Hello,

yes it does work again, if I simply deactivate the if clause and always
call the memory init values:

/* Write magic values to sysvars to signal valid config */
STMemory_WriteLong(0x420, 0x752019f3);    /* memvalid */
STMemory_WriteLong(0x43a, 0x237698aa);    /* memval2 */
STMemory_WriteLong(0x51a, 0x5555aaaa);    /* memval3 */

Hatari does crash with 4 bombs during the boot sequence if I leave them
out. (Crash happens when it does not find the calvino.ovl file)

Regards,
Matthias
