Was 2400 bps there before, or is it a new speed?

I think it's new
12Me21#3
Why is line 24 commented out? 
'IF ((EXTFEATURE AND 1)!=0) THEN USEPCM%=1
I uncommented it and the PCM seems to work fine (at least for 3DS->PC transfer) even at 2400 bps

Because I have not tested enough the PCM feature on old 3DS. If it works, you can use it. but I think you don't need it. PCMstream has two advantage. one is "continuous wave" and the other is "low quantized error". In this version, All packets have "two sec" length which is capable even in WAVSETA. and the quantized error is small enough at 2400bps according to my calculation and measurement. I think we need PCMSTREAM abobe 9600bps.

Oh, mine is outdated
Gale_Storm#6
Looks like it's time to update it.

This works much better than the previous version on my computer!

Can you add a simple browse for files option in the LZSS as an alternative to the drag and drop? I'm a Linux user and Wine does not support drag and drop.

This looks great, but alas at the moment I don't have a PC with windows.

More Windows-only software. DansGame

Hey, rei, you've made a very good job with this one! I have a request - can you please either make the PC software open source or replace winmm.dll with https://github.com/naudio/NAudio? Your software runs perfectly fine under mono, and winmm is the only thing that prevents it from being functional on Linux/OSX.

According to http://smilebasicsource.com/forum?fpid=14093#post_14093, adding a 1K resistor between ground and the 3DS' MIC line helps... but that info is more useful here than there, so I'm repeating it here.

That is strange.

I was using a 3.5mm AUX cable, that only carried sound from the 3DS to the computer. The settings were Simplex with 600 bps

Simplex only needs 1 way communication.

How would I know i I had the framework installed? I finally got a pc running windows and I would like to test this out

Just download the program and see if it works. I'm pretty sure .NET comes with windows.
