You (or Eero) replied me that to let the TT-ram work, there's all hatari to=
 parse again to be sure that all the addresses of all the hardware componen=
ts are encoded in 32 bits in all the *.c functions (and *-.h).

So, if any part of hatari uses 24 bits hardware variables, memory search or=
 filling, ... it wouldn't work correctly.

Objet: [hatari-devel] add support for TT ram ?


I see that in memory.c code is almost there to handle more ram at=20
0x01000000 , as provided on TT for example when using 32 bit addressing.

Only missing parts seem to be an option in the UI and some command line=20
parameters (--tt-ramsize for example).

To use such ram, the cpu needs to use 32-bit addressing mode (--addr24=20
false), but apart from that it should work with >=3D 68020.

Is there any reason why it was not enabled so far ?
