It also doesn't require any hardware modifications. I've called it Pseudo Saturn.

Basically it takes advantage of the fact that...

I'm pleased to report that I've successfully dumped the SH-1 ROM from a CDB105 Saturn CD block. This involved removing the SH-1 from a CD block board, and attaching it to a Gameboy cartridge to provide ROM and NVRAM. A custom ROM loaded via the cartridge allowed dumping the ROM via the NVRAM and thence via USB; I'm very pleased by the fact that I didn't have to write a single assembler instruction in the whole thing (it's all linker scripts and C).

Here's the dumping rig,...

After installing, I got it to run original discs and music CDs, but when I tried burned discs it would keep spinning and stopping the disc for a while, like in short pulses, and take me to the menu. After freezing for a moment, it detects the audio tracks.

Here are the pics of the mod chip in question:...

I put everything in order like always, except this time my LED isn't turning on.

I tried to reprog 4 pics, tried with an other LED, tried without resistors, tried with another ground point still not working.

So I recently met someone that had a bunch of disks and cd's with source code and development tools from Sega. He said he got them at a IRS liquidation sale of a company in the Bay Area after the web bubble burst. Anyways I finally met up with him and took a look at the files.

There was a ton of stuff but a lot of it was Sega Saturn stuff so I'm posting here.

Why can't the hardware read the game when a 3D controller is plugged into the system? Anyone experienced this before?
Why does it happen considering that this is an issue concerning first party software and accessory...?

Can't seem to find much info on this strange issue.
By the way, console, controller and game are all U.S. that i'm using.

I have received my Rhea v3 from Denuan (the guy that made the GDemu) but am having trouble getting the correct files to run on it.

All the games I have for Saturn are BIN format - which I usually burn with IMGBURN.

However Rhea doesn't support BIN/cue it's preferred file format is cdi.

How do I convert a BIN file (or BIN/cue) to cdi? I've managed to get the BIN to an ISO file but that's no good
