I am unable to check the RAW WRITE box and I'm unable to do anything under method. I got everything up to that point. Is there something I'm doing wrong?

Thanks

I DL'ed the new version and the option shows up. The only problem is that I can't adjust the burn speed any lower then 16x. Also I noticed the image is over 700 MB I'm guessing that what discjuggler does right? It kinda shrinks it down to the 700 mb cd-r?

The demo that on the main site didn't work for you? Your drive may not be recognized by it, I suppose. The old trial limits your burning speed to the lowest available on your drive, and I imagine the new demos are the same way. If you're seeing 16x, that means it's the lowest speed your drive supports. If you burn the disc and your Dreamcast can't read it, you'll have to buy an old DVD-R drive on eBay or something that supports burning slower. The Dreamcast generally doesn't like discs burned at high speeds, but you may not have any problems if your Dreamcast likes you. Wink

I actually got it to work on the newer version. What I did was go to the options and put write speed at 4x and when. So when I went to burn and change speeds it only burned at 4x and didn't need to mess with the speed under method. I tested the game out and it worked but did it all fit on the disc seeing as the image is over 700 mb?

You selected mode 2 right? If so, then everything fit. Why? Well, if you really want to know...

Spoiler:
That's the point of mode 2; it eliminates much of the error correction and allows that space to be used for user data instead. A CD has 2536 bytes per sector, all of which get used for user data in audio mode (giving an 80-minute CD a storage capacity of around 800 MB). In data mode 1, only 2048 bytes per sector get used for user data, and the other bytes are used for extra error correction (so if you scratch the CD, you can still use it), and that reduces the storage capacity of the same 80-minute CD to around 700 MB. Burning in mode 2 changes that so 2336 bytes per sector get used for user data, which again raises the storage capacity to be closer to 800MB, at the expense of reliability. AFAIK, GD-ROM uses similar techniques; the extra storage capacity is partially achieved through eliminating almost all error correction, which is why Dreamcast discs are so finnicky. If you scratch them, they don't work anymore since their capacity requires that they have little error correction, as well as extremely tightly packed sectors, much like the "turbo" CD-Rs that have 900MB capacity and can't be read or written by most drives.

I gotta admit that was very informative Ives. That cleared things up perfectly. Thanks for all the help and patience. I got the game burned and started playing today. Now I just have to get some money for a BBA Sad

No need for a BBA. The game plays perfectly well using a dial-up connection. Now where to get one of those... Actually if you get high speed from an ISP like maybe AOL, they will give you 10 hours of dial-up per month for free as emergency back-up, so you don't have to pay extra for the dial-up.

AOL dialup doesn't work... I tried... Too bad they're like the only company that still specializes in dialup...
(But I may have found a workaround--I just got a bba when I thought of it...)

There's a trick on youtube that works with Juno dialup ISP (10hrs a month)--http://www.youtube.com/watch?v=Iw5kWM_UA-Ak.
You'll need to find a non-virus infected dialguard though. I don't know if I still have my copy around here somewhere...
