omg,thank you soo much for the reply's soo quickly !!!
I will follow again the steps from the start and i will do the sort step twice as described and also use your ip.bin,the steps i had taken were the same as these in the tutorial on this thread,once i had fixediso,it gave me a padding file,fixediso and a bootfile that i renamed to IP.BIN and i placed this in the c\discroot folder as described,this was done on thew windows xp and win7 tests yet it never ever found the ip and would also ask for the binary,i am guessing now that the ip has the title name and descriptor in it and without it,its asking to create an ip and a title,i just dont know why it won't find the ip either with or without caps.
Also many thanks for the info on the wave files,i will now check them over by extracting from the afs and see if they sound ok !
The last thing and this is where i had thought i had went wrong,was the s01t01.bin,am i correct in thinking that this bin along with both cue files for s01t01.bin and s02t02.bin should all be disregarded and deleted ? i ask this as like before i could never find a real answer to this but also that i found 201t01.bin to have files on it,it wasn't merely a dummy file however when i explore it,it does in fact look like a bunch of the exact same files that are also in the second bin file with all the data,basically a few folders for www addresses and a data folder and i think the games movie intro file is on this track but again,i checked s02t02.bin and all these files are on track 2 and are all same file size.
yes i am using nulldc,i can load the untouched cdi no problem,it's just after i extract and compile with any method before i get to the sega screen or the cd player screen,i did use some discs to see if it at least worked apart from the selfboot side of it using the boot loader but none worked.
many many thanks,it's really appreciated
EDIT --
I tried using the supplied IP and doing the steps over again,when following the steps i am asked to do the sort file twice however i think this is because i am asked to make a sort file before any changing of the iso and then at the end asked again as i have made changes but because my extracted iso has the files replaced before i begin,this means that the fist time i make the sortfile,it's reflected with the new audio file sizes as seen in the sortfile when i look through it
my question would be,must i make a sort file "before" i make any changes and if so then why when i am only going to make another newer one with the changes to the audio files,i ask as this is the only step that i can see a possible problem yet i wouldn't think this to be an issue but i could be ... i say this as i used the ip.bin provided and then went through the steps with the sort file again and again when i get to the bin2boot,it still tells me there is no ip and if i would like to create one,also i manually went over the sortfile to look for any errors or clues as i think the sortfile to my understanding works a bit like a cue file ? it lists all files and file sizes,this along with the dummy fools the dreamcast into thinking the file size of the game matches the orginal otherwise no boot,i dont know if i am right but this would make sense.
since i used the provided ip,i now DO get past the sega logo but then a black screen and quickly goes to the cd player,it's as if its trying to load the intro movie to the game,in nulldc i get SPI unknown,googled this and it seems to have something to do with wince or the console type boot,this cdi that normally does boot had come up as a ketana type,i remember as i was asked at some point if i wanted to convert and scramble it,since that time i have reverted back to working with the normal working cdi/extracting and trying to recompile.
this is as much info as i can think of,i don't know what i am doing wrong,it's clearly my error somewhere
EDIT - 2
Ok,i found that the problem with creating the cdi in bin2boot was that i was using the code supplied wrong ..
mkisofs -C 0,11702 -V MODDED_CDI -sort output.txt -l -o new.iso c:\discroot
this part (11702) should have been changed to my own lba of 45000
after this,and going through the usual steps it then made a cdi image however it's not working,as i had expected in some weird way,it now boots up to a black screen and crashes in nulldc,i am yet to try and burn the cdi,it's as if it's looking for the intro movie and crashes,this intro movie is located in track01 as well as track 02,it makes me wonder if i should be trying to include track01 when i build this image ? also there is one thing that i had noticed way before i even started trying to compile,it's when i was looking through the games audio tracks,i found that every single audio track would play however,the audio track that plays when the game starts (the audio that may well be playing over a silent movie track) this audio would NOT transfer over,it would not extract,it would say it was corrupt,this was from the games tokyo asf,the tokyo file has the usual audio but also all the frontend and menu stuff,this audio track does play fine on the dreamcast but will not extract out of the hundreds of audio that do extract,makes me wonder.
also to note,at the stage where i was making a dummy file in bootdreams,i exit before actually making the image,bootdreams had asked me again,telling me it was a ketana image and also if i wanted to scramble,i said no to both and ext before making the image,i don't know if this has anything to do with it booting up,i would love to know if this crash could have anything to do with the modded music,i will now extract and recompile the cdi without making any changes to the game to see if then boots,if so then there is an issue with the audio files im using or the sortlist file sizes,i have modded soo many things over the years,done lots of saturn stuff and rom hacks and so on but the dreamcast is a pain in the ass !!!
had a look at the image in disc juggler and it complains its too large for 1 cd,the audio i hacked in is a little smaller than the original files in total,i don't know why the outputting image ends up larger.
so far,i think i now know how to extract,convert and compile but as of now,a black screen at boot
