update: I wrote a very crude WAV conversion utility in JavaScript, here's the repo on GitHub:
https://github.com/nippur72/commodore-tap-wav
I tried to load both on the VICE emulator and FPGA and they do work, apparently.

Re: Vic 20 Basicode
I had a look at Mister source code, and it seems the WAV loading has been removed from some reason... that's a shame! I also don't see the AUDIO_IN connected to the C1530 as in the MiST version... I guess they are not aligned and the Mister is lagging. I hope that will be solved quickly. If I have t...

Re: Vic 20 Basicode
I've read the Wikipedia article and looked and your PR, that is very interesting! The BASICODE format looks similar to the Kansas City Standard, for which I wrote a encoder/decoder program (see https://github.com/nippur72/z80ne-wav it's called "Z80NE" because it was used on the Z80NE compu...

Re: Vic 20 Basicode
I don't know much of BASICODE, how do you create such WAV files? And more importantly, is the same WAV supposed to load on different systems? That would be very interesting. My guess is that it does use each system's ROM routines for saving and loading--if so, the actual audio recording would be not...

Re: Vic 20 Basicode
are you trying to load the BASICODE interpreter from the .wav file? or a basicode program that you have previously encoded in wav? Generally speaking, WAV support for the VIC20 is awful, I also experienced lot of troubles, so when I have to deal with an audio recording I plug the FPGA or the real VI...

Re: Vic 20 Basicode
The saving program also loaded flawlessly on the first attempt:
Here is a floppy image containing the two, LOAD and SAVE:

Re: Vic 20 Basicode
this is a very clean recording. It did load on the FPGA on the very first attempt.
Here is the .D64 containing it ("vicloadbasicode", discard the rest):

Re: Vic 20 Basicode
if there's anything we can do, we have to do it before the WAV to TAP conversion. TAP is a 1-bit encoding where all the useful amplitude information is lost.

Re: Vic 20 Basicode
I tried to load it on the FPGA (where I have the sound monitor) via a car-audio cassette adapter but I did not succeed. I tried also to load the C64 versions (on the C64) but with the same result :( . I tested normal and "inverted" waveforms, but nothing seemed to work. I was only able to ...

Re: a Maze generator program
I'd presume a guard (facing to the east like thus: >) would also miss out on an occasion like this: | | <-- unreachable corridor | ... --->---+------- if the maze follows the rule I described, that corridor will be visited from North to South when the guard comes back from its route. I can't prove ...

Re: vic20-emu (another emulator)
A small update: the emulator now accepts the "?load=url" querystring parameter where "url" is any external URL that points to a VIC20 .prg file. This way you can load programs that are hosted externally. E.g.: https://nippur72.github.io/vic20-emu/?joy=1&load=http://www.zimmer...

Re: a Maze generator program
reviving this very old thread.... I am still thinking about a maze generator, now for a possible III episode of Raid On Fort Knox. The maze generation has a restriction though: in ROFK the "guards" always move forward, turning left or right only when they bump into a wall (either a 90 deg ...

Re: Putting a VIC program into a QR code
another issue is that you can't call fetch() from an HTTPS domain (emulator) into a HTTP (without the "S") one like sleepingelephant.com
