Indeed, tired to await the hypothetical source of Yoshihiro which to me was promised so that I integrate a dynarec, I decided to only leave in the adventure.

How was born this adventure?

The starting point of my adventure, it was to propose a dynarec which could be carried out at least twice more quickly than the PSX could not make, by hoping that the remainder of the emulation will not exceed other half of the resources available: in short to allow to emulate the PSX in fullspeed. A chalenge, in fact.

Why I PCSX does not begin again?

It is simple, this source is absolutely not adapted for the PSP. It is not particularly optimized because it is written for GCV survitaminés in gigahertz which naturally manage realities of double precision double precisions. If you try to generate this code for the PSP, you will obtain a at the very least ineffective monstrous code because the PSP nativement does not manage the realities with double precision double precision - very much used in the GTE for example: the PSP will row in the plays of action 3D which make massive use of the GTE. Approximately, it is what you obtain with PSX-P.

What currently contains YAPSxP?

- The dynarec CORE0 (R3000AF) which will be declined in CORE1 then in CORE2, once the emulation of the GTE (in progress) and the entirely implemented COP0.

What will contain YAPSxP?

- The management of a standard pad (already written but not tested)
- The management of graphics (GPU, there I touch on the manner of proceeding)
- The management of the video (MDEC, lives the VFPU!)
- The management of the images (CDR, euh… that will not impassion me masses that…)

What is what YAPSxP will not contain, at least initially?

- savestates
- safeguards
- the sound (I do not despair to do it one day)
- in short, the remainder

Here are, the sources will not be LPG as I had envisaged at the beginning. I am in the active life thus one will not have to hope to see it turning completely for Christmas: he will not serve anything to ask for to me the date of a first release. I do not believe that PCSX was done in one month in the beginning. However that does not make a month that I begin this project, but the dynarec is in very good way and should promise not badly with the management of the GTE and COP0.

NOTE: if there are talented developers among you who would like to contribute on parts that I do not hope to implement for the first release, you can always contact me by PM.

NOTE2:
- CORE0, dynarec which is carried out like an interpreter, primarily for the need for Proof Of Concept and déboggage.

- CORE1, dynarec taking again the base of the CORE0 but by carrying out a block with as much as possible instructions generated in order to release sufficient resource CPU for the remainder to emulate. Already tested with happiness on a pre version.

- CORE2, dynarec with additional optimizations which will make it possible the emulator to be a little more “intelligent”.
