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.

That makes sense, I followed your guide on github

Floppy was disabled in my ini for FDD.bin, now it's enabled I see panels for side 0 and side 1 of the floppy.

I put a test save game in there that I found online from Sonic R and it shows up. But as you say I cannot copy anything into the floppy without getting a Switch UI error.

Are you using the disc?

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

Can you please expand on this?

Floppy memory should show up in green.

Purple is system memory, blue is cartridge memory.

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

Yes, you can do something like that.

Did anyone try Shining The Holy Ark yet? Managed to get Panzer Dragoon Saga to run via script, but Holy Ark does not work for me.

It's important for people to know, these are the only multi-disc games that require an immediate disc swap.
Every other multi-disc game NOT listed requires an existing save file instead.

3x3 Eyes - Kyuusei Koushu S (Japan)
DeathMask (Japan)
Desire (Japan)
Doukyuusei 2 (Japan)
Eberouge (Japan)
Gekka Mugentan Torico (Japan)
Haunted Casino (Japan)
Lunacy (North America)
Lunar 2 Eternal Blue (Japan)

- Ultimate-Switch-Hack-Script
- Standard config.ini from Guardian Force

Didnt take any changes.
Holy Ark is typically one of the easiest Saturn games to emulate.

Which region is your ISO from? Mine is the US one.

US as well and as with any other game I test, the bin files were combined (this may or may not matter)

What do you mean by "bin files were combined"?

The .bin files CD games have that go along with a .cue file.

Well, since I'm newbie it appears I cannot send you image or link to it via PM.
So, I'll attach it here. It's nothing personal, just japanese style saturn logo for splash screen =)
I'm not sure which editor was used for this particular pic, cos I've been trying a lot (to reduce size as well), but all of them are crashing the game the same way. Thanks!

i attached the version you sent and the one i was working on
have not tested them yet but they should work
when i have the time to finish a Full Asset Swap, ill share the rest

shadow256 · Oct 18, 2021

I've made some tests and sometime a game image could cause problem even if it's a .cue and .bin format witch work on PC. For my test I try with Baku Baku Animal and my first launch was a big fail, two errors and black screen after the first screen to pass. So I've rewrite the file with Cdmage and the game has been finaly launched, audio is realy awful (I've tried to modify some settings in the ini but no change) but the game work. After this I look into the files differences and in the .cue file the path to my binary wasn't good because in the Switch it is case sensitive so be careful with this.

Thanks you for your time, but it doesn't work as well. Maybe it is size related? I have an idea...hmm

yes i noticed if the font
is AKUMAJOU DRACULA X (TRACK 1).BIN
AKUMAJOU DRACULA X (TRACK 1).CUE
or inside .cue text

you must change all to small letters, nothing will work in CAPS on switch
