[Tutorial]Use the SNES9X for DINGUX on CAANOO

/* ===================================(caanoo.h) */

- First we create a new file to add the CAANOO Key-mapping.
- Filename: "caanoo.h"

Code: 
/*
	Caanoo Keys
*/

#define CAANOO_BUTTON_A             0
#define CAANOO_BUTTON_X             1
#define CAANOO_BUTTON_B             2
#define CAANOO_BUTTON_Y             3
#define CAANOO_BUTTON_L             4
#define CAANOO_BUTTON_R             5
#define CAANOO_BUTTON_START         6
#define CAANOO_BUTTON_SELECT        9
#define CAANOO_BUTTON_UP            11
#define CAANOO_BUTTON_DOWN          12
#define CAANOO_BUTTON_LEFT          13
#define CAANOO_BUTTON_RIGHT         14

/* =================================== */

/* ===================================(keydef.h) */

- Now we Change the keydef.h

Replace:
Code: 
#define A_1 0
#define B_1 1
#define X_1 2
#define Y_1 3
#define L_1 4
#define R_1 5
#define A_2 6
#define B_2 7
#define X_2 8
#define Y_2 9
#define L_2 10
#define R_2 11
#define START_1 12
#define SELECT_1 13
#define START_2 14
#define SELECT_2 15
#define UP_1 16
#define DOWN_1 17
#define LEFT_1 18
#define RIGHT_1 19
#define UP_2 20
#define DOWN_2 21
#define LEFT_2 22
#define RIGHT_2 23
#define LU_2 24
#define LD_2 25
#define RU_2 26
#define RD_2 27

#define ACCEL 50
#define QUIT 51
#define HELP 52

#define SHIFTL 30
#define SHIFTR 31
#define CTRLL 32
#define CTRLR 33
with:
Code: 
#define A_1 0
#define X_1 1
#define B_1 2
#define Y_1 3
#define L_1 4
#define R_1 5
#define START_1 6
#define SELECT_1 9
#define UP_1 11
#define DOWN_1 12
#define LEFT_1 13
#define RIGHT_1 14

#define ACCEL 50
#define QUIT 51
#define HELP 52

#define SHIFTL 30
#define SHIFTR 31
#define CTRLL 32
#define CTRLR 33

/* =================================== */

/* ===================================(unix.cpp) */

- Now we edit the Header Files.

Replace:
Code: 
#include "dingoo.h"
with
Code: 
#include "caanoo.h"

- Find the: "keyssnes" and we change the KEY SNES to Joystick SNES

Replace:
Code: 
uint8 *keyssnes;
with
Code: 
SDL_Joystick* keyssnes;

- Now go to S9xInitInputDevices and replace her this

Replace:
Code: 
void S9xInitInputDevices () {
	memset(sfc_key, 0, 256);
	sfc_key[QUIT] = SDLK_a;

	sfc_key[A_1] = DINGOO_BUTTON_A;

			else if (i == 16) sfc_key[RD_2] = atoi(envp);
			envp = j + 1;
			++i;
		} while(j);
	}
}
with:
Code: 
void S9xInitInputDevices () {
	memset(sfc_key, 0, 256);
	sfc_key[QUIT] = SDLK_a;
	sfc_key[A_1] = CAANOO_BUTTON_A;

}

- Now

/* =================================== */

/* ===================================(svga.cpp) */

- Now we edit the Header Files.

Replace:
Code: 
#include "dingoo.h"
with
Code: 
#include "caanoo.h"

- Find the: "keyssnes" and we change the KEY SNES to Joystick SNES

Replace:
Code: 
extern uint8 *keyssnes;
with
Code: 
extern SDL_Joystick* keyssnes;

Find: S9xInitDisplay

- In S9xInitDisplay find the SDL_INIT

Replace:
Code: 
if (SDL_Init(SDL_INIT_VIDEO|(Settings.NextAPUEnabled ? SDL_INIT_AUDIO : 0)) < 0 ) {
with
Code: 
if (SDL_Init(SDL_INIT_VIDEO|SDL_INIT_JOYSTICK|(Settings.NextAPUEnabled ? SDL_INIT_AUDIO : 0)) < 0 ) {

- Now go some lines down

Replace:
Code: 
keyssnes = SDL_GetKeyState(NULL);
with
Code: 
keyssnes = SDL_JoystickOpen(0);

/* =================================== */

- So now we Have an simple SNES for CAANOO thats works fine

Download:
Binary
Source

Have FUN, Rikku2000
 
Hello,

Thanks for the tuto. Really good starting point to port snes9x.

But, which sources did you use?
I tried your method with both source packs I found for dingoo on openhandhelds, replacing compiler and libraries in the Makefile.
I tweaked it in many ways. I didn't manage to get it compiled.
Did I miss something?

Can you add an example of makefile you used to get a "simple SNES that works fine for CAANOO" or a link to the right sources to use?

The file that seems to trigger most compile errors is getset.h.
 
Great! Thanks for adding the sources, and the binary.

I will try it.

Thanks again for sharing your work.
 
thanks, I had a little play with donkey kong country and seems to run smooth but when I got to the bonus stage it freezed up on me.
Looking forward to the full port for the caanoo :)
 
I just tried the alpha, got Super Metroid to run. :)
But I noticed you made Caanoo A = SNES A, the controls need to be like this.

SNES A = B
SNES B = X
SNES X = Y
SNES Y = A

Screw the labels, the button positions are more important.
Luckily Super Metroid has configurable controls.

Edit: Start is also mapped to the wrong button, II is select but Home is Start, why?
It should be I for Start, II for select, and Home for the emulator menu.
 
Hi,

I have a problem with the binary files.
When i execute them from the caanoo, it display please press select + x.
then i can't continue, event if i press on all keys, is it a bug ?

It's ok for me i changed the game (and gpe files), and after the game started.

omg this is not for using this is just en tutorial the snes works but better wait for a better version...
 
i just download the snes binary. i created a .ini file. after that i load the snes emulator, and secret of mana load and no buttons are working.

where is the rom launcher ? why the buttons dont work ?


thanks for answer. i went here because i dont see the snes emu in the download section

I think this was ment more as a tutorial and not a full port !!! You can easily change things yourselve if they are not emulation specific...
