Yes, you are right AudioMonster. It could also be possible small unit doing "heavy" data processing which are reconfigurable in terme of connection... But then you would need a kind of "main cpu" to control the flow (take data here, move it there...), which does not match the spe...

Hi I dont think ARM has anything to do with the VME, it does not match any of the description done before in term of energy, power, feature. A mips or ARM cpu is quite expensive in term of electrical power for a given output. But it is versatile... Which is the opposite of the VME. I heard also abou...

Hi, I am actually playing with FPGA on my free time... And what you are describing about "reconfigurable DSP" sound fairly like a FPGA to me but it could be also simply the "assembly program for a DSP". But reading about power consumption and feature, it seems like an hybrid betw...

Hi,

Yoyo, thunder and I have released finally our porting of V1.39 of Snes9X.
Main point is hardware accelerated rendering.

See you.

Yoyofr, it seems that we have been caught and we have a winner here :)

Hello, I definitely agree with everybody on the subjects. :-) 1/ Mr brown, I am not against the way you lock the threads. Actually... I would be even more tough than that ! :-P People release link to warez would be banned RIGHT AWAY. (shoot the guy, not the pixel... :) But stuff like "people do...

Hum... I admit that I may have went too far. Still, stuff like it's usually brought about by folks who aren't actually developing anything for the PSP. *Ahem* is very nice... You can not avoid to talk to somebody without trying to provocate him, do you ? That is EXACTLY what I was talking about beei...

Hello, 1/ Sorry for disturbing with something that seems off-topic. (to you at least) But it is an important matter to me, and it will benefit the whole community. Some people do it (modify the flash) knowing that they do it, but malware could exist. I believe that it is NOT off-topic but closely re...

I believe that : - Appli modifying the flash should warn the user at run time with a dialog like : Are you fully understanding that... bla bla bla YES / NO. - Homebrew appli should be packaged with a standard I/O module that filter the access to the IO at run time and use this module instead of dire...

> konfig I precompute nothing... What you do is compute the coordinate screen -> texture for the first pixel at the beginning of each scanline (this could be optimized too actually),and then use the inverse matrix to find the next pixel inside the texture when I move on pixel on the next right pixel...

konfig> background size is 256*224 in pixel, each multiplied by a 2*2 matrix(6 floating point operations), also processed at 60 fps, that is about 20m flops. Its seems you really know what you are talking about right ? Try to do something smarter than a matrix computation per pixel. Floating point o...

333 Mhz if you go full soft is a challenge. No the versions that are outhere for the moment do not use the hard, plz look around and logically deduct that nobody knows how to use the 3D on the PSP yet. Now even if we could do it (hardware acceleration) -> fine. But how about : - mode 7 (you can rota...

Hi guys, I am not sure if this thread need to turn into a snes emu development thread :-) I bet its the wrong place to do so > Any admin. plz. correct me if I am wrong. Anyway, if people are interested to tune this stuff, or they join the project and we tell them what to are the part to do inside th...

To be honest, I would rather see people use lower clockrates (or lowest possible for each software) and learn how to better optimize their code. Hum... Running a snes at full speed with copro on a 333 mhz is a challenge I think. (sound stereo 48 Khz :-P, no frame skip) Try to emulate the ARM cpu at...

Hi numchuckskills,

If you are so frustrated, may be you can help us to optimize it ?
We are 4 people working on such project now...

Actually if someone is interest in optimizing Snes9x, please ask me.

Regards.

Kemical... I think a lot of people here are waiting from you to fully test if you can bring back your PSP to live here or not. And if it is really due to a 333Mhz overclock. By spreading wrong information, a lot of people are afraid or wait to use a feature that is may be doing NO DAMAGE whatsoever ...

I think there is a big difference between running a sequence of MIPS instructions and simulating two MIPS cores, floating point units, a vector unit, etc... and the buses that connect them all. Hi ! Sorry, I may have missed a point :-(. So you want to simulate the mips core and everything ?(=Simula...

Hello... I am sorry but I dont see a difference with your emulator and PSPE. (And I have written some basic compiler, emulator and virtual machine so I know what I am talking about) Even simulator are most likely to simulate CPU the complete timing and hardware stuff of the cpu. I am not sure that P...

Hey weak, You could improve the quality of the screenshots by using 32 items lookup table and promote each 5 bit component into 8 bit correctly (normalize) : For the moment your whites are not white :-P To create the table, just do (n*255)/31 for each value between 0 and 31. Still quite usefull anyw...

Hi, The PSP is far more public than a console like the GP32. It is true that in the case of the GP32 you could damage your hardware. If a setup of the clock speed would have been dangerous for the hardware, Sony would not have authorized such API at first. I believe so. It is not overclocking :-). E...

Hum... I am not sure that the console run at full speed (333) by default. (even 222) If you take the GP32, it can go up to 133 or 166 but it start at 66 mhz. Considering the battery energy as wealth, you care about it and you dont want to waste it. I think it is really to the game to handle it : lik...

Hi, Yes I was thinking that too. Actually as no timer ability as been found yet except the VBL waiting routine, the only approximately correct way of doing this would be to have an assembly routine (or a C program where the assembly has been checked) (I dont know the MIPS assembler yet so please for...

Hi everybody, I dont think Sony care about homebrew... Bios 1.0 with a flaw? Good for us ! I bet somebody was fired or had bad time over there... :-) Find another hole in the 1.5 ? May happen. To come back to the subject, nem warned people about such possibility of running "untrusted" code...
