I have a problem with Poseidon 4.4. (With Poseidon 3.8 is exactly the same).
The program will not start. Always gives an error of Ramlib.
I've tried everything. Increase the StackAttack stack, use the MCPramlibpatch ...
The computer is a A4000 with Mediator A4000Di, OS3.9 (blitzkick for load the 3.1 Rom) , Cyberstrom MKII 060 128MB.
But with Poseidon 3.4 everything works fine (unfortunately I do not have the key file.).
