I added D64 file for C16. I'm pretty sure it works on the SD2IEC
I use CC65 (for VIC-20, Atari, C64 etc.), z88dk (for zx-spectrum, Amstrad, MSX, etc.) C-compilers and emulators. Very decent and easy way to develop new software for old 8-bit machines.
Well.. I wanted to create something like a bitmap mode game for VIC-20 (VIC does not have a real bitmap mode) and I'm a fan of Cauldron II game.
Just tested my drawing routines and added few software sprites. No design plans. :D
I tested it with VICE 3.1 (mac) and it worked ok.
Here few tips:
Configure extra mem (32k or more): Settings -> Resource Inspector.. -> Machine -> RAM -> check all blocks 0-5 -> restart if needed -> VIC-20 Screen shows "28159 bytes free"
Attach D64 disk image : File -> Attach Disk Image -> Unit #8 -> (and select .D64 file)
Load the game : type = LOAD "*",8,1 and type = RUN
