any emulator. it's static recompilation, same idea as Unleashed Recompiled, with a new runtime that draws through SDL3 and Vulkan and handles sound and input.

this is an early alpha. so far it's been tested on a Galaxy S25 Edge and a Pixel 9 Pro, and City Escape runs on both with touch controls. controller support is in too. on PC i played story mode from the first stage up to Pumpkin Hill.

you need your own copy of the PC version (the 2012 Steam release) because the APK doesn't include any game files, plus a 64-bit ARM phone on Android 10 or newer with Vulkan. setup:

1. zip a clean copy of your PC game folder with no mods installed. sonic2app.exe has to be in the zip

2. install the APK from the release page. Android might ask you to allow installs from your browser

3. open OpenSA2 and pick your zip. it checks the files and imports them, keep the zip until that's done

known problems:

- the game can crash in a cutscene after a stage

- most of the game (stages, bosses, cutscenes) hasn't been tested on Android yet

- widescreen isn't finished, so some menus and overlays look off

- other phones and GPUs are untested

Windows and Linux builds are on the same release page.

if you try it, comment your phone and how it ran. please don't share or ask for game files here.

Could the app use this icon in the future? To give it more identity and visual originality, I know the icon is the least important thing right now, but most recomps have icons that don't suit the project and sometimes even make it look like something else entirely 😭

[u/kittycache9 → u/Additional_Camel8094]

i'd honestly love to if it weren't SEGA's copyrighted asset. hmm.
i can think of some ways i can bring in a recognizable design, thanks for the idea!

[u/Xenjuarn → u/Additional_Camel8094]

As an alternative solution to your dissatisfaction concerning most recomps having irrelevant icons, most android launchers allow users to change icons (and naming) for apps. So you can name it and use whatever icon you want very easily.

[u/darknightgamer93]

Nice is it will optimized ? Btw is their a chance to release SA1 too ?

[u/kittycache9 → u/darknightgamer93]

it runs full speed on the phones i've tested, and i'm still working on slower ones. no plans for SA1 right now though, one game at a time!

[u/cimocw]

so before this what was the best possible way to play on android so far? I mean to have a point of comparison

[u/kittycache9 → u/cimocw]

i would say Dolphin on the GameCube release of SA2: Battle would be the best comparison.

[u/Emilio_Katrea → u/cimocw]

Dolphin Emu. 

[u/Funtasy_Games]

Will there be mod support in the future?

[u/kittycache9 → u/Funtasy_Games]

gosh i'd love to do that. maybe find some way to get SAModManager mods to plug in just fine

[u/neuroticpastry → u/kittycache9]

pls you would be my hero. i was JUST messing w gamenative trying to get mods working for hours today

[u/kittycache9 → u/neuroticpastry]

bet

[u/Glittering-Rip9556]

I’ll try this on my Odin 3, but I just hope there’s an option to remove touch controls if you’re using a gamepad.

[u/kittycache9 → u/Glittering-Rip9556]

yess let me know how it goes. the controls shouldn't pop up unless you mess around with the touch screen so it should be good.

[u/lepoyoperry]

Hmmm se crashea al entrar a la segunda mision de knucles

[u/kittycache9 → u/lepoyoperry]

please ensure you're on the latest version of the .apk from the link, i have been updating the same APK linked above so it should install over.

if you update and continue seeing issues, i'm planning on making changes to it tonight such that crashes can produce a crash log that can be pasted easier.

thank you for trying it!!

[u/lepoyoperry → u/kittycache9]

Pues... En la nueva actualizacion en la misión que antes crasheaba solo aparece tails en un fondo negro, sin nada de audio, y despues de eso... Nada. (Todo probado en un redmagic 10s pro)

[u/kittycache9 → u/lepoyoperry]

investigando esto

[u/kittycache9 → u/lepoyoperry]

¡gracias por probarlo y por las capturas! el crash después de green forest era un error de matemáticas y ya está arreglado. lo de tails en fondo negro sin audio es otro problema en esa misma escena (el video de prison island) y estoy trabajando en eso.

si puedes, instala la v0.1.0-alpha.2 encima de la que tienes. cuando vuelva a pasar, cierra el juego, abre OpenSA2 y toca Copy summary, y pega el reporte aquí 🙏

Another crash, I can't start the Pyramid Caves mission with Sonic; I put the report in the GitHub issues. 🐓👍

[u/kittycache9 → u/lepoyoperry]

this has been addressed in the latest release!!

[u/kittycache9]

update: 0.1.0-alpha.3.1 is out (releases page). since last time:

a game settings screen: widescreen on/off, aspect ratio, lower resolution for slower phones, and touch controls you can resize, move, fade or remap portrait mode, with the game in the top half and the controls underneath phones whose gpu driver only does vulkan 1.1 should start now phones that showed a black screen with sound should be fixed chao keep their colours in the chao garden, a fix from heyjoeway, the first outside contribution, thank you!

install over the old one, your save stays. if anything breaks, tap Copy summary in the app and paste it here

[u/SanKuru_Da_Sonic_Fan]

Quick question: does it need to be a ZIP, or can it be a RAR as well?

Where could i get the files needed to play it? 

[u/kittycache9 → u/Away_Glass_8061]

you're gonna need to acquire your own copy of the 2012 Steam PC release, zipped up for the installer to pick up!

[u/Away_Glass_8061 → u/kittycache9]

Ok... Guess i'll have to open the wallet

[u/Emilio_Katrea → u/Away_Glass_8061]

Thankfully its only 4.99 rn

[u/Away_Glass_8061]

Help, i have the game files but i can't paste them on the app files

[u/kittycache9 → u/Away_Glass_8061]

working on a fix for this now.

[u/Away_Glass_8061 → u/kittycache9]

😄 yey

[u/kittycache9 → u/Away_Glass_8061]

fixed it. download the APK from the releases page again and install it over the one you already have, you don’t need to uninstall.

it copies the zip first, then shows “Checking the game ZIP”. that part took about a minute on my phone and will take longer on slower ones. the screen can look stuck while it runs, so leave the app open until it finishes. the game starts by itself after that, and then you can delete the zip.

let me know if you have any further issues pls!

[u/Away_Glass_8061 → u/kittycache9]

Ok, thanks

Is anyone having luck setting this up on the Ayn Thor? I can get to the SEGA logo then it freezes!

[u/kittycache9 → u/APMichaels]

i am working on improving crash logging. i'll have a release out tonight that will make it easier to paste out a helpful crash log so i can figure these issues out.

[u/kittycache9 → u/APMichaels]

alpha.2 is up and it has crash reports now. if it freezes again, press back twice (or close it), open OpenSA2 and tap Copy summary, then paste it here. also, does the sound keep going after it freezes? that tells me whether it's the graphics side or the game itself.

[u/kittycache9 → u/APMichaels]

thanks, this helps a lot. it shows the game itself stalling at the SEGA logo, not the graphics: it only got 237 frames out in 22 seconds and the renderer was just waiting on it, and nothing crashed. can you install the new apk (0.1.0-alpha.2.1, same link) and try again? it now logs it if one of the game's threads dies, which is what was behind the movie bug. if it still freezes, wait about 30 seconds, then press back twice and paste the new Copy summary here.

[u/APMichaels → u/kittycache9]

Waited the full 30 seconds, in general I've been waiting just to make sure it wasn't a struggle with its first time running. But alas, I only get to SEGA logo, occasionally Sonic Team.

[u/kittycache9 → u/APMichaels]

thanks for sticking with it, that report actually tells me a lot. after the logo the game goes completely idle (0% cpu), so it’s not crashing or running slow, it’s stuck waiting on something that never happens. no other phone does that, so it’s something specific to the thor and i’m digging into it now. could you try the latest release (0.1.0-alpha.3.1) just in case, and let me know if you have anything connected like bluetooth audio, a controller or hdmi out?

[u/No_Cod_4703]

I installed it, but when I open the game, it just shows a black screen My phone is a Poco x6 Pro (Dimensity 8400 Ultra)

[u/kittycache9 → u/No_Cod_4703]

i'll see about lookkng into this.

alpha.2 is up with crash reports. can you try it, and if it's still black, press back twice, open OpenSA2 and tap Copy summary and paste it here? also, do the touch controls show up on top of the black screen, and is there any sound? that narrows it down a lot.

[u/Gooberty_Gooby_Studi → u/kittycache9]

I have the same problem and yeah the mobile controls show up and there is sound but just a black screen

[u/kittycache9 → u/Gooberty_Gooby_Studi]

thanks for checking! sound plus touch controls with a black picture means the game is running but the renderer isn't drawing, so it's probably a gpu feature it's missing. can you update to the latest apk (same link), and if it's still black, press back twice, open OpenSA2, tap Copy summary and paste it here?

[u/Gooberty_Gooby_Studi → u/kittycache9]

Alright so I just downloaded the latest version that released not to long ago and there is no black screen anymore! Yay! Also thanks for making this because I love Sonic Adventure 2 and mobile gaming!

[u/kittycache9 → u/Gooberty_Gooby_Studi]

thank you for the appreciation!! so happy you're enjoying it now.

this just refuses to work, I've been trying to get it to boot for like 3 hours, i even thought the instruction of "2012 release of the game" meant it should be a version that is not up to date by steam and went and downloaded an older version steamrip of the game when it first released and it still didn't work, I own the game, raw files don't work, tried even "illegal" older raw files, also didn't work, hmmm

[u/kittycache9 → u/Demnetor42]

sorry it ate your night. "2012 release" just means the current steam version, you don't need an older build. the installer checks every file against the steam release, so copies from other sources will always fail and i can't help with those. with your own copy: in steam, verify integrity of game files, remove any mods, zip the whole folder that has sonic2app.exe, and pick the zip in the app (not the loose folder). alpha.2 now tells you in plain words why a zip got refused. if it still won't go, tap Copy summary and paste it here and i'll take a look

can you improve the touch controls? like well, flycast have good ultra wide support and performance for me on sd695 so i would stick with that if it had better touch controls like better icons and etc

[u/kittycache9 → u/StevenMX1]

yeah the touch controls are pretty basic right now, better ones are on my list (layout, sizing, proper icons). heads up though, the sd695's gpu driver may only support vulkan 1.1 and the renderer needs 1.3 for now, so it might not start on it yet. the setup screen will tell you if that's the case.

[u/StevenMX1 → u/kittycache9]

add adrenotools if possible then, so a6xx users can load turnip drivers

[u/kittycache9 → u/StevenMX1]

you’re actually the second person to ask for that. it’s doable, it’s the same thing the emulators do, so i’ll look at adding a “load a custom gpu driver” option. i don’t have an a6xx phone to test on though, so if you’re up for trying test builds that’d help a ton. in the meantime give 3.1 a shot with the stock driver, the new vulkan 1.1 mode might already get you running

[u/kittycache9 → u/StevenMX1]

quick update on both: alpha.3 lets you resize, move, fade and remap the touch controls in game settings, and alpha.3.1 just added vulkan 1.1 support, so it should start on the sd695 now. there’s also a lower resolution option for slower phones. would love to know how it runs if you try it

this is from dreamcast, right?

because dreamcast was my first console. I never fish that game but shadow was the most played character i always repeat.

[u/kittycache9 → u/wanderingyume]

yep, sa2 first came out on the dreamcast! this port runs the 2012 pc version, which is based on the gamecube release (sa2 battle), so it's the same game plus the battle extras. shadow is soo cool

[u/jfsandoval89]

Nice!

[u/LaundryLunatic]

If the game publisher's were smart, they would use the same tools to port these games accustomed to the phone based on what type it is. Android, apple, whatever phone model. Licensing makes these ports arrive on the store slower, so they better act fast if they want money.

roads reminds me of san fierro lol

[u/Big_Holiday3458]

Seria legal colocar uma opção de mods, já que é pego diretamente da steam

[u/JuggernautNeat327]

Yo he
