Homebrew Saturn emulation using Cotton/Guardian Force testing and debug

[Purple_Shyguy]

I would love to do this but the explanation isn't very good for my understanding

What do you mean? Playing some games or building your own .NSP?

Simply playing the games is quite straight forward.

my ini doesn't save in the savedata, I have a workaround for it. But it's not ideal, as it breaks savestate.
I also use the same save file for all my games, as i've moved to using SimpleModManager to switch games.

But yes, you need to create the saves in the PC emulator, switch emu crashes when it tries to write to FDD.

Are you using the disc?

I'm able to copy to and from the FDD without problems

That could have solved the multi-disc games without saves in between.

hmm interesting, not sure then. Mine crashes

I'll try the non-english patched version and see if that is the culprit.

A little confused when he says "it's not known how well Dreamcast runs on the Switch" considering we've had full speed Flycast emulation for well over a year or more now.

Hey MVG I know you're here bro. Flycast! Retroarch and standalone!

The script is working - even if it throws errors at you like "failed to match key". Just ignore them. I've created 10 games so far using the script (all the same game) and installed them with Tinfoil. Tinfoil gave me an error every time I installed a game - and most of them didn't even work (blank icon loading thingy) but one game finally worked flawless.
No clue why - I've created every game the same way with Guardian as a base.

So if you get the script errors while creating your new NSp game, just try it out and check if it's working.

Can you tell me what game worked for you using Guardian as base?

Your problem is the path where you have installed the script, it is a long path but the real problem is that it contain spaces. I've fixed this, your language problem will not be after an update and the problem of return to menu of injection also, even with spaces in your script's path. If you use an other function of the script and have some problems it could be the spaces in the installation path, I'm not sure that this bug isn't somewhere else in the script. With the new debug function I want to review all of the code, I will pay attention to this problem also to fix it everywhere (I'll also fix the parentheses problems in path witch is a frequent possible bug, not present anymore in the Saturn injection).

aaah, thank you, I'll move to closer to the root of my drive and shorten folder names. Thank you for looking into it.

he didn't try it, i respect his work for Diablo port, but this video he is just quoting what he found here, Dramcast is running perfect on Switch either from FlyCast or the Core, if sega wanted, they could add it to nintendo Online Sub

its okay, we can hook you up with premade files MVG
we have a problem maybe you might want to solve for us!
since Zebra Engine Clever Programmers encrypted the GuardianForce.ini settings which was already decrypted by a user here Thank you cucholix !

we were wondering why they went the extra effort to hide the Emulator Config settings! now we want to know how are they hiding the Sega Saturn Bios, we tried several ways to load it, no go, i know this Emulator lives and feeds from Saturn Bios, they must have implemented it and removed the intro, i dont fully believe they remade SSF to work without it

can someone find out or decrypt the main and find out the truth

I managed to build an NSP with the script. New icon is there and it loads, however to errors come up, then some sort of frame with a menu that I can navigate. But the middle stays black. It seems the ISO isn't loading. I used Guardian Force.

Just to clarify, in the step of the script, where it asks for the cue/bin, I choose the folder containing those files, ricght? What name are the cue/bin expected to have?

Here's my full log. The game I'm trying to inject is Shining The Holy Ark (is this even compatible)? Any help is appreciated

Lower BlockClock to ~200. It should work.

Thanks, that got Jun Classic CC & Rope Club working!

BlockClock seems the #1 solution for black screen games.

Just discovered that it recognizes FDD saves from the PC emulator.
Recreate the Backup/FloppyDisk/Partition0/1 folders in romfs and add your bins.

Though you can read the saves, you can't write to FDD unfortunately.

Interested to know more about this setup.

I've never really used a Saturn so what is this doing? Storing save games outside of the Switch's save data?

pretty much, although I can't seem to figure out why I can't write to FDD, only read.

If your interested in trying, you will need to locate the Sega Saturn FDD operator disc, EnableFDD="1" in settings, create folder in romfs/Backup/FloppyDisk/Partition0 & Partition1

the issue is they both love to freeze randomly for no reason at all. its an issue thats been known for a long time but never fixed. I have to use Lakka to avoid the issue.

I've just set this up.

I put the folder structure Backup/FloppyDisk/Partition0/1 in my atmosphere/contents/etc folder

I set up a new item with only cue file in SimpleModManager for FDD operator disc.

FDD bin goes in atmosphere/contents/etc

And I can copy item from system/top/purple to cartridge/floppy/bottom/blue.

The bottom says that it contains 8080 slots.

One question, where is the file that represents the FDD contents located on my Switch filesystem?

the options are the same as in system Memory Manager

you will need to press left and right to switch memory

Sorry you'll have to be a little clearer? left/right on dpad? on what screen?

 

[xYuunax]

on the main screen pressing left or right will change to external storage if present, if nothing happens, then FDD is not enabled in your settings. Also keep in mind the ini is saved into the savedata, and changing ini will not do anything. you will need to export the save using JKSV, delete 'SaveData00088000.bin' and restore for the system to recreate the settings using ini again. Sorry if my explaination is not very clear.

 

[deathblade200]

so I havn't tried but I assume you could just delete the game files from the NSP and rebuild it without replacing them to save space and then just use layeredfs to replace them with the games you want to use
