Regarding the support for SFIII-2nd I have tried to creat a new version of MAME that will just 'printf' each address (PC) that is being executed by the SH2 but I I can't get to have them all printed out.
For that reason and following Alex's proposition. I'm asking for support of the experts around there to provide new C files that need to be changed in order to get printed all the addresses that are executed. An improved version should ideally generate a table that sets to one te value of an address if it was exectued, so we avoid getting laaaarge output files. This is not critical, as a little script in Notepad++ could do the job.
