Awesome! Automatic ripping is what really makes a format thrive.

Progress was made yesterday.

Stuff that's still needed to be done:
- test file loading
- make 68K CPU stops when Z80 dumps are being played
- implement 32X and Sega CD support
- test Sonic when no rom is present(data is loaded to Z80 before playback)

Even though Gens is GPL licensed, I refuse to use the license equivilent of AIDS, so I will just release the dumper/loader code seperately from Gens so that any emulator can go ahead and use it.

UF, maybe you should try going through some of the drivers listed here: http://gdri.smspower.org/wiki/index.php/Mega_Drive/Genesis_Sound_Engine_List

And see if this Z80 dumping thingy doesn't by some chance work with only one or two drivers.

Sonic the Hedgehog isn't going to work with this format as it is.

Which is no big loss, Sonic 2's music was much better.

Dynamite Headdy, on the other hand, does not work. Dammit.

___

Here are the header formats now. As you can see, there is some support for the 68000, which will be better as the format will be able to support ripped data.


Header Type MDZ: Type identifier

struct {
char Magic_Word = { 'M', 'D', 'Z', };
char Version;
}

Header Type Z80: State of the Z80 audio processor

struct {
char Magic_Word = { 'Z', '8', '0', };
// register map goes here.
}

Header Type PRG: Program section

struct {
char Magic_Word = { 'P', 'R', 'G', };
int CPU_Type; // 0 = Z80, 1 = 68000 (Sega CD), 2 = SH2 (32X)
unsigned int length;

char * data;

}

Header Type 68I: 68000 initialization section
Data is loaded by DAT (see below)

struct {
unsigned int Init_Addr;
unsigned int Play_Addr; // call this to keep stuff going

unsigned int ByteToChange; // Location of a byte that helps set a song code
unsigned int BytesNewValue; // changes the byte at BytesToChange to this given value

}

Header Type DAT: Data bank

struct {

char Magic_Word = { 'D', 'A', 'T', };

// load addr is 68000 memory!
unsigned int load_addr;
unsigned int length;

};

There are quite a few errors above so disregard it for now, and get on IRC if you want the full details.

2sf revisited by unknownfile at 11:48 AM EST on December 8, 2007
Time to go back to old times when I was still working on 2sf.

I pulled out a 2sf test, and it seems like everything is working, even on my new PC.

Expect some progress by next Octember.

You still want me to spread your word around looking for programmers for your 2SF format?

Most people don't understand that 2SF is stupid anyways.

kingshriek has 5 new SSF rips up. I still wish that there was a Winamp port of his SSF plugin.

Get them now.
