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...

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...

I would appreciate some feedback on the API for libslinga before I get too far along. libslinga: Saturn LIbrary for Navigating Gaming Achievements libslinga is a Sega Saturn library for working with save game files. The goals are: - work on real hardware - support as many backup devices as...

Here's my first stab at decompiling the backup library. There are a couple of places where Ghidra's decompiler couldn't resolve functions but it's disassembler could. I put in a ticket for it. This was mostly an excuse to learn Ghidra, dunno what more I'll do with it. I understand enough to...

Close to finishing Disasteroids. From the contest entry: - added the alien (every 4th round) - reduced speed of the player - reduced speed of the disasteroids - focused on making it easier to understand when you died vs when you completed a wave - added some more music - background stars Let me...

What does MiSTer mean for Sega Saturn reversing? I'm 100% a software guy, just wondering. Does it mean the interaction between the CD drive and the SH-1 are fully documented?

I created a new build that hopefully fixes the SSMTF pre-title screen. It sounds dumb but it's important to me to get that right at least. The fish is supposed to ominously come up and look around, then descend back down. On emulators it works, on real hardware the water doesn't render and the...

Hi all, I'm chugging along on my contest entry and I'm still stuck on how to do 2d collision detection with multiple objects. My game objects include players (1-12), enemies (0-10?), obstacles (0-5?), and ground (1-10?). All objects are using rectangular bounding boxes.I have AABB collision...

Removed.

I made some progress attempting to RLE01 compress\decompress the Action Replay's save data. I'm not familiar with how to flash the save data back to the cart however. My naive approach (I was hoping it would at least work in Yabause and fail on real hardware) was to do something like this...

I ordered a Sega Saturn floppy disk drive from eBay. The seller claims it worked before shipping. I'm not seeing any lights flash, any fans spin, anything. When I boot the FDD cd the drive is not detected. Things I have tried: 1) Using a multimeter on the original AC adapter. I'm having...

I'm interested in supporting reading\writing directly to the Action Replay save data in Save Game Copier. Any documentation on how the data is stored? And how to detect an Action Replay is present? Thanks in advance.

I need to still do some code cleanup but I'm pretty much done with adding features to my Save Game Copier (SGC). SGC can copy Sega Saturn save game files to and/or from internal memory, cartridge memory, external devices (e.g. Sega Saturn Floppy Disk Drive), Satiator ODE, and CD. More advanced...

I'm trying to insert a save game file into the Save Game Copier ISO without having to recompile. When I used Windows I believe Magic ISO let me insert files and save it as a valid Saturn ISO. When trying on Linux with mkisofs It looks like the file gets inserted, but the Saturn game header is...

I'm trying to find the RGB data for builtin wrestlers in Fire Pro Wrestling and I've hit a wall. By RGB data I mean literally the data stored with the wrestler template. See this image: You can see that they are 34 RGB values. For the user created wrestlers the structure looks like the...

@EmeraldNova has been testing my Save Game Copier re-write. He noticed that the Panzer Dragoon Zwei save didn't work when copied. One theory I had is that the comment on the save (which appears to change based on your in-game rank) was invalid. Also highly possible I still have bugs in my code...

I've made a little bit of progress understanding the FPS:6MS save format. Basically my strategy is to edit something in a CAW and diff the changes in the save. It appears to be working but it's slow. I've also figured out the checksum. Here are my results so far: // 20308 bytes in internal...

I just released the first beta of my latest project, Save Game Extractor (SGEX). SGEX transmits your saves via audio and let's you reassemble them on your PC. Save Game Extractor (SGEX) Transmit Sega Saturn save game files as audio to backup on a PC. Based on the amazing minimodem. Currently...

I created a thread on Reddit to crowd source 480p compatibility with various cables and upscaler combinations. If anyone has some cables I don't have access to (I tested composite, Euro SCART + OSSC, and HD Retrovision component cables) I would appreciate it if you could test it out for me. The...

I'm struggling to finish my latest project. I ported minimodem to the Saturn in an attempt to be able to retrieve save games over audio (to assist with fan translation projects). Here's a demo video video if you are interested. I have a few major issues: 1) I don't know how to stream PCM audio...
