Module0 - 2008 03 27 - For Cemu 1.3.4X Series

[seaboard18]

Here is the current patch that works for testing the current streamed algo 40 mecm.

If you would like to test this patch, recompile the source code for Cemu 1.3.4X Series



{ // module 0 for b*v and d*sh 20080327 (submodules II)
switch ((A00[0]>>5)&3) {
case 0:
{
unsigned char *bbd=&hw[0x1B], r[32];
int i,j,v,c=0x7279;
memset(r,0,32);
for(i=0; i<16; i++) {
c=0;
for(j=0; j<16; j++) {v=((bbd[i]*bbd[j])+r[i+j]+c);r[i+j]=v&0xFF; c=v>>8;}
r[i+16]=c;
}
memcpy(bbd,&r[16],16);
}
break;
case 1:
{
unsigned char b[0x11];
for (int i=0;i<0x11;i++) b[i]=hw[0x13+0x10-i];
hw[0x29]=hw[0x4D]=(memcmp(b,&b[1],0x10)>0)?1:0;
}
break;
case 2:
{
memcpy(&hw[0x1F],&hw[0x27],8);
}
break;
case 3:

{
unsigned char *bc1=&hw[0x1F], r[32];
int i,j,v,c=0xFB,c2=0;
memset(r,0,32);
for(i=0; i<16; i++) {
c=0;
for(j=0; j<16; j++) {v=((bc1[i]*bc1[j])+r[i+j]+c);r[i+j]=v&0xFF; c=v>>8;}
r[i+16]=c;v=r[i]+bc1[i]+c2;r[i]=v&0xFF;c2=v>>8;
}
memcpy(bc1,&r[0],16);
}

default:
printf("unknown submodule\n");
break;
}
}

Is this new? I didn't think we needed a module update.

Thanks seaboard.

this must be for bev

Both providers use the same counter measures most of the time now. A fix for one provider should work for the other as well now days. Not sure this is a good idea for them to follow each other so closely or not, but they do.

I asked if this was new because cemu is still running on both providers as far as I know.

Its only considered new if cemu was not working. The provider dropped the algo00, where anything would work and went back to map calls now. For those who had this cemu compiled prevesly then it would still work seem less.. you would have not noticed the change.

Actually, this module0 is very slightly different than what I had, but hey, the important thing is that things are working. Thanks for keeping us updated seaboard.
