SCDS2 SFC EMU v1.06

SCDS2 SFC EMU v1.06
Unofficial Update

The SFC EMU v1.06 source code has been released and BassAceGold has made some unofficial changes to the emulator. No official change log for version 1.06 has been released, the change log below is for the unofficial version only.

• Added the ability to disable or enable audio
• Added cpu speed 5 which is only slightly faster than cpu speed 4, but its there for people who may think it'll help
• Attempted to reduce freezing of entering the emulator menu from in game (haven't tested to see if it works)

Special thanks to Chronos via IRC for the news!

QUOTEWith these changes, I have tested that Mario Kart is now playable with sound disabled on cpu speed 4 or 5. Haven't really done any other tests though so feel free to post results here.

how do i install this

 

[RupeeClock]

I just installed and then booted it, I'm greeted by a frozen menu screen.
I managed to get it to respond on a third boot, but that's not good.

Edit: The "Recently player Games" list has ActRaiser (U).zip in it, despite the fact I've NEVER played that.

Sorry about that, Might have to delete the NDSSFC.CFG file and reboot. If anything that would be the source of the freezing as I have had positive feedback from other users.

For those who already have the emulator installed, you just need to copy the .plg to your card, those who don't have it already installed will have to delete the NDSSFC.CFG after copying everything over.

Yeah, I deleted that and reinstalled, and it's working smooth now.
CPU Freq 5 has given a big performance boost to Super Mario Allstars, it's remarkably smooth now!

Actually I have a request, can you work on improving the scaling/display modes?
Being able to adjust scaling and screen position independantly would be a godsend.

What's current:
Display mode 0/1/2/3/4

What should be:
Scaling 0%/25%/50%/75%/100% (shave 64/48/32/16/0 vertical pixels)
Screen position Centred/Top Middle/Top/Bottom Middle/Bottom

If that can be done, it's be marvelous.

I think this is cool; an update not even from the official team!

 

[9th_Sage]

Wait, does this mean they gave out the source for it? Not asking for it, just curious. Also, thanks for the update.

 

[Pliskron]

I haven't noticed any improvement but this gives my hope that some day this isn't going to suck.

Fixing the display won't be easy. Currently the emulator handles scaling line by line which is convenient because the DS has the same horizontal resolution as the most common snes resolution. In order to get proper scaling, one would have to be able to scale horizontally and vertically which would have to be a pixel per pixel copy job and would cause a massive slow down. Currently I am testing such method (pixel per pixel) and even with cpu speed set to 5 and audio disabled, most games are unplayable. Sadly I don't think this emulator will get perfect scaling.

so now we have better game compatibility for the SNES? this is great its been open sourced

Is it really that much of an issue? SNEmulDS has its own way of letting you postion and scale the screens any way you want, quite effectively.
Or is the method employed different? I don't really understand why horizontal scaling is even necessary.

SNemulDS has access to the DS's video hardware to render and scale, on the DSTwo everything is done on the CPU. BTW I have updated the emulator to 1.07 and it does have a video mode with scaling so you can see how it runs. Its not pretty but it works.

can u had snesadvance.dat compatibility?it would help increase some speed on the games,just like the psp snes emulator
