VIC20, its graphics, features

Hi!
I'm here new. I'm really 128er and TED Series fan, M65 user.
Few weeks ago I bought MiST FPGA and downloaded VIC20 core - I know, everybody of you can tell "That's not VIC20!" - yes, true, but before this I knew about VIC20 near nothing.
Experiments uncovering me VIC20 features, never known graphic possibilities and other. It makes for me VIC20 like it is on adverts "friendly computer".
I found also anything unbelievable - VIN20 GUI for VIC20... Yes, VIC can graphics...
VIC20 core allows load PRG files and mount CRT images only.
For this reason I'm searching for these CRT:
Basic V4
Basic V5
JiffYDOS
Minigrafik
Especially Minigrafik for Mandelbrot test.
I created blog about Mandelbrot tests between Commodore computers (http://cbmandelbrot.blogspot.sk) and found Basic program for VIC20 which I adjusted to compare with other computers. But this program requires Minigrafik.
I can load and run Minigrafik and then load Basic program, but there is other starting address and its behavior is different in two ways:
1. When I paste program to VICE emulator without loaded Minigrafik and save it - then is program in Minigrafik on MiST core invisible.
2. When I paste program to VICE emulator with loaded and running Minigrafik and save it - then program displays mismatch at list and syntax errors at start on MiST core.
So, no way, only Minigrafik CRT image...
If exist please write link, I do mandelbrot test and it will be possible to compare to others.
Thank you for all.
