Homebrew Saturn emulation using Cotton/Guardian Force testing and debug

[dragonz]

The reality is that wallpapers that combine scanlines don't work in Saturn games, and you can only see the borders, but you can't see the added scanlines. But this method does work in the NSO simulator, I will put two screenshots with the switch, you can see the effect very intuitively. One of them uses NSO's official original screen filter, and the other one is the display of the wallpaper I added the filter effect to. Hopefully, this approach may provide some ideas for improving the display of the NSO Emulator in the future.

The above is the specific display effect that I tested with the NSO Emulator here.Here is another video of the Saturn game after changing the wallpaper. No scanlines can be seen in it.

The scanlines you created look amazing! It’s definitely an improvement.

I apologize for being unfamiliar with the NSO emulator—I'm not sure what that is. From the screenshots, it seems to be a GBA emulator? Also, on an unrelated note, is the screenshot of the emulated game from Golden Sun? It looks fantastic!

I really hope someone more knowledgeable than I can figure out how to implement scanlines on the Saturn. Thanks for sharing that glimmer of hope!

By the way - I suspect that the wallpapers on the Saturn might have negative values—perhaps somewhere in the .ini file—causing the layer to appear behind the video feed. Sometimes programmers adjust the wallpaper values by adding -1, 0, or 1 to control whether the wallpaper is in front of or behind the video. It could be worth looking into!

Hello everybody! New here. I am reading a lot of this thread pages to understand.
I am using now NSP v1.2 by Markus95 to create the NSP and until now everything is okay except Nights that not perform well, do you guys have a place to find INI files for the games run smoothly? If yes i would be very happy.

The second thing is where to find a nice sega saturn wallpaper that I saw in a page, i could not find the file png or jpg

3th thing: there some ways to run these tools in a Macbook? If so, somebody would help me?

Thanks in advance and greeting from Brazil!

You don't need any INI files for Nights (at least I didn't). However, you will need to install Sys-Click and overclock Sega Saturn games to achieve full speed performance, especially for the 3D titles. For guidance, refer to 'How to Install SYS-CLK to Overclock the Nintendo Switch.'

Regarding your other queries, I am unable to assist. For the wallpaper issue, I simply use the internal rom tools to disable them, as I prefer the black borders. Unfortunately, I don't have experience with MacBooks and cannot provide assistance on that matter.

Dam this is crazy! I managed to get DIE HARD TRILOGIE to work, one of the best games ever!!!!

Can anyone help to change home screen coverart and disable left and right bars which still shows Cotton ?

This is how I did:

1. Install Cotton Boomerang Saturn Tribute[010077001526E000][US][v0] nsp
2. Create atmosphere\contents\010077001526E000 (place Config_Switch.ini and icon.jpg here !!)
3. Create atmosphere\contents\010077001526E002\romfs (put Saturn dumps here! E.g. game.cue and game.bin)
4. Rename game.cue to CottonBoomerang.cue
5. Start!

You can use CaVE to generate these games with your own custom side images and what not. It’s in public release now. One single game, not multiple in one.

Thanks! What about wide-screen? Mentioned it is working for N64 only. Maybe working for Saturn as well?

 

[SusumuNoDS]

developer is still active, you can request the future for your needs. I think wide-screen is a hack upgrade

 

[soldiaz]

Really, still active? I searched for contact, could not find

Id like to supply translation

city-connection.co.jp I don't know how popular this game is. But when played it doesn't crash or glitch
