Hi

Make sure you are using a dc_flash.bin that is for the japan region. I had similar problems when initially trying to boot GDI usa games. I eventually figured out my dc_flash.bin, which I copied from my old chankast setup, was for europe.

I made an updated version that can do either the syscall or cdrom_read_sectors methods of reading sub channel data. The 96 byte sub channel data will be appended onto the end of each sector in the track. Transfer speeds for both is still only about 40K/s :? The url for dumping a track now includes a...

You can avoid the flush by reading the data from the non cached region of the memory map.Subcode is stored on an internal buffer on the cdrom , and it is the subcode of the last readed sector.Also note that some parts of the subcode are not 'protected' with ecc so they can have different values bet...

some additional interesting information I found tonight. initializing the cdrom with p being 16 will result in it providing the only subchannel data for what appears to be the previously read sector. With the exception of the subchannel data in the first sector, I was able to get a match when compa...

dreamcast dumper discussion from ug

darcagn/Quzar I want to continue our discussion from ug over here. That'll usually solve it, but that's only because DMA writes require aligned memory (as most everything on the dreamcast does =P). Even with that though, if you want to be safe, I'd reccomend doing a dcache flush on the last 32bytes ...
