Homebrew Saturn emulation using Cotton/Guardian Force testing and debug

[chobochobo]

So I've ended up installing everything - Atmosphere, sys-clk and cotton tribute. I erased my sd card and started again with the most current Atmosphere, and updated the firmware to the highest supported (which happens to be the current). I even re-initialized the Switch to really start from zero.

There was a frustrating few hours when I was trying and trying to get one other nsp that happened to be in directory to install. It would install but I would get a 'you need the software to play the game' error. Eventually I concluded that it happened to be that one game as Cotton tribute does install and play. However I've tried to put Baku Baku animal in there but after repeated tries I'm still getting the 'Error Code 2002-0001' which is what I got before and solved with making sure that the cue file/ bin files were correctly named. But nothing's working at the moment. Before I carry on, can anyone using the latest firmware (13.2.1) confirm that this Cotton 2 hack still works please? Cheers.

OK, update. It seems again to be related to the case - very strictly. I was baku.BIN in the cue file but the rom itself was baku.bin. That was even to incur the error. After altering the cue again to baku.bin, all was well. I even got sys-clk going again, and so far by experimentation I can get the music to play properly by increasing CPU to 1224 and leaving GPU and Memory as they were. Phew. Now to install retroarch and Mr Driller DC and I'm happy again.

How does Saturn Bomberman perform? And I assume there no one has sussed out multitap support yet? Is there a discord for research/findings on the emulator?

Plays perfectly, no multitap support.

Okay so i'm trying to make Bug! game but everytime i try to make injection i get an error occured during cue file analyse error and i can't get past that. I have the latest updated version of hack script in use and i have tested other file sources and usa and europe files also but everytime same thing happens. Is there a way to get past this?

Two questions. How can I move the memory card between nsps? How can I swap discs when necessary in multi disc games? For reference I created individual nsps for each disc

The input lag update is out! I'll download it after getting home but hope it does make the games a lot smoother!

Wouldn't the hack script need to be updated to support the update?
And from what I know this project has been abandon.

Can't source the upd to mess around with it

Considering this thread has more posts after I formally stopped looking, that's not a good indication of how active it is

I updated my cotton 1, and now it doesn't work. It loads the screens before the title screen successfully but error message before title screen

I'm still looking for the upd

If anyone has it for any of the three games or the collection, hit me up

I updated officially through eshop, is there a way i can help? Is there a way to find the update on my switch to help?

Ive also been looking for the update to run some tests on my end. Just found out about all this and got SOTN english patched running thru the collection.

btw, Is there a way to have multiple games set up or does it have to be set up every time u want a different game?

Update is available on jits... search for TitleID 0100094014BE4000 for the Cotton/Guardian Collection. I haven't been able to extract the nsp file though.

 

[lisreal2401]

Some stuff I gathered - haven't dug into executable, but a few things I noticed

Cue file is different - it seems a bit strange the offsets are entirely different for the same game... but

The ROM file for Boomerang is different - I'm not sure if this is purely out of optimization though the game is effectively 2mb smaller

I never decrypted the ini file, it's not impossible things were changed here

Pretty much all the primary stuff - cue sheet, game file, config and main are all changed. Going to see if I can make anything from poking the memory - the structure is functionally the same, it's difficult to get a single factor for what is going on

So it's 8 frames of input lag now instead 10?

That's still not great but ok.

after the update, black screen for me after choosing a game in the top menu
