Looks like progression to me. Non-working, decoding a sync from flux to MFM, decoding flux to MFM and also to FDC decoded data, and finally booting a disk.AtariZoll wrote:That screenshot with : ... A: ... If it is a hard disk ....
That seems not wise - A can not be hard disk. Unless it is SD card in some HxC or other floppy emulator. But that's not case in Steem .
Usual message by non-accessible hard disk is: Data on the disk in drive C: may be damaged.
So, what's the point with that message ?
Now it's my turn to put screenshotJimDrew wrote:Chessmaster is very protected for the Amiga, C64, and IBM PC. I can not imagine that they released it unprotected for the Atari ST.
Your help is welcome (see my PM).JimDrew wrote:Let me know if you need help on flux<>MFM decoding. I code only in assembly (all CPUs including 68K), so I could lend a hand.
DrCoolZic has detailed info on the WD1772 and some of the state machine functionality. This is something that I am working as well for another project (1581 disk drive emulator).
Yes it worked very well, it loads most gamesJimDrew wrote:You guys are going to be in for a treat!! I just tested the beta Steem and it works amazingly well with .scp images. Don't let Steven fool you, it's working very well for a 1st attempt! I am able to load everything from Psygnosis except Obitus. Dungeon Master (single revolution with "fuzzy bits") works perfectly! Ghostbusters II (NFA), Wizball (Copylock), Fire and Forget, and countless others work just fine.
Nice job!
