I have rescued from the basement the MP3MSX cart I have in a box well protected. It is the original Yobi version without case I used some times and even recorded a video.

However, I have not been able to make it work again and I get a "Bad header" error when I try PLAYINFO.BAS, no matter the MP3 file used. Some info about my setup:

MSX: Panasonic FS-A1GT
Slot 1: MegaflashROM SCC+ SD or Flashjacks
Slot 2: MP3MSX
OS: NEXTOR 2.1.0 beta 2 or SymbOS 3.0 (using SymAmp)

Other config I tried:
MSX: Panasonic FS-A1GT
Slot 1: MP3MSX
Slot 2: None
OS: MSX-BASIC (loaded the PLAYINFO and MP3 file from floppy)

Is my MP3MSX dead? How can I test if the cart is alive?

Hi! Probably you need to re-flash the flash-rom. The flash-rom on the original MP3 from sunrise is a bit weak. I had the same issues. It started with once a year, than once a month, and now almost every time when i use it i have to flash it first Wink

You can replace the flashrom, or you can buy SE-ONE, which is fully compatible. I have the flash basic program. If you like i can send it by email.

EDIT:

I uploaded it here: My HomeDrive

You have to run it in z80 mode! (3.5 Mhz) run the basic program, it has the updated HEX program for the sunrise! Be patient. It is done when you are back to basic prompt.. sometimes it takes a time and this is random for some parts.. so don't stop it when you don't see the basic prompt ;)

Hope that helps!

Thanks edoz! That did the trick and my MP3MSX is living again!

I am wondering how it is possible that the flash loses his contents and if the chip can be replaced with other.

Good! I know the chip can be replaced by a hardware guy or woman. But don’t ask me about detailsWink

@karloch This microcode seems to be the version I fixed and compiled. You can listen to MP3 with GR8NET using it, GR8NET will detect external cart and play MP3 audio through it from network or SD-card.
