Topic: Hardware

The Flashjacks cartridge by MRC user Aquijacks received a firmware update:

V2.0 (26/02/2022).

  • Added WAV playback function in PCM and ADPCM formats. It allows playing songs, pausing, stopping, etc from the FWAV program.
  • Song trigger system is added by changes in memory position. This allows you to swap game songs for WAVs at will.
  • Fixed PSG bug remaining activated in certain situations indefinitely (e.g Aleste 2).
  • Fixed reset bug. The reset pulse is lengthened so that the audio chips reset correctly, avoiding artifacts.
  • Fixed another reset bug. While on reset the Flashjacks RAM is disconnected from the MSX refreshes and doing the minimum vital refresh to avoid data loss.

Indirectly controlled playlist to substitute the in-game music with WAVs is very clever idea. I hope there would be more packs for other games available, like the one for Penguin Adventure. Didn't try it myself yet (covid makes me really tired all the time and weak), other day i would try it right now but i'll wait a few days. But from my understanding this feature are very interesting if it gets some more custom in-game playlists from people Smile Also, the idea itself - brilliant, Antonio!

As this is such a wonderful device, but not for sale.. perhaps the community can step up and have this publicly available. There's plenty of hardware gurus and sellers around. Which makes me wonder why there's so little collaboration (or at least that's what it looks like to me).

So, how many AJ devices are around? a few?

I wish you get better soon, Pencioner! Covid is no joke.

Incidentally, I'm curious about the Flashjacks. How many cartridges were produced? How many people have one of these cartridges?

Few units are in circulation. It is a personal project of great proportions. More than 3000h of programming and synthesis and a decade of designs.
At the moment I allow myself the license to keep this project private.
It is possible that one day I will publish the source of this project but for now I reserve that license.

WAV playback function is impressive.

Personally tried on MSXVR (I don't own the unreachable Flashjacks)

Will be fantastic to have same work for games as Ys 1-2-3, SD Snatcher, Valis 2, ecc....

Are the game packs available? Is it possible to those that dont own a flashjack or a MSXVR to try it using a MSX emulator?
