Hey guys, as I mentioned in another thread, I had been working on a proof of concept boot loader that lets you burn your own Saturn-like discs without the need the ring area or anything else that normally is needed for a pressed disc. It also doesn't require any hardware modifications. I've called it Pseudo Saturn. Basically it takes advantage of the fact that the CD Block looks for certain strings located in the first sector of a disc. If not present, it doesn't require any additional special checks to unlock full functionality. That's why discs like CD audio, VCD's, and Photo CD's work. Specifically the string I've changed is the first 16 bytes or the "SEGA SEGASATURN " string. Basically there's two parts to it: 1. Disc image patcher. The first 16 bytes are changed to the string "PSEUDO SATURN " and if necessary correct EDC/ECC data. 2. Saturn bootloader. Normally the bios won't boot a disc that doesn't contain "SEGA SEGASATURN " in the first 16 bytes, so basically a new bootloader is necessary. It was easiest to make a custom boot loader that runs on a cartridge with flash. And since most people own an Action Replay, it made it a good candidate to run the bootloader. Originally it required a patched disc image and some kind of custom boot loader. Now thanks to the work of jhl it only requires a custom boot loader. It takes advantage of a few flaws in the CD Block. Anyways, I've attached the most current build along with an installer disc image you run on your Saturn with an Action Replay inserted. There's more instructions and details in the package. Also please support Yabause, and guys like jhl, Druid II and whoever else I may have missed that contributes heavily to reverse-engineering and documentation of Saturn hardware. Source code is now available on github. It depends on the iapetus library which is also on github. I've decided to do one last release(v0.832) and then call it quits. I've mentioned in another post I've had some issues to deal with. Things haven't gotten any better since then so I'm officially done. The code is still and will remain on Github for anyone who wants to continue development. I'll even accept pull requests, but I won't actively contribute. Thanks to everyone who's contributed to this and made this community great. Too many names to mention, but special thanks to jhl, cafealpha2, zorlon. 09/19/2015: Added new cd loader by jhl.
