Dingoo A320 forum

The best game for test the Y/B problem is Megaman X : frst level, first second, you just have to charge the blaster (press Y for a couple of seconds) and jump.

My black Dingoo that I got yesterday still has the Y/B issue.

Are you sure? Can you be holding a shell with Y and jump without letting it go?

I was holding a shell and running with it. I just tried it with the jump and I let it go. I thoought I had something here. Oh well, I reassigned my buttons. The A and B sure feels more natural than the Y and B for Mario, for sme reason. I am going to have to get Mario out and stick him in the old SNES that I have hooked up in the living room.

if mario is kind enough to come to your house, you should not mistreat him in such a way.

i created a little application to show me which button i pressed on the screen (to figure out the button values and to see if they are correctly mapped) and you can cleary see what's happening

the dingoo doesn't register the Y Button when B is being held down, and when Y is being held down and you press B, Y gets released. I'm wondering though if it really can be solved with a firmware update, why hasn't one been released already , it's just a thought though.

if anyone is intrested here's what i changed to get ahold of all button presses on the dingoo A320 :

Code: Select all

extern "C" void kbd_get_status(KEY_STATUS* ks);
//These are the actual button values
#define SKEY_UP 0x00100000
#define SKEY_DOWN   0x08000000
#define SKEY_RIGHT   0x00040000
#define SKEY_LEFT 0x10000000
#define SKEY_A 0x80000000
#define SKEY_B 0x00200000
#define SKEY_Y 0x00000040
#define SKEY_X 0x00010000
#define SKEY_L 0x00000100
#define SKEY_R 0x20000000
#define SKEY_SELECT 0x00000400
#define SKEY_START 0x00000800
#define SKEY_POWER 0x00000080

//changes to the onkey function to make use of all the buttons on the dingo a320
extern "C" void onkey( Engine* pEng )

so when using the S2D Engine's input functions
A = KEY_1
B = KEY_2
C = KEY_3
etc

First of all, thank you very much joyrider, this would surely be in good use.

IF it is like it seems, to be a hardware (or OS?) error, it would seem to be a hard nut to crack.

Could anyone please clarify IF this would be possible to solve with a firmware, and how? I would be really disappointed if it was discovered that a firmware fix was impossible after all .

Still we got good emulation possibilitiess for NES/GBC/GB/GBA/SMD/SMS/SGG etc (all not complete but could function with the button issue), but I'd sure miss the snes-emulator (and any further possibilities of a better snes emulator) !

I believe booboo tested it out on his linux build, or at least looked at the schematics and/or gpio assignments in the kernel, and it appears to be just a software issue. This should be able to be fixed in a release from dingoo, or in linux.

Aaah, I hope it is so, thank you !
