I need help to send Midi datas through cartridge port.
Hi everyone !
I'm coding an MPC based Midi sequencer for 3DS and it works as expected for now. Firstly, i wanted to send the midi data through the jack audio-out but it might be as complicated as changing the DSP sample rate (to match it with the Midi baudrate).
So, during my research, i've found a conversion cartridge "NDS to serial" called DSerial from natrium42, created around 2006-2008. The project's wiki is only accessible via the WayBackMachine so the downloads for the firmware, bootloader and others stuffs are no longer availables, but it describe the way to build it and make a midi controller !
So here are some questions :
- Does someone archived the necessary to recreate this project today ?
- Does someone knows a similar recent project (for NDS or 3DS) ?
- Is there an electronics-engineer/student willing to help me to recreate something like that ? (i swear it's fun !!)
- Does someone tried to run an original DSerial on 3DS ? (yeah, this one is very specific...)
- Is there a way to contact natrium42 ?
I'm a bit desperate to find out a solution to send Midi datas without wireless and i think i will readapt my code for NDS (with an mDS GBA cartridge for the data transfer) if i can't find out other solution...
