Let's find a way to replace Sega-games in SEGA Collections
That is what we have:
Game "Sonic Mega Collection +"
Here on game's DVD in mdrom directories there are files.CPT placed here. These files.CPT is (as i think) an encrypted archives.CPT with packed Sega ROMs inside.
Again, as i think these files were encrypt with ccrypt program. If it true, then one can download and install ccrypt and try to unpack one of these files by command line in linux:
ccrypt -d SONIC3.CPT -K >password<
One programmer should try to write a script (something like brute force) which search for password.
It is unknown really it an encrypted cpt-archive or not, a size of password's word and which symbols are used.
Game "SEGA Genesis Collection"
Here on game's DVD in directories A-...-Z there are files.ELF placed here. These files.ELF is a binary files, BUT i think it is some kind of archives.
Original Sony's toolchain (exactly objdump) recognize these elfs and it can to disassemble it. We need to extract files from elfs for replacing Sega-roms! Is it possible?
I asking all the answerings do not write in this thread about pgen or "Let's wait until ragnarok (for example:)) will build new emul for us". You should to concentrate on targets above.
