Re: JP 5500 - MM3 not booting
I purchased a new PIC12c508a, flashed Mayumi v4 JP hex, and have the exact same result as before (won't boot past white Sony screen with burned CD). I have a strong feeling this laser is no-good. The replacement is a KSM-440ADM, are these ones on eBay ok or where is a good place to buy a replacement...

Re: PSNee further development
Hello, if I have an eprom programmer that can program ATtiny45/85, is there a hex file somewhere for psnee? I'm an Arduino noob and would rather not have to buy the Arduino Uno just to program the ATtiny45 if my eprom programmer can do the same thing.. ty in advance. Hey, I am not sure but I think ...

Re: JP 5500 - MM3 not booting
Update, it plays audio CD's without issue, plays burned audio CD's also. There must be an issue with the way I'm burning these JP roms. I just burned JP region .cue to CDR, or maybe it doesn't like the blank CD's I'm using?

I verified it can read an audio CD but no burned roms (TDK, are they junk)? I found t...
