    Windows XP (x86) would be fine, it's just that x64 OSsesesssess don't support 16bit stuff anymore.

    You need an OS that can cope with 16-bit code. XP 32, basically.

    For the original BINHACK to work you'd need, XP 32bit, Vista 32bit or Win7 32bit. As long as it's not 64bits.

    However using my binhack32 clone this limitaion is removed: http://shenmuesubs.sourceforge.net/rsrc/download/addons/binhack32_1.0.0.1-Win32_Linux.zip

    And by doing what I told you earlier in this thread, you can use my pack on 64 bit Windows with no problem, you only have to create the hacked bootsector (ip.hak aka hacked ip.bin) by hand.

    The TuxTheWise tutorial is good for audio/data backups. But for games with no cdda tracks, this is not optimal. The optimal way in this case is data/data 45000LBA, which my pack does. It makes hacking most games unneeded as the TOC is at the original LBA.

    Again, I offer to make the image for you guys if you want, my selfboot setup is always ready and I could do this pretty fast I think.

    Cheers,

    I've been making a day of it and got 18 Wheeler, Cannon Spike, Charge'N Blast, Crazy Taxi 2, Daytona USA 2001, Death Crimson OX, Dynamite Cop, F355 Challenge, Fighting Vipers 2, Industrial Spy, Planet Ring, Power Stone, Power Stone 2, Red Dog, Sega Marine Fishing, Sonic Shuffle , TimeStalkers, Virtua Athlete 2K, Virtua Striker 2 ver.2000.1 and Zombie Revenge all working flawlessly on CD-R on a retail DC.

    The only 3 track games which haven't worked thus far are Confidential Mission, Outtrigger and Rez - they crash the emulator and go back to menu upon booting, but given as they are some of the last first party games released I'm guessing it is due to some form of additional copy protection.

    Bomberman Online has also been a bitch but that is only because I don't want to downsample anything - it is on my to do list before I start to play with 5+ tracks/CDDA. Given the choice though I'd rather not downsample it at all and get me a 90 or 99 min CD-R, though I need the practice so =/

    Overall with a little help from family guy and google it only took me a dozen coasters to finally get it bang on :p

    EDIT: The King of Fighters Evolution kept RSODing, Heavy Metal Geomatrix and Marvel vs. Capcom 2 display the 50/60Hz select but the signal drops if you do anything. I swapped out my VGA box for my RGB SCART and they booted NP - I guess some games just can't be forced =/

    Eureka! I just had my first success (with more than enough notes to be [in theory at least] perfectly reproducable and automated) at making a .gdi I ripped selfbootable (with CDDA).
    The cool thing is my method works without multiple separate burns and with Win 7 x64 :)

    I'm currently trying to work out the last few things (or so I hope) I'm not quite sure about and will then either post a detailed tutorial or - what I'd prefer - a one click tool to do all the nasty stuff, that might take a few days though.

    Oh, and I definitely need to do more tests with other games but I'm pretty confident right now.

    EDIT: So far I tried Quake 3, Trickstyle and Sega WWS 2000, all worked on 1st try on real hardware (once I had a rough idea wtf I was doing) :)

    @FG: Could you link me to those? All I could find was crap that doesn't work in modern OS's (and your packs which I had no luck with either, and please don't take that as critique or whatever, I don't honestly give a fuck what anyone else does or has done or is planning to do, be my guest, if I don't have to waste any more time on this stuff I would not mind that at all, I'm just trying to help).

    Automating both data/data and audio/data has already been done for "normal" games.

    The Graal would be a method to create a CDI image without burning, nor mounting in daemon tools, for most games. With automated dummying, sorting and cracking of some non-lba copy protection it'd rock! I might give it a try in C++ if I have free time one day ...

    Cheers,

    You know, all this time I've had your batch file I never knew it allowed for a list order and dummying etc. I guess I should have grabbed one with a readme, or at least snooped around a little, heh. Kudos on the pack, and cheers for the instructions!

    I believe XP can run the 16bit executables?

    also just out of curiosity familyguy, 'why' is the nrg being produced unusable? seems kinda silly to generate a file that can't even be used without additional conversion

    It's barely "legal" in the nrg standard. Some old versions of nero supported it, but not all the time.

    Its use it to test on emulators prior to burning. It avoids buying cd-r and wasting time. You could also simply burns the 2 tracks it makes.
