Just anyway the psp is better.

it's impossible because the ds is dual core, baby :D

For vcmp.s EZ,S000 with S000 == 2 it returns 0xE I think it's good, but form same values with vcmp.q NZ,R000 it returns 0x3F, why?

EDIT :

OK solved, i didnt initialize the matrix OMG it happens :)

Another question now on vcmp.* and VFPU_CC, I have this code a = 1; b = 0; __asm volatile ( "mtv %1,S000\n" "vcmp.s NZ,S000\n" "mfvc %0,$131\n" : "=r"(i) : "r"(a), "r"(b&#4...

Thanks again you are very patient :)

I have another question but for vcmp f1,rs which are the conditions?
Can you help me, please?

thanks I found it but your site is very confused ;)

Again :) where can I find all VFPU opcodes? And their funcs?

yes now it works with aligned and unaligned memory. OMG now it works also with O2.

may be but form main.s (the asm file from gcc) #APP mtv $3, S000 mtv $4, S001 mtv $3, S002 mtv $4, S003 mtv $3, S010 mtv $4, S011 mtv $3, S012 mtv $4, S013 mtv $3, S020 mtv $4, S021 mtv $3, S022 mtv $4, S023 mtv $3, S030 mtv $4, S031 mtv $3, S032 mtv $4, S033 usv.q C000,0($2) usv.q C...

I dont know but if i write this it doesnt work, float mtx[2000],*pf; pf = mtx; __asm volatile( "usv.q C000,%0\n" "usv.q C010,16+%0\n" "usv.q C020,32+%0\n" "usv.q C030,48+%0\n" : "=m"(pf) : "...

it doesnt work, with aligned and unligned memory.

I tried qith this examples but it shows only zero, why? Can you help me? float f,*pf,a,b,mtx[132]; unsigned int i,i1; pspDebugScreenSetBackColor(0); pspDebugScreenSetTextColor(0xFFFFFFFF); pspDebugScreenInit(); i = (int)...

Where is the module pspdecrypt.prx?

ok thanks again, I have another question with this ASM instruction vadd.p R100, R000, R020 it puts the sum in the matrix 1 from matrix 0 but which are registers used? 100 = 000+020 110 = 010+030 |000|001|002|003| |100|101|102|103| |010|011|012|013| |110|111|112|113| |020|021|022|023| |120|121|122|12...

Thanks for help, but where? SVN? It doenst work.
But for VFPU opcodes that uses the matrices is it the first value?

you can use my emu http://actarus1000.googlepages.com/actarushomepage

I think you must work hard. Good Luck

yes umd emulation is very hard. I must have 2 pc for debug, now i must purchase.

cool :( i must

OMG what it happens? How can i decrypt the eboot.bin in my emulator?
Where is the source code. OMG again I cant understand.

* * * EDIT * _ * i can release the source code of my emulator if you want.

decrypt? how?

Hi all

Im working on my emulator and Im loading a commercial rom. In the file ISO I found 2 binary file BOOT.BIN and EBOOT.BIN. What are they?
Waht my emulator must load?

Thanks all for answers.

Sorry now im busy with emulator and I cant work on Linux in the next future...

1) Im using an interpreter, it's incomplete now :)

2) static set of emulated SCE and they are ... :)

Today there is a link, all suggestion are important, thanks

:) yes Im very corious and I want know the I/O port for better emualtions. But now Im using the HLE, there arent info on hardware.

Here's a new emulator for PC, Sam. Now it runs some pspsdk examples and I need of infos on hardware I/O ports. I hope in you.

Hi all

Does the psp support the multitextures? Or is it only a mipmap level?
