Homebrew SnemulDS + Mario RPG = White Screen?

[8BitWalugi]

So, i tried to get mario rpg running on my DS as i just finished Mario & Luigi 1. When i try loading it, it just goes to a white screen.

Is Mario RPG just not supported on SnemulDS? Is is supported on SNESDS (I havent tried)? Or is it just not supported at all?

Can someone help!

SMRPG has a co-processor chip which all NDS SNES emulators do not support.

Maybe one of the three front-page topics about Super Mario RPG not working should be a sticky.

Wii is the cheapest system that can emulate this game adequately. Even PSP gets slowdown.

But SNES and real cart is less than a Wii...

It reportedly runs very close to fullspeed on the PSP with the right speedhacks (cough cough shameless self-promotion cough), though I've heard there are still some slowdowns in battles.

But yeah, not gonna happen on the DS.

oh... well, crap.
is the chip vital to the games citcuts? if its not, is it possible to make a patch that 'removes' the chip?

If you want a portable Mario RPG, just get a modified PSP. SNES9X_TYL (latest version) runs it fine.

 

[DanTheManMS]

The SA-1 coprocessor chip is imperative to the running of SMRPG. To exemplify, the chip itself is 3 times faster than the SNES's CPU. Removing it would cripple the game beyond repair.

Still, i dont want to buy a new handheld just so i can play a snes rpg... can anyone answer my question about the chips?

Edit: Just got answered. my reply, oh... but i still dont really understand why the chip is needed!

 

[Edgedancer]

The chip is needed as the game requires more processing power than the SNES is capable of making. How do you think that Starfox had 3d when no other game on the SNES touched it.

Well, technically there's Vortex, Stunt Race FX, and a few others, and IIRC there's a bit of polygonal stuff in Yoshi's Island, but since those are all Super FX/2 games, the point remains.

Kirby Super Star does "run" on PSP, but its performance is so horribly slow to the point of mind-numbing. A jerky slideshow...

Nobody was talking about KSS.

Good that there's already a topic on this... You guys say that the Super FX chip on the game is stronger than the SNES itself, but the DS already has rip ass graphics (like Super Mario 64 for example, which looks better than Super Mario RPG). So I still don't understand what's holding it back from working... they guy that made SNEmulDS even said he might give it a try.

Is there something I'm missing? Can someone explain this to me?

KSS has the same chip.

Emulating a coprocessor is a completely different thing to running native code. Imagine you have a fairly recent computer. It's technically more powerful than say, a GameCube, but you can't just run GameCube games on it because you have a decent computer; you need to emulate the hardware of the GameCube. This means that a program runs in the background pretending that it has all the stuff inside a GameCube that makes it a GameCube. While it's running all this stuff, it's also trying to run a game. The virtual GameCube on your computer is taking a whole lot of processing power, and chances are it's still not running at anywhere near full speed. And now imagine your virtual GameCube suddenly has an extra processor in it and it starts sucking more from your CPU. Whatever you plan on playing probably isn't much fun at 0.01fps.

I see, thanks for clarifying. I also looked around and finally noticed the difference between Emulating and Porting... thanks again.

oh... well, i started on emu. it froze when i got the 5th star (Jhonny's). can anyone give me a save file just past this part? on zsnes btw.

also, i heard of a luigi patch for the game. can anyone confirm?

ZSNES is a bit unstable for Mario RPG. Especially for the 1.5 releases. Use version 1.42 to get a fairly stable emulator. Or you could use SNES9x.

And I can't remember about the Luigi in Mario RPG hack. I saw some sprite sheets, but I don't know if there's a hack.

EDIT: I found it. It's called Super Luigi RPG. You can get the link on this page:

It's reported to be unfinished. The guy even plans to change Toadstool to Daisy.

Hmmm... all i need is to get past the spinning stars bit of smrpg. does snes9x support zsnes sav files? might give your suggestions a go.
