idea: flashing PS1 PIC's Updated: new idea

All the information you should need to homebrew a new mod chip is available here. There's even VHDL code if you want to build one with an FPGA.

interesting thinks for the link lol

It looks like there's also code for a CD emulator there. That would be an amazing product if commercialized. Imagine a PowerPak/Everdrive type device for the Saturn.

lol it would be a lot like the X360key

i also seen this:

The security ring above is how it appears when it comes off the disc or modchip.
Bytes 12 thru 2352 of a sector in mode 1,2 etc data is scrambled(xor) with LFSR, so to record your own security like the above you need to
XOR it before you write it to your ISO or bin/cue file or whatever.
A dump of real security ring data.(0x59 is background data, 0xA8 is logo data, check ecma-130.pdf for efm bit patterns)

so i was wondering if it was possible to make direct booting saturn copys with that info....

Well, I'd be interested in PS1 PICs. I've got a bunch of old PS1s sitting around. I got a guy in my country to program a PIC for my Saturn (well, I just got him to install the whole region-free mod because the solder points, I decided, were too small for me).
