The PS1 has a coprocessor 2, it has extra instructions. The SDK tells
me:

Code: C  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i #define
gte_ldv0( r0 ) __asm__ volatile (                       \        "lwc2
  $0, 0( %0 );"                                   \        "lwc2   $1,
4( %0 )"                                    \        :               
                                      \        : "r"( r0 ) ) 
a) I'm not shure how to translate this
     the first operand is a register, the second is the parameter r0


b)
 1)
I added
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i A_LWC2to
./compiler/mips/opcode.inc
and
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i 'lwc2'to
./compiler/mips/strinst.inc

now he recodnizes the Instruction, is it enough? Pls help me with a)
because I don't knew how to do the operands the right way and when we
will see if the instruction has the correct implementation
