Sorry, my choice of words was a mistake. I did not mean to imply that it scans the complete subdirectory tree. It scans every child directory of the current directory before letting you click-on and proceed to the next subdirectory.
Thus, for me, opening a new game involves
I don't know hildon, but looking at libhildonfm2-dev_1%3a1.9.49_all.deb, it seems possible:
in hildon-fm1-compat.h
in file hildon-file-chooser-dialog.h
http://library.gnome.org/devel/gtk/u...leChooser.html
Additionally, when selecting a game, it is impossible to differentiate between the actual game, the save file (.sav) and the state file (.sta) without comparing the file creation dates because the browser only shows fifteen (!) characters of the filename (on an 800x480 screen, this is quite an 'accomplishment'). So it would be helpful if you could set "open File" to only show .gba (or supported compressed file types) in the chooser, or alternately put save and state data in a subdirectory of the game dir.
Performance
-------------
Very impressive speed ...
However, it is possible to scale 3x in hardware (GBA 240x160 to Nokia 720x480) without speed penalty. This is normally exposed via Xsp extensions ('pixel doubling'), but ssvb (Siarhei Siamashka) sets an arbitrary screen resolution in mplayer using ioctls.
See the mplayer svn for implementation details.
Some useful information can also be found here:

Again, thanks for the great emulator.

Thus, for me, opening a new game involves
Click VGBA MaemoTo reduce most of these steps, remember last directory accessed (store to ~/.vgba or gconf?)
Click 'Open file'
Scroll left window down to 'removable memorycard'
Click 'Removable memory card'
...Wait ~3 seconds
Click 'games'
...Wait ~10 seconds
Click 'console'
...Wait ~5 seconds
Click 'GBA'
Scroll right window down to the game of choice,
(right window shows only three (!) files at a time)
I don't know hildon, but looking at libhildonfm2-dev_1%3a1.9.49_all.deb, it seems possible:
in hildon-fm1-compat.h
gboolean hildon_file_selection_set_current_folder (HildonFileSelection *self, const GtkFilePath *folder, GError **error);
GtkFilePath * hildon_file_selection_get_current_folder (HildonFileSelection *self);
in file hildon-file-chooser-dialog.h
GtkWidget *hildon_file_chooser_dialog_new_with_properties(Gt kWindow * parent, const gchar * first_property, ...);One of the .h files references the gtk file chooser help page

In fact, I can just write a piece of assembly code that does x3 scaling, same as I have done with other scales. may be a bit slower, but will cause less interference with other applications.
The emulator seems to run 20+ fps at least for some games; This is near the limit of lcd controller bandwidth at 720x480 @ 16bpp. Since vgba is almost (not quite) able to play sound without stuttering, I think improving speed would be preferable to degrading speed. 3x scaling requires 9x the memory transfer of 1x and may impact cache negatively.
Now i have to add that I haven't had time to figure out how to do this myself. So I probably should code more and post less.

What strikes me most is that the emulator is working on 770 with OS2008HE too! Not only that, but without sound and with scanlines is close to the speed of N800! And thats with a 32MB ROM file
So, another use for your old 770 - turn it to a GBA
Thank you fms!
EDIT: This means you didn't even use processor specific optimization...

Should we do a new thread reporting which games work ?
Im tempted!

F-Zero works very well. Very fast, but it eats cpu. The small xkbd keyboard works ok. Anyone try the dosbox versions that cover the right or left side of screen. Here is a suggestion for a developer, can someone make a small on screen joystick with left/right, accelerate/decelerate, front/back, etc... buttons. Dan
What about replacing with the standard GTK file browser which I see when apps are not hildonised.
(BTW: I cannot develop so I am talking utter rubbish please ignore me)
