Re: JP 5500 - MM3 not booting

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?

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?

Re: JP 5500 - MM3 not booting

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