Please note that there are a lot of active vic user with a full memory expansion too: Ultimate Expander, Final Expansion, Mega-Cart for example
So 16/24k game with some data on BLK5 is not a big problem in these days
Should I develop for tape or disk or both?

Prefer disk.

Mega-Cart: the cartridge you plug in once and for all.
You could make a game which sequentially loads "endless" amounts of data. If you use a tape turbo that is at least 5X regular transfer rate, you could fit about 300 kB per side on a C60. That should not be impossible to do.
If you can get ahold of a tape turbo that loads at 10X without errors and combine with C90 media, I believe you could cram in 900K per side. That is more than five sides of a floppy disk. Imagine a VIC-20 mega game that has some 500-700K of sequentially loading game data.
Yes, the difference between a tape turbo and a disk turbo is that while both make loading faster, the tape turbo will also use less magnetic media so you can store a lot more on the same amount of tape.

Do you need a Turbo-Tape ?
Take a look to my Turbo-Tape 2.0, it is included on Mega-Cart and when you have turbo-saved programs or datas you don't need it for turbo-loading.
You may turbo-save your programs with Turbo-Tape 2.0 and users do not need it for turbo-loading your program, just LOAD with a normal Vic without any tool.
For example, this is the tap file of the turbo-taped version of Tetris+ for Vics+3K, if you try it on Vice you may see that it takes about 10 seconds for loading.

I don't know about you guys, but I think the stringy drive is the wave of the future:

Normal kernal routines writes the program to the tape many times while turbo-tapes simple write programs once, so you need good tapes if you think to preserve it.Jeff-20 wrote:how exactly does this work? How does

TurboTape 2.0 code is based on Compute!s gazette TurboTape (July 1985 - Issue 25, Vol. 3, No. 7), after Fixed by DR. B. v1.2 there is a full detail of a first version published on ISSUE 56 / JANUARY 1985 / PAGE 124.
My version allows to speed-up any vic program for any memory configuration and unexpanded program that uses all 3.5kb.

Twice, to be exact. The copy is there to check whether it is identical to the original. Otherwise a ?LOAD ERROR results. Errors can only be detected with this scheme, but not corrected.nbla000 wrote:Normal kernal routines writes the program to the tape many times while ...
The turbo-tapes also use an own, faster, signal modulation. This really doesn't pose any problems regarding signal quality, as the highest frequencies involved are still lower than, say, 4 kHz - while a good tape makes good recordings at 8 kHz, or more.
More important is the resilience against different recording speeds. Whether a slow tape read back on a fast tape works, and vice versa, sorts out good tape speeders from bad ones. Tape speeds can differ by 10%.
