Thanks for the info, and I see. I think 256 for games on such small screen would be just fine enough anyway.

Also I just got a BSOD on my CX! O.O (well... not really, but the loading screen reminded me of one)

I've now added hardware 8 bpp on both TC (i.e. Touchpad/Clickpad) and CX models. In fact I restructured the code and there are now 5 different bpp modes: CX SW16 HW16, CX SW8 HW16, CX SW8 HW8, TC SW8 HW8, TC SW8 HW4 (where SWx HWy is software x bpp, hardware y bpp display).

I'm considering implementing double buffering and wondering if it's worth the trouble (in TC models it's unnecessary, no tearing thanks to the slow and shitty LCD). Also I need to fix some mouse issues and do some further fine-tuning before 0.2.0.

Could somebody with a CX do me a favor?

Could you grab the the attached file, send it to your calculator and just see if everything works. Move your finger around the touchpad to move the mouse, if you press it you should see "SDL_MOUSEBUTTONDOWN" showing up. It uses hardware 8 bpp and the touchpad, so I'd like to know if everything works nicely. Thanks for whoever helps me. :)

(0.2.0 is advancing nicely, there'll be a lot changes and a bigger "launch" than usually)

It works, but lags a lot. Sometimes the program completely freezes for a few seconds.
But is amazing, thanks!  :)

I tried it on a CX CAS (don't know if there's anything different than a normal CX) and i have the same result. I shows up, shows the coordinates, shows the mousebuttondown and coordinates, but lags sometimes for a short while

edit: My calc did a reboot when i pressed [esc] ö i don't think that' normal.. i treid it 3 times, and everytime it did a reboot..

Thanks a lot you both.

Not sure about the rebooting issue, but I fear it has something to do with the mouse, I had the same problem at first but thought I had fixed it (on Touchpad it works). When it comes to mouse lag, it's very weird behavior, but I remember having something like it on my Touchpad at first, fixed it by moving the touchpad scanning function a bit. Could you try the attached program for me? It reads raw values from the touchpad, I'd like if to know if the "Velocity" still lags and updates rarely or if it's fast:
Spoiler For Spoiler:
I can only bribe you with a thank you in the readme.

This is how the mouse works on my Touchpad:

The values change when I use the touchpad but the mouse doesn't appear.  :(

That's normal, I disabled the mouse so that I can only read raw values (no SDL involved except for the font drawing). So it seems it does update it normally. I think the problem might be similar to the one had some time ago. Thanks a lot, I'll look into it. :)

I'll give it a try when I have some time, but I have a bug to report for the Plasma program: After a few times running it, when you press enter to run the file, nothing happens at all, even if you ran another Ndless program before. Once your calc rebooted, it seems to work again.

Just to keep you guys updated, the mouse now works on CX models when using SDL_WaitEvent() (thanks atiatini for the testing), but it still "lags" (actually input lag) when using SDL_PollEvent(), so that among other things remains to be fixed.

Also meanwhile I've been working on an extremely simple image format for those who might prefer to include images in the executable (useful for small sprites and such), along with a converter:



Oh and I'll probably be a bit less active as I plunged into some more serious indie game development.

Nice, hopefully we will soon see awesome games (and emulators :)) being made with nSDL!  :D

And yes, there is a bug in the plasma demo, I'll probably release an updated version soon. ;)

EDIT: Here it is:

Some more updates...

I've added support for own extremely simple image format, and I added a SDL_nDrawStringInRect() function which draws a string within the boundaries of an SDL_Rect, as you could imagine. Here's a little screenshot showing off the NSP_FONT_AUTOSIZE feature (non-monospaced fonts), SDL_nDrawStringInRect() (the purple rectangle is only to show how it fits itself inside it, it's not part of the function), and an image included in the executable (everything is of course well integrated into SDL, the SDL_nLoadImage() function returns an SDL_Surface for example):



Here's also a more recent screenshot of the image converter that'll be included with nSDL 0.2.0:

Amazing!  :)
Just wondering, how's the performance of this compared to BMP blitting?

Should be exactly the same as the result is the same (SDL_Surface).
