What is the Reason for Slow DreamSNES?

Why does this emulator work so slow? Are their plans to perfect it? Can they even perfect it?

The emulator works at less than full speed because it's still a work in progress. Try some games like Donkey Kong Country 1-3. They're all close to full-speed. Also, The Super Star Wars games work well. Those are just a few. I'm sure you can find more.

Hahahahaha! I remember being a newbie, but here's some advice: don't diss the emu or you'll get flamed and/or complained to BIG TIME. Yes, DreamSnes is still in developement and there ARE plans to make it run better, but until it works better, try the PERFECT NES or GAMEBOY emulators. These are some playable games. NONE of these games run flawlessly, but these run the best! Also, when using DreamSnes, turing transparencies and/or sound off in the menu will really increase the speed. Trust me, in time, you'll enjoy DreamSnes a lot more. I used to hate the speed, but I hardly notice it now.

Punch Out
Battletoads Double Dragon
Wario's Woods
Q Bert 3
Zombies Ate my Neighbors
Joe and Mac
Lemmings 1
Magical Drop 1
Mario Paint
Mario and Wario
Ms. Pacman
Side Pocket

^ These games should run really smooth with sound turned on and transparencies turned off. Please enjoy!

For people that can't stand skippy games, play THESE with sound turned ON and transparencies OFF for EXTREME playability...... {These run around 95-100% smoothness with full speed the whole time, which means NO slowdown}

I just hope they've got a new sound core written in SH4 asm since it seems to be the slowest part of Dreamsnes.

jessman · Post by **jessman** » Wed Jul 23, 2003 9:40 pm

wasn't it already written in SH4 asm?

BlackAura · Post by **BlackAura** » Thu Jul 24, 2003 12:44 am

Nah, just the main CPU emulator, which isn't really a major component of a SNES. The two most complex components on a standard SNES (no extra chips) are the sound system followed by the video system. Neither of those were written in SH-4 assembly.

The video core isnt asm, so there's something to rewrite. Sound I'm not sure on, CPU core is obviously asm. I'd guess if they were going for speed that's what they'd do. They obviously have the know-how to rewrite it. Its just a massive undertaking.

BlackAura · Post by **BlackAura** » Thu Jul 24, 2003 3:02 am

It's pretty much as difficult, if not more difficult, than writing it in the first place.

I hope NOT this release will exit on 31 october... by that day the holydays are over.

jessman · Post by **jessman** » Thu Jul 24, 2003 1:07 pm

Dang! This post is getting pretty long. Well, I personally think that the next release should be promising. Of course, we have no idea when the next release will be, right? But we DO know that the problem is the sound, so shouldn't it be easier to fix? I know that this isn't always true, but hey, the muted speed with transparencies off is fast enough for me. If it gets to THAT speed WITH sound and transparencies I could easily live with DreamSnes. But this brings me to another problem.....Is is just me, or do other people realize that some games run better with sound then without sound? I mean, on Battletoads Double Dragon and Ms. Pacman, the games get a lot more glitchly then with sound. Please let me know if you've noticed this in any games. Thanks, and SEEYA!

Maybe they took A Little time off. If you call almost a year a little time. Version 0.9.9? :nonoaliens:

Just Hope the next release will have a faster frame rate for some more

of my favorite games.

no you guys are wrong none of those games are full speed becuase they have frameskipping.. a game isnt full speed untill its the same speed as it would be on a real snes WITH SOUND.

I have tried over 100 snes games on the dreamcast and NONE of them run as good as they do on my real snes.

It has been over a YEAR since we have even heard from the dreamsnes team, i dont think they are working on it (i wish they were but lets be realistic here )

yes they did a great job so far, but theres a lot of work that still needs to be done and i really wish they would share their research with someone who will work on it because it doesnt look like they care about the project anymore, i think that instead of letting the project go to waste they should make it public domain or whatever its called and let the dreamcast emulation community take over the project. (only if the dreamsnes team isnt workin on it of course)

It just baffles my mind how a 200mhz machine has trouble emuating a machine thats 50x slower. The genesis emulator (i cant mention the name here) is FULL SPEED with sound (the sound is crap though).. and the genesis is faster then the snes.

I dont mean to be pessimistic (i think thats how its spelled) but we havent seen an update in over a year or even one word from the dreamsnes team that they are in fact working on the project. I think that snes is one of the greatest if not the greatest console ever created and i really wish i could play snes games on the dreamcast and it would be like on a real snes but thats not looking too likely.. im glad i have over 43 carts of snes games but being able to play all those games on the dreamcast (perfect speed , and sound) would be a dream come true. Theres lots of games that i have to use the pc to play becuase i cant find the carts or they are too expensive for me.

All in all, i HOPE that the dreamsnes team is still working on the emulator but i doubt it. Yes the dreamsnes is slow right now, (i dont accept framskippin and having to turn off sound as full speed). for now i will have to play snes games on my real snes and on my pc.. but i dream of a day i can play them full speed full sound on my dreamcast..

THIs is not to KNOCK the dreamsnes developers at all!! i am very pleased and im sure there are a lot of people here that are very pleased that there is even a working snes emulator on dreamcast. Its not near completion though and i wish it was .
