SnesPSP-TYL = Change ?

[tryqus]

So with the release of SnesPSP-TYL by Yoyo (my personal hero atm) we actually see the psp hardware being used to emulate another system (partially). Can this be employed in other emulators, such as say...the gba emu? I dont mean to rush the man, im more then happy to play snes while i wait, Im just curious if we will see this mixed rendering in his future emus.

On a side note, has anyone been able to get starfox running on TYL? It acts as though it wants to run at a playable speed *audible gasp* but theres a lot of glitches and eventually the ship disappears all together. At least it doesnt crash my psp :eh: . Im going to try another rom.

The reason Starfox doesn't run is because a lot of the effects in the game (mode 7 etc.) have not been coded to run off the graphics hardware yet. This will be fixed in future emulators (he even mentions this in the readme I believe). We are only at the very start of fully using all of the PSP's hardware YoYo has said that he plans to use the media engine for sound emualtion taking even more strain off the cpu. Once all this code s fully optimised (and it is far, far from being so what with this being version 0.1 or something) the potential for this type of emulation that uses atleast three different processors is emmense. Believe me when I say that we will see some amazing things from PSP homebrew devs in the future, I mean the media engine runs at 333mhz aswell if this, the main cpu and the gpu are fully taken advantage of then.....wow! And yes, GBA emulation will be well within our grasp, it will just take time.

[tryqus]

Ah right I remembering reading about that but wasnt sure if it pertained to Star Fox. Ah well im sure he will get it running soon enough.

[socalledsin]

there was and update on his page today that the next version will be out soon.

[ohgod]

So with the PSP's other processors being used, what other systems will be emulatable? N64,PS1?

[Axeus]

PS1 is already being worked on, and i think an N64 one is too, but i dont know how they plan to map out all those buttons.

[anidiot1]

dont worry bout buttons. Right now i think getting them working decently is what we should worry bout. And anaway someone had mapped out the n64 buttons. I cant remember who though.

[tryqus]

I saw a picture of the remapped n64 buttons somewhere around here. I'll look for it later. Rest assured though they have figured it out. Anyway why not simply allow us to map the buttons as we see fit?

-Tryqus

[Axeus]

Because the N64 Has around 20 buttons.

[kennyk]

Try
N64: 10 buttons
PSP: 8 buttons

And of course the n64 has an analog stick and a dpad, but I don't know of a many games that require use of both.

[Axeus]

WRONG!

N64 Has:
A Button
B Button
4 Yellow(C?) Buttons
L Button
R Button
Z Button
4 Directions=
13 Buttons+A-Stick(6 Directions)=19.

And when i used to play jet force gemini i used every one of those buttons.

And HOW would we get to the emu options screen?

[Labounti]

Hes right the D pad is used like buttons in games like Turok1,2,3. But games that use the Z button normally dont use the "L" button, Z acts as "L"

Star fox does not use mode 7. Pilotwings is mode 7, star Fox is Super FX.

Forget the N64, its nearly impossible to emulate a cpu that is superior to the one emulating it. R4000 trying to emulate an R43001. Instead more realistic ones would be GBA and Neo Geo MVS.

[joshwaan]

Hey guys

I have not had a chance to play this snes emu, but can you stretch the game to fill the screen?

Also if possible could someone post some pics of it in action

Thx

The N64 prcessor is not superior to the PSP's, yes it is 64 bit (whereas the PSP is 32 bit) but it only runs at about 93mhz whereas the PSP's runs at 333mhz.

[CamCam]

yea but you dont understand that the processor has to be 3-4 times faster to emulate it properly, I dont understand why people think it is possible to emulate something like the N64, the ps1 might be possible but it would have to optimized and maybe fullspeed on certain games like symphony of the night for example a 2d game, anyway dont get your hopes up

[OblivionX]

emulation requires closer to 10 times the speed for playable framerates I would say. N64 will never run fullspeed on a psp, even if the whole screen was glitching due to inacurate calculations in an effort to raise the fps.

[CamCam]

yea i knew i had the number wrong, been awhile since ive coded

[brain_stew]

Eh...... when did I say N64 would run at full speed? Please show me the quote because I have never said this. We will see some sort of N64 emulation but it won't be good. Remember tho, the PSP has a lot more than just its main CPU, it has a very capable GPU and a second 333mhz processor although at the moment it is unclear whether or not that will be much use for anything other than sound.

[CamCam]

Just saying it in general because there is awful lot of threads talking about how they want a fullspeed N64 emu, and all the gpu is gonna do is take stress off the processor and that still wont help it a bit.

The N64 doesn't have a select button, so maybe the PSP's select button??...
What about having to hold a button (like L or R) while pressing the D-Pad or Face buttons for those other buttons??

isn't N64 emulation easier on PC hardware?

the r4000 is just as 64bit as the r4300 is, they both have 32 and 64bit modes of operation.

[acdbrn]

the major problem with using a n64 emulator is the buttons has anyone hacked the psp dedicated butons like the home and sound buttons those could be comendered for other purposes.

[tryqus]

The PSP will run under two 32-bit MIPS R4000 microprocessors

The N64's RISC CPU is a 64 bit R4300i running at over 93 MHz

In 1991 MIPS released the first 64-bit microprocessor, the R4000.

In recent years most of technology used in the various MIPS generations has been offered as building-blocks for embedded processor designs. Both 32-bit and 64-bit basic cores are offered, known as the 4K and 5K respectively, and the design itself can be licensed as MIPS32 and MIPS64. These cores can be mixed with add-in units such as FPUs, SIMD systems, various input/output devices, etc.

MIPS cores have been very successful, they form the basis of many newer Cisco routers, cable modems and ADSL modems, smartcards, laser printer engines, set-top boxes, handheld computers, and the Sony PlayStation 2.

Lot of interesting data, thanks to wikipedia.

I wont lie, I would kill for N64 emu. But as hard as it is to emu N64 on the pc, I cant imagine it being any easier on the psp (undoubtably harder). The gba is a much more realistic goal imho. 32-Bit ARM running at 16.7 mhz. The psp's cpu is what, 20 times faster? Oh course it isnt apples to apples considering they use two diffrent cores.

I was also wondering, what are the chances of any of the 32bit systems being emulated? The Sega Saturn, the 3DO, the Sega 32x, even the Atari Jaguar (who would want to emulate that :P)? We've done great things with the 16bit emus, and now we're debating about the 64bit system? It just seems that we've skipped an entire generation of gaming systems.
