Homebrew lolSnes -- SNES emulator for DS

[the_randomizer]

Hoping to do sound for the next version

Also, the ROMs can be named anything. They just have to be in a folder named 'snes'.

Oh and you can't complete SMW. Autoscroll malfunctions in Donut Plains 2, and that bug probably affects every autoscrolling level in the game. (except the second part in Iggy's Castle apparently...)

How can I tell LolSnes to load a specific ROM, is there a way to select them? I'll be sure to test as much as I can I mean, how does the emulator know which ROM to load if there are several in a folder? Just wondering how/if ROM selection works when I use Desmume.

Why don't you run lolSnes and see by yourself?

lolSnes gives you a menu to select your ROM

You can bypass Donut Plains 2 by flying up to the key area in Donut Plains 1 before having the green boxes. It's a bit tricky, but it can be done. Then you can work your way to star world, and do enough of it to get to Bowser's castle using a blue yoshi. But Bowser is invisible, so the game is pretty much impossible to finish.

I'm guessing he's part of one of the background modes not emulated or something.

Thanks! Testing now

Slot 1 is Retail
Slot 2 is MPCF Flash Card Device (use path of loaded ROM)

Got it

Joe and Mac - Boots up, missing BG, stuck on world map
Kirby's Avalanche - Boots up and does go in-game, BG tiles corrupted, but it does work
Legend of the Mystical Ninja - !! 16 x 16 TILES NOT SUPPORTED.
Mega Man 7 - "SRAM Save" displays on bottom screen, no boot
Mega Man X - Boots up and goes in-game, missing BG and Mega Man shows up only when you shoot, HCOUNT IRQ ENABLE: B1
Super Mario World - Aside from the auto-scrolling levels, perfect (the text box doesn't open/close properly and a few transitional effects are missing, but it's all good)

All the Konami games I have tested result in the 16x16 tiles not supported error. I've more games to test if need be. Hopefully these results help somewhat

Thanks for project, tested rom Spider Man Animated (U) the game stop in the first screen with issues in the pixels.

Its just a report guys

Okay, looks like compatibility is not the best. Hey, that's a first release after all

Priority for the next release will be fixing that, I guess.


I started implementing sound, though. For now, nothing good comes out from the speakers... but that's revealing more bugs in what's already there. Double win!

Good luck on this Mega-Mario.

Since getting a PSP, I stopped caring about emulation on my DS as the DS emu scene seemed to have stagnated. So it is great to see people make an effort to improve the DS emulation scene.

Best of luck! If you need more testing done with the audio emulation, let me know

Tested Mario's Treasure Hunt (rom hack). It worked, except for a bunch of garbage in the middle of the screen.

 

[Arisotura]

Graah, I hate audio emulation, or anything relating to audio. When something is wrong, it's such a pain in the ass to figure out what >_<

Anyway, if there was a SNES audio specialist around here, it'd be cool.


One SPC700 emulation bug fixed. Now I get the right settings applied to the DSP voices. But bleh, my sound is all beepy and blargy. And I have no fucking idea why. I keep checking my code and it looks right.

 

[user64]

Well good luck with this project, it looks really promising!

Last I remember, Mbmax was trying to revive Snesmulds.
He done some coding and released one unnoficial version.
You should try contacting him, he has some experience and references to people who know how to do the DSP coding.

Best of luck to you, I'm excited to see what will come of this emulator

Nebuleon, could you bestow upon us your greatness?

Rom test
EarthBound Uncensored Patch - Crash
Mother 2 (J) - Crash
Super Mario Collection (JP Super Mario All-Stars) does display some stuff. Crashes before the Nintendo Logo
Super Mario RPG (U) - Displays the same thing from Super Mario Collection. Crashes.
Sparkster (U) - does work. Displays !! 16x16 tiles not supported on the touch screen. Starting a new game, black screen. Not very playable.
A Link To The Past (J) - Cannot see scrolling on name entry screen. Crashes when you start a new game.

It looks like all the existing emulators for the DS are dormant or discontinued, which is sad.

CATSFC was updated ~July 11th, actually -- though it's for SCDS2.

 

[Arisotura]

I don't count DSTwo. Mainly because I don't have one, but also because y'see, emulating the SNES on the DS is like a challenge, and it's cheating if you add extra CPUs

I posted the source code for this many pages back. Only no one did anything.

For SNES related stuff, you'd probably be able to get some help here:
http://board.byuu.org/index.php
If there's any place where you can find experts on the SNES, it's there.


Also, have you seen this? http://nocash.emubase.de/fullsnes.htm

 

[Arisotura]

I'll take a look there.

As for fullsnes, I'm aware. It's a nice doc, really.

And the SNemulDS source, well... I already have my project started, and it'd take me some time to fully understand someone else's code, so well...


About lolSnes, I tried running some of blargg's tests, and they don't even load. It appears they are HiROM. So apparently lolSnes fails at HiROMs, which would explain its low compatibility...
