http://www.geocities.jp/penta_cle5/psp.html

Mirad, segun e visto tienen un downgrader 2.0 a 1.5, ahora que sea verdad o no jeje.

Espero que no sea otro hilo de rumores o fakes.
Yo no tengo ni los caracteres instalados, por lo tanto me sale todo el rato "????????????????????" pero viendo ke se puede descargar el PBP Unpacker y tal, kizás ahi lo ke te explica es como extraer el firmware o algo así.
Os dejo la traduccion del Japones, yo no tengo ni idea de loq ue significa ni si es Fake o algo sabido, pero os lo dejo para que juzgueis. Un saludo;

First, however you analyze (it is not such an enormously potato, ^ ^; ) Hitting, it will gather the necessary software.
Note: That there is no update file (v1.50, v1.52), it does not become story. When it does not have, please receive from the friend.
Being said, that "please attach to me with the mail", the thing which you give being not to be possible, please acknowledge.


1. Necessary software
Stirlinghttp: //www.vector.co.jp/soft/win95/util/se079072.html
PBP Unpackerhttp: //pdc.me.uk/pbp/



2. Start of down grade methodological analysis!
Failing in beginning, in order to be all right, it be sure will copy the update file. You use below that.
First from intelligence of the ancestor, we have decided to try simply using 2 memory sticks (below MS).
With, being to think, it does, but already also the other person doing, it reaches ^ ^; Well on the air do, you write.
The rise data of v1.52, the rise data of v1.50 is inserted in another MS in MS.
First MS where v1.52 enters is inserted, the rise data is started. The logograph of PSP coming out, between the ‚é in another MS fast
It replaces. When it does...
It goes to the update picture, but there "already new version is installed," you question and crack.
After all it was useless. What is thought here, is that "2 time" version checks are done.
Resigning, it will try rewriting version.
PBP Unpacker is used. The update file of v1.52 will be opened with Open.
Please appoint the folder next with Extract. The file which to the list is output 4.
Please open PARAM.SFO next. When it does, it is the rise data! Don't you think? it is understood well.
Double please click the place, UPDATER_VER here. And 1.52 is rewritten to 1.50.
When well is, rewriting the part of TITLE, you are not concerned. (As for here just a little memory ambiguity ^ ^; )
Selecting Save to of BasicOptions, File you push Save. Something after coming out hard, PARAM.SFO dialogue of retention
So it increases. Please retain favorite in the place.
Next, please select New. The file which first is output to the place of the corresponding file, respectively is selected.
Please select the file of the one which is rewritten in PARAM.SFO. Other than that that way hugely will not, increase it is.
Selecting Save, it retains. The impersonator was possible with this.
It will try inserting this "impersonator" in MS. When you try seeing with PSP, when TITLE is rewritten, that is indicated.
It will try starting. How probably will be? Be able to start safely even with MS one, the better seed.
After this... it was useless.
As a result as for being understood, as for first check at only numerical value of version of the file which houses information simply checking
It is. And it has repelled with the version information which reads out from the data division of the file in 2nd check, we would like to see, is.
With so the file inserts after the 2nd check and should have substituted? With to think, starting the rise data of v1.52
Being the place where it goes to the rise data picture, it tried replacing MS. The instant which it pulled out, you got angry, ^ ^;

It will try using Stirling.
It will try opening among DATA.PSP the files which are output to 4. Also the rise data of v1.50 outputs four files in the same way,
Please open also DATA.PSP of v1.50.
ƒEƒBƒ“ƒg of the menu DOTDT ƒE -> arranging into the top and bottom, it selects indication, next search movement -> selects comparison.
The question to which size is different it cracks, but please do not make the air. Pushing OK, when it does for a while, the result is produced.
Please insert check in emphasis indication and the synchronizer scroll. As for difference place summary without closing, the scroll doing the page
Please try watching. Almost, it is deep-red, the white place where, but here and there it is the place where the data is equal.
Something it is doubtful, don't you think?. It meaning that may be a hint here, it does, but...

By your are the limit to here. Lastly the book it is and solves one thought. (As for executing being to be difficult ^ ^; )
From the result may be a hole still in method of MS replacement, is. There is a switch which checks the taking out and putting in MS we would like to see
Being to be, if outside it changes two MS without taking out and putting in MS it produces the circuit, after doing to the update picture,
Is not to be possible to make the old rise data start by the fact that it changes to another MS, probably will be?



2005 August 18th postscript
You discovered anew, w
The person who has known already will be, but Imai there is no relationship. By his is yourself, ^ ^
With it keeps writing suitably with the notion that where you say. Perhaps in the future it keeps appending.


With DATA.PSP of the file which divides with PBP Unpacker, the common point of the rise data part was found.
Calling part, it is w which is part absurdly but being even to be a little good it does. If individual even a little various person does
Very, because it becomes something which has meaning don't you think?. With saying, the letter income ^ ^;
It is this subject. Below is the portion of DATA.PSP of v2.00.

Please look at the place where color has reversed.It is50andA0. Firstsubtractionpleasetrydoing 50 from A0.
Of course opening the portable calculator, it selects hexadecimal. Don't you think?the resultis 50.
Next, subtraction please try doing the part of the same address in the same way even with the other update file. After all the resultis50.
Obtaining? Just the file of v1.50 the ‚Á ‚Ä which is different? Please see carefully. Are lower two-digit how?There is no 50?
It is trivial thing, but doing at first glance, the file may be different, there was a common point to such a place. The one step it got near with this, ^ ^ (lie)
"Just v1.50 there is no excessiveness doing?" that perhaps, the person who thinks it is, but never there is no such a thing. If it tries making the computer, as for hexadecimal number
Calculation and the like being to be easy, it is recognized sufficiently as the common point.

To end it makes you read and the ‚å ‚Ú is and it is the result and m (_ _) m where it is not
Not just the amateur as for analysis being it is difficult w which is done
It is digression, but it binds and in v2.00 the ‚¿‚á oral ‚á it is to freeze and it does, but... is this specification?
Hola, por lo que creo entender, lo que hace eso, es abrir el update 1.5 modificarlo a otro numero, para que la psp, al comprobar version instale esa... lo he leido por encima, asi q tp se si es asi... no seria nada descabellado... Saludos
eso es una de las ideas q tenia yo
en algun momento el Firm al actualizarse debe comprobar uqe la version sea superior a la actual.

En esa instruccion se podria cambiar la variable que contiene la version de la PSP o la version del firm a meter ;)
Es lo ke os he comentado yo 3 posts mas abajo ¬¬
en ningun momento haces referencia a la pagina ni que sea japo ni na ;;)
Venga si, amos abrir 400 hilos sobre el Downgrader y su prima.

Todo lo que sea sobre Downgrader postearlas en el hilo de 200 y pico paginas, consideremos ese hilo como el oficial hasta que sigan los rumores y demás pajas mentales.
