This is because the exec.library inside the CDTV ROM has been modified to also scan the $E00000-$E7ffff area for ROM tags. If you use Kickstart 3+ then resident modules on the memory card will not get initialized. CDTV 2.35 + Kickstart 1.3 or Kickstart 2.x.If you're not using 1.0, 2.0 or 2.35, and have verified reading/writing RAM works fine, then the problem may lay with how AllocRamDisk / vice works, but I haven't used those tools, so can't really comment much there atm.Īlso note: any resident modules on the memory card will only get initialized with the following combinations of CDTV/Kickstart ROM: (Let me know if you need help with that.) Then you can use any memory from $E000002 and up freely without it getting wiped after reboots. So if your system has 1.0, 2.0 or 2.35, you need to make sure to write "OK", "RD" or "RW" to address $E00000 once before use. (It is missing from 2.7 and 2.30, because those ROMs contain portions of code that were built for the A570 and that hardware doesn't support memory cards). vice is present in the official 1.0 ROM, the 2.0 ROM and the unofficial/custom 2.35 ROM.
