is there going to be a new snes emu?

[titch71]

There's a lot of room for optimizations in tyl (yes, I've looked at it). Is it that games without special chips generally run full speed and those with them do not, or is it generally not fullspeed?

Think there is a mix of both. The main games i've tried have variable results

Yoshi's Island - almost full speed in areas with high frameskip but slowsdown in others

Mario Kart - Seems to run pretty well at auto frameskip full speed IMO

Turrican - Requires frameskip and some other tweaking to get it to a decent speed.

IMO not that it counts much if there was room for optimization then it could make at least some of the least supported games run better.

I guess considering the 2 coders that were running with this project felt it was to much work for too little gain then there probably isn that much room for improvement without a lot of recoding.

I personally think TYL team made a landmark move in the PSP scene with their SNES9x emulator for PSP. Their work will always be praised and respected.

Though, even as nice as it is it's still very slow on some games/game sections + FX chip support was never achieved. Did I mention the final build is still a very buggy one?
Proof? Turn on SPC background music along with the spinning 3D graphics and try to change your menu background at the same time....actually, don't do this if you want everything in your memory stick to corrupt. This is the worst bug I've seen so far in any PSP homebrew application, and that's just one of them.

The source for this emu has been out and about for some time...I wonder if anyone's been playing with it.

On a final note, I believe Perfect SNES emulation is very possible on PSP. Just look at the last Game Boy Advance Emulator by Exophase and you, like me will believe....SONY sure didn't make that GBA emulator...now did they? There's CPS2/NEO GEO emulation for PSP (thank god for NJ)...now tell me why isn't SNES perfectly possible?

Wow, I didn't know that it had games not fullspeed with frameskip. On the Dreamcast we have snes emulation at basically the same level. From what I saw the biggest speedups could be made in games with extra chips, although there's plenty to go around.

Mode 7 stuff (I don't know how au fait you are with SNES architecture, so forgive me if this is basic stuff to you): hardward scaling and rotation, is the most awkward for TYL to emulate. Mario Kart and Super Tennis were pretty much unplayable last time I checked (Mario Kart isn't so much of a problem as GPSP emulates Mario Kart Advance perfectly. Super Tennis is more of a problem, though, as GPSP has major issues with Mario Tennis on GBA).

I haven't tried much that uses a Super FX chip (Starfox, Stunt Race FX etc), but Yoshi's Island is very slow.

I think my personal issues with Secret of Mana generally stem from Mode 7 causes. Moving clouds overlaid on the screen slow things down a lot, but then it does slow down when there are a lot of sprites on screen, so I dunno.

Generally, it tends to be a full speed emulator.

[edit] The above is without frameskip.

Just look at the last Game Boy Advance Emulator by Exophase and you, like me will believe....SONY sure didn't make that GBA emulator...now did they?

I don't know about the GBA hardware: does it have comparable hardware stumbling blocks like the infamous Modes, or do you just like being facetious?

I couldnt express my self better!!

and cmon, when ppl are saying that almost every game without special cips are SO WRONG!! i could say at least 20-30 games that needs to much framskip to be enjoyable on the psp

so plzz if some talanted coder read this thread, the snes wasnt coded wery well for the psp..

gAMES that need to much framskip to be fun to play:

Axelay
Biker Mice From Mars
Castlevania - Dracula X
Chrono Trigger
Donkey kong country I
Donkey kong country II
F-Zero
Mortal Kombat 3
Puzzle Bobble
Super Bomberman 3
Super James Pond 2
Super Mario Kart
Super Metroid
Super Turrican I
Super Turrican II
Unirally!!!!

many of these games arent using any special fx chip as i know..

[g00gy]

Yep ive had alot of problems with this emulator. And I personnaly hate frame skipping. I cant enjoy terrinigma, earthbound, star ocean or bahmut lagoon. Also there is a noticible amount of ripping in games becuase vsync destroys the FPS.

Those games (at least, not sure about the others) are ridiculously Mode 7-heavy.

Mario Kart plays fairly decently compared to the others, though. I'll grab my settings and post them here later.

SnesTYL is a bit overkill, it has way too many features and doesn't seem to be very optimized...

DreamSnes you say? I might have a look at it

EDIT: Source code doesn't seem to be available...

thats because they spent a lot of time on the emulator.. everything is already well optimized, probably close to as best you are going to get from a port.

of course, there would be a speed increase if you rewrote your own emulator from scratch.

vsync is really annoYing, if u put it on, chrono trigger runs slow, if u turn it off, chrono trigger runs good but the screen moves around weird.................although i love snes tyl, it is a GREAT and FUN emu, the gui is very cool, but the speed, stability, and compatibility can be improved...........PLEASE SOMEONE HEEEELLLLP
