Darksoft Neo Multi Help thread

Hi,

I'm experiencing some audio issues with my Analogue Slim CMVS (MV1C board). In some games, the audio plays way too fast—this also happens with the music on the Neo Geo loading screen.

You can see an example here:

I've had the Neo Geo inspected by two different technicians. Neither found any faults on the board and both suggested I check the multi-cart instead.

I'm using the first batch of the MultiMVS with the latest firmware.

Are these known issues? I haven’t been able to find any information about this online.

Thanks!

The rhythm of the music is defined by the timer on the sound chip which is part of the neo geo board. That is controlled by the Z80 which is also part of the neo geo board. The multi cart only provides the program for the z80 to run. I suggest you try the cartridge on at least one different MVS board of any type and confirm if it has the same issue. There is a slim chance that the neo geo board has a fault on the sound circuit.

Even the eyecatcher music is playing overspeed.

Does this happen on all games?

Thanks for your reply!

I asked them to check the Z80 but they couldn't find anything. The 240p test suite Z80 doesn't give an error.

It doesn't happen on all games, i would say 10%-20% of all the ones i tested.

Unfortunately i don't have another MVS board to test the cart, but also hearing from Darksoft that he never heard of these issues believes it's still the Neo board.
