Hey guys, today while searching for and trying to get some ancient and abandoned Cave Story engines to run on dingux, I noticed this new one (dated 2010), called NXEngine.
After a couple of minutes I had it running on the Dingoo. It looks very complete and as the author claims: "Currently you can make it from start to all 3 endings and all the objects I know about are implemented". So it looks like a perfect engine for Cave Story on Dingux

Here's a short video showing the current state of NXEngine on Dingux:

<a href="https://web.archive.org/web/20210121132634/https://www.youtube.com/watch?v=dUFO48HiXhg" target="_blank">https://www.youtube.com/watch?v=dUFO48HiXhg</a>

There are 4 things I need to fix before I decide to release it though:
* music support causing game hiccups
* font quality in 320x240
* button mapping/key captions
* a way to convert the datafiles on dingux without a need to run the game on PC first

If anyone is willing to help me with the development of this game, he is welcome to do so. Dingux deserves a Cave Story port and I want it to be perfect

Huzzah!

Frabjous day! I was hoping Cave Story might one day be ported to the Dingoo.
Thanks, zear! Looking forward to its release.

The font is semi-fixed now. I replaced TTF_RenderText_Solid with TTF_RenderText_Shaded so it's anti-aliased now. The thing is TTF_RenderText_Shaded introduces a font background color and so far I haven't figured out how to make it transparent. This screenshot is a little trick where I set the font bg color to match the bg of the text box. But for all the other parts of the game where the background is of a different color it will not look good anymore

Here's how it looks like if I use a different background color:

I also improved the button mapping in the menus, but the button captions still need to be changed from F1, F2, ESC to A, B, SELECT etc. This is embedded into the datafiles, so I'll have to either extract and modify the bitmaps, or change the menus to text only.

You could try the TTF_RenderText_Blended, I think it's anti-aliased too and don't require bgcolor.

Tried it, but for some reason it resulted in white blocks instead of text

And if you use SDL_SetColorKey to force the transparency on the surface returned from TTF_RenderText_Shaded?

It should be something like this:

Code: [Select]

    Uint32 color = SDL_MapRGB(textSurface->format, r, g, b); 
    SDL_SetColorKey(textSurface, SDL_SRCCOLORKEY | SDL_RLEACCEL, color);

Could you use another font? This one is a little hard to read in low res screens :/
I have a sugestion...

If you're asking where to get the Cave Story build, you have to patiently wait till i release it

But if you're asking how to install dingux on a330, well.. browse the forums, there is a lot of threads about that already.

I was a little quiet recently, so here's a little update:

Thanks to the original author NXEngine supports bitmap fonts now:

Also, the exit dialog is now fixed:

The only problem left now is the music support..

I also made initial ports of NXEngine to GP2X and OpenPandora. The latter uses experimental widescreen support:

(full size)

Since I wrote a simple joystick support for gp2x, I am interested in supporting wiz and caanoo platforms as well. Because I don't have that devices, I'm gonna need some beta testers. Also, some info on what's the newest toolchain/libpack for that platforms would be welcome

Nice! This font looks so much better

Wiz beta tester here if needed. Should have my Caanoo in a couple weeks as well. One question though, why port this to GP2X? There's already Cave Story for that console. Does this diifer from the original?

Looks great!

Looking forward to the Dingoo release.

Awesome work, zear!
