hey guys the link in the op, I don't believe is the latest one, if you click on the psx-scene link all of this stuff came linked from there.
In the faq it says 1.3 has lv2 the latest psgroove with peek and poke. I'm using the 1.3 led crazy one that was provided in this thread for now, I tried searching for another one that was a little bit more up to date, and the one I found was illness but his didnt work with pdfusb so I opted not to use it.
Dude Don't quote me on this but I'm pretty sure its safe to flash whatever hex on here as long as its not a boot hex. there is a separate hex for the bootloader, so you should be safe. Just choose cancel when you get an error with the program, that you get from the link for the tutorial in the op of this forum.
Program should say flash successful if it worked. If you use the hex I used in this thread, use pins 19 and 22 on the pic chip for the xbox 360 spi jtag. If you don't know what those pins are just go on google images and punch in the pic18f2455 and look at the diagrams.
Also I bought my chip from DIYGadget it was free shipping no tracking Number, but it came packaged up perfectly nothing was damaged, and came within 5-10 buisness days as promised, I got it the 7th buisness day.
