iq_132:
The code for fba is a little more complex because of the bankswitch being used.
It seems everyone is using different names and versions of the code.  I'm posting
what I have; you may have to edit it a bit to make it work for you.

My fba compiling error..
I need NeoPVCScan source... Anyone know this?

iq_132:

--- Code: ---unsigned char *NeoCartRAM = (unsigned char*)CartRAM;

int NeoPVCScan(int nAction, int* /*pnMin*/)
{
struct BurnArea ba;

if (nAction & ACB_MEMORY_RAM) {
ba.Data = NeoCartRAM;
ba.nLen = 0x00002000;
ba.nAddress = 0;
ba.szName = "Neo-PVC 68K RAM";
BurnAcb(&ba);
}

return 0;
}

--- End code ---

Thanks!! IQ_132~  :biggrin:
