All,

Please find (link below, PSP dev totorials section) a new PSP development tutorial concerning modules and PRXs, written by yours truly. There are a few rough edges and some parts are being fixed / completed / clarified. Many thanks to the reviewers for their insighful comments.

http://ps2dev.org/psp/Tutorials/PSP_Modules,_Exports,_Imports_and_Patches.download

Comments, suggestions or fixes are welcome. I hope this can be helpful.

Thanks :o)

Ani.

i don't think prxtool uses the new register naming but it can display registers as r0-r31 at last. Don't forget that prxtools was coded with no assumption about the right name on registers.

In fact, using $4-$11 or a0-a3,t0-t3 or a0-a7 or r4-r11 doesn't make any change. What is important is to know that there is trully up to 8 argument registers for a function.

prxtool disasm was written to the register model I use which uses t0 to t3 mnemonics instead of a4 to a7 and realistically that is how the toolchain maps them and I dont think the PSP uses the _new_ ABI anyway ;)

Admittedly you can switch prxtool to disasm the registers in the format 'rN' if you cant stand arbitrary mnemonics :) ('--disopts r' if I recall).

Hi.

I have a one question.
In page 6 you give a small example. I try to compile it, but there is some error. btw. You don't give source code to makefile and exports.exp. So I add from makefile and exports from PSPSDK - \psp\sdk\samples\prx\testprx:
makefile

SP_O_CREAT should be PSP_O_CREAT, simple typo in the tutorial that you duplicated.

some typos

page 13
... Assembler dump of the server.prx module
should be ...Assembler dump of the supervisor.prx module

page 08
... The following table shows the most common instruction mnemonics. It MIPS assembly, the result of
should be ...The following table shows the most common instruction mnemonics. In MIPS assembly, the result of

page 08 (Instruction table)
... lw rd offset(base) load the word at address into rd
... w rd load word at addr offset+base into rd
should be ...
... lw rd address load the word at address into rd
... w rd offset(base) load word at addr offset+base into rd

page 20
... you can use the sceKernelGetModuleIdList fuction,
should be ... you can use the sceKernelGetModuleIdList function,

page 27
... // offset to the "jla supervisor_0xB2C390CB", compute the
should be ... // offset to the "jal supervisor_0xB2C390CB", compute the

in all was decent read ...you must improve your grammatical skills
and use the comma (' , ') more properly :P as this is most common error

ex. Jack who loves to deny others of goods is one big asshole
is incorrect in grammar for the reason of improper comma usage
correct form is:
Jack, who loves to deny others of goods, is one big asshole

simple i know but you do this error many times ...i do not aspire to be a
grammatical cop, but if you, a aspiring writer, would def need to know
just exactly what can improve your writing
