New Code Contribution

GoDE:
Yeah, I noticed some of those bugs myself :-( I'll be looking into those.

I'm also checking out the possibility to using the psp's ME for hw decoding instead, hopefully allowing the MapThis to get most of the system resources (and lower CPU for longer battery time).

Thx for the feedback, much appreciated!

It's nice to see that more and more people are playing with the code :-)
hw decoding is definitely the way to go, but so far it seems to work funcky under different firmwares/psp boards...
Modular design may be a way to go: you should be able to load a custom prx (for example mp3 plugin) and just use the methods, defined in it..
(much like those usbacc.prx / usbgps.prx files, used for navigation)
This way people may be able to use mp3 plugin version, that runs on their psp/fw and at the same time use your interface..
Just an idea, but should not be hard to code/test..

I think that it is a good idea and my C is coming all back to me know :-)
So I should be able to create an prx and allow other coders the port that prx to other firmwares. However I better focus getting own code work properly....

Status:
I've also replace the software (libmad) mp3 decoder with the a hardware mp3 decoding now. Seems to work pretty well and Mapthis runs as smooth as before :-)

However the hw mp3 player seems to crash at random intervalls, need to sort this out.

Hopefully I can have a new test version out this weekend.

Cheers!

wow! MapThis don't stop growing!
every time a come here there are some improvements!

i'll try last GoDe's eboot, thanks for compile it to holux version and thanks to Nieko too.

GoDe: i'll love to try fxpsp version too

it seems to be nice too, and if you compile all the functions, that willl be greater

Thanks you all and speciay deniska

I have the compiled version but yesterday i cant' upload it to the server (he looks very busy).
Let me try again.

It would be nice if Mapthis was a bit CPU friendlier. I talked with Nieko on this.

You see, the Nintendo DS GPS program works on that system really fine. The Nintendo DS only has a 67 mhz ARM processor.

Mapthis uses the 333 mhz processor of the psp and it eats it all up.

I've also noticed that there is a bug/feature that the 3d mode of the maps require a LOT of cpu power.

I managed to get Mapthis fullscreen with RemoteJoySDL.

Framerate drops from 30 FPS to only 14 while 3D mode is set.

It would also be nice if Mapthis can record your own voice prompts. A sort of calibration with the Chotto Shot mic or something.

So mapthis says: "What do you want for prompt left ?"
And then you speak: Turn left here.
It records it and saves it in mp3 format (with hardware encoder) as a prompt for mapthis

Another feature is that mapthis will still work as usb is engaged.

Now if you have plugged in USBHOSTFS or simple usb 2 pc connection, and you start mapthis it says (on psp-290 version, maybe also on generic) GPS is not working, because USB is now working.

Maybe USB and GPS could work alongside eachother.

Last feature i would suggest is a triptimer and summary. So i can see how many miles i've driven last month, year or so. With a press of a button you can recall a certain drive (see Nieko's example of GPS recording to a trace with POI points).

Here is it !
You can identify it on the "MP3" in the Game Picture.

I am actually re-writing most of the blitting routines to be more efficient, so expect much better rendering performance in the next version...
I already re-wrote lines implementation to allow transparency, did rotating POI icons (so they never upside - down). etc..

Very nice !
Are you implementing that vector map idea in the new version or do you drop it ?

Because Nieko said that vector data can be extracted from the open-source openstreetmap data.

Thanks GoDE!!! I will try it!!!

with the other eboot (the last one before this) the autozoom fuction is great! i hope deniska include that in next version

but i missed the power control

deniska: that is a very good notice! :thumbup:
the 3d mode is great but... you know

...and it's great too and probably simple to you if you implement an extended zoom for the other modes, specially for north mode, something like 0.5x or 0.75x

about the vector thing... i live in europe
