The bitmap shouldnt be a problem - you can do that with a charset matrix.
With fully expanded VIC20, porting Elite sounds quite doable to me - still a lot of work, obviously

Re: How to convert Tap files to D64?
Use TapEX -> https://csdb.dk/release/?id=237663
load the tap, select "extract prg" from the menu, and it creates a directory with all files. For vic20 tapes you will probably have a pretty good success rate

Re: Corrupt end of basic program
Yes. However, if there is a reliable way to reproduce this, i'd still like to knowIt is very unlikely that you found a bug in VICE here.

Re: Extremely Rare Ala Software game for C64 - Whiz Kid
I mean (hires) scans, using a scanner, not a camera.

Re: Extremely Rare Ala Software game for C64 - Whiz Kid
Can you do actual scans? The Tape Archive aims for highest quality - i don't think they will accept photos like this

Re: Extremely Rare Ala Software game for C64 - Whiz Kid
OK apparently the original says you should start it with SYS16384 - and that works https://retrocollector.org/photos/full/26259.jpg Attached is a working .tap :) It would be great if you could make hires scans of the tape cover, box, and the cassette itself - then it can be included in the tape arch...

Re: Extremely Rare Ala Software game for C64 - Whiz Kid
OK cool.... first, i can confirm this is this game: https://csdb.dk/release/?id=182936
There is some weird problem with the .tap i produced, the autostart does not work for some reason.... (but the data can be extracted and the game started by jumping to the right address)
Will play around a bit

Re: VICE White Noise Bug?
Sorry, i interpreted wrong what you wrote...
yes it requires "enabled" being zero (for some cycles) to start. which it is after reset.

Re: VICE White Noise Bug?
bit 0 of gate4 is either 0 or 1 on each iteration, and ORed into the LFSR ... so thats how 1 bits go into the LFSR
