[Orion_]

hi
just wanted to know what number/adress correspond to: _ISR_STARTADDRESS ?
thanks

...and from where did you pick up this define?

#define _ISR_STARTADDRESS (0x0c7ac000)

...and from where did you pick up this define?

from gpstdio_internal.h/.c from darkfader
I wanted to try reading the GP32 ID to make a beta-tester protection
then only the beta-tester who have the autorisation of testing a game can run it just by verificating the GP32 ID, it allow to avoid some problems like ThunderZ with his NeoGeo emulator

but it seems that it doesn't work properly

funny.. I can't find them (define & files) being part of any SDK.. anyways reading GP32 ID goes nicely via SWI 0x105..

"anyways reading GP32 ID goes nicely via SWI 0x105.."
I know but this doesn't work (or maybe i'm too stupid to make it work :unsure: )

Digging some old sources...


getID:
stmdb sp!, {r1, r2, r3, lr}
mov r3, #0 @ 0x0
swi 0x00000105
ldmia sp!, {r1, r2, r3, pc}


....

char bufid[4096;]
char buf[33];

if (getID(16,16,bufid) != 0) {
GpTextOut(NULL,&gpDraw,0,20,"Error! Failed to read DEV ID",0x00);
} else {
char key[8] = {"SANGHYUK"};
buf[32] = '\0';

for (n = 0; n < 16; n++) {
gm_sprintf(buf+2*n,"%02X",bufid[n] ^ key[n % 8]);
}
GpTextOut(NULL,&gpDraw,0,30,buf,0x00);
}


...should do the trick.. :blink:

thanks a lot, it works perfectly
