Hi gameblabla,

I noticed that save games are actually not working with scummvm on the nspire. I also just got your PM ( I do not log in when checking forums for activity so I rarely see them in time ).

Anyway you could try to change the following lines in \backends\fs\nspire\nspire-fs.h to
virtual bool exists() const;
virtual bool isReadable() const;
virtual bool isWritable() const;
like remove the function body after the const and implement them like so in \backends\fs\nspire\nspire-fs.cpp:
bool NspireFilesystemNode::exists() const {
Common::String str = _path;
if( !_isDirectory && !str.hasSuffix(".tns" ) )
{
str += ".tns";
}
return access(str.c_str(), F_OK) == 0;
}

bool NspireFilesystemNode::isReadable() const {
Common::String str = _path;
if( !_isDirectory && !str.hasSuffix(".tns" ) )
{
str += ".tns";
}
return access(str.c_str(), R_OK) == 0;
}

bool NspireFilesystemNode::isWritable() const {
Common::String str = _path;
if( !_isDirectory && !str.hasSuffix(".tns" ) )
{
str += ".tns";
}
return access(str.c_str(), W_OK) == 0;
}

The idea is that file access is wrapped in a way that scummvm does not know about the .tns suffix except on the lowest level because there appear to be many places in scummvm that expect a file to have a certain name or format.

Just a note, maybe you should distribute the patch or the full source with your binaries, or make them available elsewhere, to honor the GPL.

Just wonder, since I don't have the capability to load a game this size onto my calculator, but will Humongous Entertainment games work?


EDIT: I know some of the games run on different engines. To be specific I mean later ones like Spy fox or Pajama Sam

Ok, thanks.

Hello,

I noticed that critor still has problems loading saved games in ScummVM. gameblabla, are you sure that you build from the right source and did the .h and .cpp modifications ? It works here. You can test save games by pressing the '(' key on the nspire to save a game in scumm games and use the same menu to load one. I can provide a patch against the original 1.7.0 source on request if it still fails.

Hi gameblabla,

try this, please report back.

Hi gameblabla,
try this, please report back.

Hello rwill,
i compiled it again and the fix works just fine.
I could save and load a game in Lure without any trouble, thanks rwill.
I think you deserve all credits.
Anyways, i reuploded ScummVM with the patch inside.
Strangely enough though, i did not have to fix Dragon History for nspire this time.
Weird.

will Humongous Entertainment games work?

HE games should work actually on Nspire, i checked ScummVM's doc and they apparently only require
the standard ScummVM engine.

Now, i'm currently thinking how we can switch from SDL to n2DLib for the video.
Since rwill already switched timing and input to native, that's the only thing left to do.
It should be a simple matter of pointing the framebuffer to the buffer adress.
That's how i did it with PokéMini.

SDL version:
PokeMini_VideoBlit((void *)((uint8_t *)screen->pixels + PMOff), PixPitch);n2DLib version:
PokeMini_VideoBlit((void *)((uint8_t *)BUFF_BASE_ADDRESS + PMOff), PixPitch);
The only problem is ScummVM's abtrasction system, probably the reason rwill has not
switched to native yet.
I simply need to look at the other ports to get it though...

I FINALLY found the reason why my emulators were so slow :
Simply linking SDL to your executable, even if you do not use it, will slow it down twice as much !
I almost became crazy when i learned that...

I updated PocketSNES, Potator, Oswan to n2DLib and they are now 20% cooler 200% awesome !

I can finally run all my SNES games fullspeed on my overclocked TI Nspire CX (266 Mhz),
same for Potator emulator and Oswan is much faster. (still not fullspeed though)

I will do a second video about PocketSNES tomorrow but in the meantime,
you can download the new versions below.

And i'll try to work on ScummVM too, it's just a daunting task though...
