Homebrew [Release][N3DS] Sonic 1 & 2 (2013) Decompilation port

[JeffRuLz]

This is a 3DS port of Rubberduckycooly's decompilation of the mobile versions of Sonic 1 and 2.

On a New 3DS they run at full speed almost all of the time outside of special stages.
Special stages are playable, but run at a low frame rate.
On an old 3DS the games are too slow to be enjoyable.

!!! Read the Setup Guide !!!

This is amazing. Thank you! hoping to see those special stages worked out

yooo! this is great
i don't have a copy of sonic one or two (i have 2 on my 3ds, but i think you need a steam copy of it to work) but this is amazing!

I fucking love this community. Awesome work.

Hope to someday see full-speed special stages, and maybe even better old-3DS performance. Oh, and an AIR port. And $10,000.

You don't. The google play version is free and you can find the apk all over google--follow the guide above its ubber easy
( should also note some versions didnt work for me 3.3 or something i ended up using the1.4 update for sonic 2 )

just a thought: have you actually considered porting sonic 3/K/AIR?
i don't expect you to but it would seem possible, albeit a bit harder since you need sonic 3 steam and also all the coding to get it to work again.

I hear the bit with AIR in particular is that it's closed-source, and you'd have to ask the creator of AIR for permission to port it.

I have but AIR is closed source.
If I understand correctly AIR works by interpreting code on the fly. While a normal computer can handle that no problem it might be an issue on a weak handheld console.

Aside from the frame skipping in special stages, the ports play really good!
Sonic 1 looks good, but Sonic 2 for some reason looks garbled.
EDIT: Fixed by deleting "settings.ini", which came from the PC port.

Adding a dot-by-dot screen mode (via 800px mode) would make those look better!

Any way to access the DevMenu?

Eh this is one case where I don't see the point of 800px. Aligning most 2D assets to 400px is already as sharp as it gets, the extra resolution only helps with rotation and the special stages that already run too slow.

Set DevMenu to true in the settings.ini file, then it'll show up on the pause screen.

Or a ntsc composite video mode.

cause... I guess I'm the only one who cares. Need some way to hide that dithering.

Having a problem - no sound. This applies to both Sonic 1 and 2.

Do you remember if you had dumped your dsp file?

 

[MurraySkull]

What dsp file?

 

[DominoBright]

What dsp file?

Install the cia, run it, wait for the music to finish (you'll get the DSP file so Sonic audio should now work), then press B to delete the cia as you'll no longer need it.

Thanks! However, JeffRuLz has never said anything about that.
