@Natehaxx: There is strange "in game resolution switching" going on with the SNES core in games like Marvelous - Another Treasure Island, as can be seen here:

This might be related to different resolution modes on the SNES ("hires mode" in one instance, but not in the other). It makes a few games unplayable as of now.

(The stretched "view" seemingly is a default resolution mode on RA, Ive seen it with Tekken on the Mame core before.. )

Maybe this will get fixed, once aspect ratio scaling is in - but its something to bare in mind.

Yes, a few games use "hi res mode 7" which often switches from 256 x 224 to 512 x 244, 512 x 256 or even 512 x 448, depending on the game.

This is like a dumb question, but does anyone turn off there Switch after you done playing? Or is it just me been paranoid of it updating on it's own?

If you're paranoid, look up the DNS and update block guides for Switch in this section.

Yep, that should be it then (looking at the math). Just here to say, those games currently use something akin to 1:1 pixel mapping - which switches aspect ratio around "very strangely" - when the resolution switch happens.

Had a Funny talk with the Owners of RetroArch , they are saying in the future it could be a PS3 Emulator for RetroArch but here is now the Funny Part.

PS3 Needs an Core i7 8770K an Titan XP to run on the PC xDDD

Would just a 7700k and a 1080ti be close enough? :C

The Snes did some very weird things with its hardware.

maybe forcing the resolution would help ?

No idea, most emulators should be able to resize it just fine; Snes9x does just that, AFAIK.

notimp · Mar 19, 2018

Probably depends on how its implemented in Retroarch in general. (Trying to prevent conflicts with scaling modes, shaders, ...) Some feedback from actual Retroarch folks probably would be best.

Virtual Jaguar core added to OP.

hi, how is the situation in the emulation of gba/gbc and ds games?
I'm considering updating to 3.0.0 only for that, but don't want waste 40€ for pokken
How did games run? full speed or not?

notimp · Mar 19, 2018

If you are on 1.0.0 - DON'T. You'll probably get coldboot CFWs, which us other users will not get (yet/soon/theres always praying..

)
If you are higher, you may.

GBA and GBC pretty much run full speed, DS currently doesnt run at all (the capabilities are there, the libraries are not (need to be written)).

Biggest issues so far are - that

- It takes a pretty long time (more than a minute) from switching on the Switch to get it to start HBL. Sometimes it works first try, sometimes it works on the fifth try.
- Every time you start a current Retroarch build, there is busywork to do to set up the savepath and (depending on the core) bios path.
- Different aspect ratio support isnt in yet (in the cases you mentioned this means, no "full screen" modes, but only 3x(+) scaling (meaning small bars on all sides and only the core default aspect ratio)) (GB(C) may actually scale to fullscreen, most systems (including GBA) do not.)
- Digipad to Analog stick mapping isnt in yet.
- Savestates (save/load at any time) arent in yet.
[amongst other things, but those are currently the most noteworthy (in order), imho]

Thx Natehaxx for virtual-jaguar rayman plays and alien vs pretador too fps still low but rayman is still more playable these roms.

It will be really nice to see how much more power we'll be able to harness once we get a proper video driver built.

Gba version of rayman should run better.
