What happens when you try the burned CD (not ISO) in an emulator? I'm assuming it will work? That should rule out a bad burn right?

Unfortunately I don't know what advice to give you. Your save looks correct and the ISO you made works on an emulator and boots on hardware.

Can you try a linux VM?

@JBeretta well deserved win!

Yeah that's the latest version. I never finished the game... Here are some other multitap games I've worked on: Build software better, together

I edited the competition thread a bit (moved comments out of that thread to this, combined 7shades posts into one, etc). Let me know if someone wants something changed.

Contest organizers: I changed my zip file at 19:06 PM, after the contest deadline due to an issue in my .cue. Please deduct points as necessary. Ran out of time, but here's Sweeper Squad 0.9. 12-player Mine Sweeper clone. Runs at 480i and includes mouse support. Will finish this blurb tomorrow.

@not-AI-generated , Cool stuff. Obviously you will get more people to try out your game if you implement controller support. But I'm sure you know that and ran out of time. I swear there is a memory mapped register you can use for random (pseudo random?) values on the Saturn. If not you can...

@MAZter , Another thing you can try is running satconv (or another tool) to dump the peripheral codes from each game ISO. According to Gamefaqs the keyboard code is "K".

Thanks, v6.347 booted just fine with the swap trick.

I'm trying to use @cafe-alpha 's Save Data Manager V6.483 by burning pskair_sdm.iso from pskai_release_20211113. On Yabause it looks like it works. On my real Saturn (via swap-trick) I can get it to boot to the "Saturn Save Data Manager -- V6.483" title bar and then nothing. It looks like...

Here's a screenshot of how four controller look like on the Honest Multitap. This is using Jo Engine's multitap demo.

Johannes recommends IrfanView: 8bit Demo Questions · Issue #57 · johannes-fetz/joengine I recall having issues with GIMP converting to TGA but IrfanView worked. Assuming you are using 24-bit images: TGA, no compression, export bottom left. I believe that should work.

Can you extract your SSF save to the .BUP file format? With the .BUP save you can inject into into a ISO and load it on any emulator (using Save Data Manager, Save Game Copier etc).

I ended up going with a large (1024 bitmap). I checked in my code to GitHub - slinga-homebrew/libslinga: Sega Saturn save game library. The basic idea is each bit in the bitmap represents a block on the partition. g_SAT_bitmap[] is a large bitmap used to store free\busy blocks each bitmap...

Still working on libslinga (GitHub - slinga-homebrew/libslinga: Sega Saturn save game library). I'm trying to think of an algorithm to read a Sega Saturn save file without the need for malloc(), large stack space, or a large global buffer. For Save Game Copier I used jo_malloc() to allocate a...

@BrokenLizard: I appreciate your document. I spent a little bit of time comparing it to my own reverse engineering efforts: Decompilation of Backup Library. In terms of the CRC length, I believe at some point your document listed it as 4 bytes. If I am mistaken, I apologize. As you mentioned...

I uploaded a very early WIP build of the code. Partial support for reading from the Action Replay, nothing else. GitHub - slinga-homebrew/libslinga: Sega Saturn save game library. I would appreciate any feedback.

libslinga - Sega Saturn library for working with save game files

I'm basically splitting the backends of Save Game Copier out into a standalone lib: Save-Game-Copier/backends at master · slinga-homebrew/Save-Game-Copier. I will use only MIT code. I don't think anyone on Saturn is using the C time libraries as time() is not going to give you the current time.
