Hello!
I desperately want to get the SAT2PSX converter to hook up my Sega Virtua Stick Pro to other consoles (chaining SAT2PSX with the Tototek converters). Paul Keio from keio.dk is the only known person who used to made such converters, but they are no longer in production so I've decided to build some by myself using description from his site.
They seems pretty easy to make, the only problem for me was the microcontroller stuff, so I've ordered two pre-progammed items from him. Unfortunately it didn't help because my order was not shipped and all my attempts to connect Paul are failing since the early april, but I was lucky to found an engineer at the local electronic forum who helped me with programming. As for Paul, he is like completely offline for some reason, and that's why I'm searching for the help/advice around the web.
So, the problem is that nothing works and I'm actually tired checking the stuff. Everything is built up exactly as it is described here. All wires are soldered to DIP socket pins in the provided order, both SAT1 and PSX5 wires are soldered to the pin 20 of the socket (and both SAT9 and PSX4 goes to pin 10), continuity is perfect, circuits are not shortened, 10µF capacitor across the 5V and GND is soldered with the negative side towards the GND. When converter is connected to PS2, LED is glowing with the plugged Saturn pad, and blinking with 3 sec interval without it.
ATtiny2313-20PU chip itself is powered by Playstation's +3.3V (which differs from the +5V at the wiring diagram, but seem normal, as there are no PSXs or PS2s in this Galaxy which outputs +5V to pin 5). Firmware file (which is Saturn_to_PSX.hex) is taken from the source archive and uploaded with the Phyton ChipProg-48 programmer. Fuse bits info from the text file

So my mind is really blowing off, I can't understand what I did wrong or why this stuff doesn't work, and I'm looking for any help on this case. Thanks ahead!

-U lfuse:w:0xe4:m -U hfuse:w:0x9f:m -U efuse:w:0xff:mactually seems to be the AVRDUDE code, which could be solved with the AVR Fuse Calculator.
