Homebrew Would a Syobon Action port be a feasible idea?

[CeeDee]

It's been ported to Nintendo DS, Wii, and has an open source remade version available. And besides, it's a really fun game. Anyone think it'd be a good idea to port it to 3DS?

 

[Roboman]

The open source version makes this orders of magnitude easier.
I may look into porting it to lpp3ds.

But I'm busy with another project for now.

Too many ideas, too few devs

The only non-trivial part is the fact that there isn't a good SDL port for the 3ds.

 

[CeeDee]

The Wii port has a source available as well - see if that's more readable than the OpenSyobon.

I ported Open Syobon to the 3ds.

It' lacks sound at the moment but it's easy to add it. At the moment it's playable but before I release it I have to fix some rendering problem, add sound and adapt graphics to the 3ds screen resolution.

There's an english translation of Syobon Action 2 with soundfix included somewhere on the internet. I have it on my craptop, but I do not currently have access to it.

>fun

You must be a masochist, this game is pure hard as hell. ;_;
The experience was made more bearable by the cheetahmen bgm though ironically.

But yeah, if you guys manage to port this, we can have more blood for the cat god.

 

[nop90]

I'm porting it because my boys asked me to play cat mario on 3ds.

I have a very difficoult porting project in progress and this is an easy exercise of mapping sdl to 3ds.

For japanese tezt, already used a teanslation available on internet.

The game is fully playable, it only miss sounds and needs resized image (now it resizes images using GPU while drawing them on the screen, result is not very good).

Ha, this looks great. I still play the DS version occasionally.

Hmm... Doesn't Syobon Action allow you to choose any level no matter what?

If not, it'd be nice anyways. And besides, the SMB1 ?-block graphics look a bit out of place in Syobon Action. Maybe replace the ?-block/level icons with just the level name>

 

[Khangaroo]

if it's based on open syobon action, change #define AUDIO_CHANNELS 4 to #define AUDIO_CHANNELS 2 for sound.

 

[TheCruel]

If you're scaling down using GPU, you need to use LINEAR rather than NEAREST.

You're right, but 3DS doesn't have the 0-9 keys to select the stage so I inserted a list of icon to select it. I also locked stages like it's on my daughter version on Android, but stages can be unlocked using L+R+Y (I like adding such stupid things )

And besides, the SMB1 ?-block graphics look a bit out of place in Syobon Action. Maybe replace the ?-block/level icons with just the level name>

I used the first icon found wth a serach on google. Maybe I'll change it later.

if it's based on open syobon action, change #define AUDIO_CHANNELS 4 to #define AUDIO_CHANNELS 2 for sound.

On 3ds there are 8 channels available, but the problem is that there is no SDL support so sound functions have to be coded from scratch.

If you're scaling down using GPU, you need to use LINEAR rather than NEAREST.

I'm using @xerpi 's sf2dlib that makes easy using fonts and have a good implementation of drawline that isn't natively available on the GPU. I think that sf2dlib uses NEAREST as default, but also LINEAR doesn't have a good result. The problem is that the icons are very small with tiny lines and pixels.

Next step is to add sound, I need to compile the OGG lib for 3DS and I'm not very good with makefiles. I'm trying to use the 3ds portlibs makefile as an example.

Better now?

I'd imagine all that needs to be fixed now are the graphics and the sound, correct? Awesome work!

 

[nop90]

Just added some sounds (only sound fx not background music).

Everything compiling and running on citra, but citra has no sound output do I have to wait tonight to test it on my 3ds.

awesome xD I actually finished this game on a wii port hha
