- On Risky Ice + Bob
A cooperative crack intro between On Risky Ice and Bob -- two groups whose pairing produced this release catalogued on intros.c64.org. CSDb lists the partnership under group ID 1785, with a dozen entries documenting their joint output -- primarily SEUCK-based games (Shoot-'Em-Up Construction Kit) with +2 trainers, including titles like "Barbarian Jnr.," "Chicago," "King Kong," and "Tiger-Tank." This SEUCK focus indicates the groups specialised in cracking and training homebrew games built with the popular construction kit rather than commercial releases. No individual credits for code, graphics, or music are confirmed for this particular intro. Neither group appears on Doc Snyder's page, Demozoo, or other major archives. Comments on intros.c64.org from Rough (2010) and HBH-ZTH (2008) acknowledge the intro's existence. The full name "On Risky Ice" is characteristically playful -- many C64-era groups chose whimsical names as a form of creative expression rather than opting for the aggressive or technical branding common among larger cracking operations.
