Max CPU overclocking fixed the input lag in Panzer Dragoon for me, the difference is day and night

BTW I don’t use nsp installation, I do title override if someone is interested in this method to avoid risk of being banned.

Would this allow for the use of multiple games then?
If so, I would love to know.
Also would love to know how to do the name & icon changes, assuming those are legit changes and not the LayeredFS route with drag & dropping an image into the content folder.

Why would you make stretched widescreen, the worst aspect ratio, the default shared config?

I was using this emulator day one, with my own properly made custom nsp. I'm wondering why you're sharing that trash with others.

you can stop your Trash talk and go back to your cave, if you are going to talk nonsense in public, avoiding you from now on
if you wanted to show off, then share your files, if you dont share it then dont write anything

These settings persist until your save is edited or deleted, so it's adviseable to have the cleanest/best settings in place by default for the people you're sharing with. Stretched widescreen is an abomination.

Looks like nobody shared this yet for some reason but there's a tool for decrypting everything from your own dumped files: https://github.com/shadowninja108/STD/releases

Pretty awesome compatibility and speed so far, ive needed to OC for some games but pretty much full speed for most games ive tried. Fighters Megamix, X-men VS Street fighter, VF remix.

Question for the more advance users, some games volume both music and sfx are really low and some are normal... is there a way to increase sound? was looking at the provided .ini and saw the line for volume so I increased it but so far notice no increase in volume? Anyone has had any luck with increasing the volume?

You'll need to delete or edit your save for the setting to take effect.

Thanks for this...
Sound on Cotton2 & Boomerang is at 0.70 while Guardian Force is at 0.93? huh..

Also if you do indeed have a method of creating custom NSPs so we aren't limited to 4 (well, 6) games, definitely fill us in.

Dumping was only to experiment with the files and get an idea of the workings of it. To actually play Saturn games you dont need to dump anything.

Simply;

Install one of the games. Either the Triple Collection or each game as a standalone depending on where you "get" the game
Create a Title Id folder of your chosen game and place in your "Contents" folder for atmosphere or "Titles" folder for SXOS.
0100094014BE4006 for Collection
010077001526E002 for Boomerang standalone
0100A18015268002 for Cotton 2 standalone
Place a "romfs" folder inside the title ID folder
Place your Saturn roms in romfs folder in .bin format
Rename the .cue file for your saturn roms to either Cotton2.cue for the collection/Cotton 2 standalone or CottonBoomerang.cue for Boomerang Standalone
Reboot your switch for changes to take effect
Launch game.

Tried this with both standalone Cotton 2 and the Collection. Tested Sakura Taisen and Policenauts, both English Patched. None worked, stuck on black screen after the initial logos/Playing Guide. I must be doing something wrong or I'm just extremely unlucky and the only two games I've tested won't work. Can anyone confirm?

EDIT: SOTN english patched worked, so I guess Sakura Taisen and Policenauts are incompatible as of now. Maybe it's because the cue file mentions .wav files (in both of these games)? Can anyone experiment?

So I've been looking into this for a bit since I saw your post an hour or so ago.
The emulator doesn't seem to support ISO+WAV+CUE (which falls in line with older versions of SSF).
I converted my already patched copies of both games to BIN+CUE using AnyBurn.
After doing such, both games work perfectly.

Open AnyBurn -> Select "Convert image file format" -> Choose the .CUE file as the source image -> Make sure "Select image file type" is set to .BIN/.CUE and click "Convert Now"

Simple as that!

When i change any .ini settings and they take effect in game when i now try to save state the game locks up and needs to be forced closed.

Is there a really simple way to create custom nsp file so i could have proper images for my saturn games?

Setting bilinear to off (0) in ini doesn't seem to have any effect. Any confirmation and workaround here ? Thanks.
Tested with single eshop Cotton2 NSP and layered romfs with Albery Odyssey swaped.
Thans.

I've managed to create an injected game with a custom Title ID, Title Name, Publisher, Version and icon, I can create as many games I want now. For now my script is only usable with Guardian Force, need to be adapted for the 3 other games and need to make the error controls. After that I will make the ini edit more friendly.

The ini is saved into a savedata upon first launch. So any additional changes later won't take affect unless you delete the save to startover. You can turn off bilinear in-game, use the option menu. Other workaround is to edit the save.

I noticed the save file had some additional settings.

Can change the emulator defaults like wallpaper, language by adding to ini.
