Combine two games in one DVD -problem

I know what I must do to create them(I already made 5 disk's with or more than 3 games on one disk)but I've encounter one problem.I'm trying to place R-Type Final and Grandia Xtreme in one disk and I use DVD Loader v1.2 and here's my problem.

When I create an ISO with only one of the games and place the loader whatever I want the game load just fine but when I place both games inside and the second one that I place isn't working.Does that means that the two games have some kind of protection or I can make them to work.

Does anyone tried to place those two games inside one DVD or place one of them as a second or third game but not first.

It doesn't take much protection to achieve this. Lots of games use fixed LBA tables having the effect that nothing will work if the positions of the files change. Fixing this in making a multiple game disc usually means that you'll have to find the tables and patch them. (One exception is mentioned below.)

Other games use hidden files, so that many of the real files are not even visible in the normal directory, and if you then just copy the visible files you will have missed the main content of the game (without which it probably won't even start). This is an intentional protection measure, and it usually doesn't come alone.

Games using hidden files normally combine that method with the fixed LBA method mentioned above. Squaresoft (nowdays Square-Enix) games nearly always use these methods.

That question is impossible to answer properly without knowing what games you speak of. How then can anyone know if that particular game was placed first or second or whatever...?

But the chance of having a game working is always greatest if it is the first stuff added to a new compilation, since this can allow fixed LBAs to be correct without patching, if you pay close attention to drag-dropping the stuff into the new compilation in correct order. (As seen by inspecting the original ISO in IsoBuster.)

And is there some tool to patch the lba table(Xpert maybe)?

Here's something strange.When I place one of the games first the second won't work,I try all kind of possible correct order of the files of the games but in the end the second one isn't working and the last thing I try was to place all files and folders in a 90% completely random order and??? both games are running.I don't know if the games will be fully playable from the beginning to the end but with that random order both games actually are running.

First I place the main game files of R-Type Final(STR,COMMON,ROOT and SE)and the game elf then I place the music,btl_data,field folders of Grandia Xtreme then all Grandia modules and in the end the R-Type Final MAP folders and for last the DVD Loader.

Both games are running with that ridiculous order?

And here's the final result.I place first the DVD Loader then R-Type Final in the correct file order then Grandia but I place the Movie folder at the end of the disk and now everything is working.The problem was that when I place everything correctly and place Grandia as a second game and if I place the movie folder in his right order the other files and folders after him goes way ahead of they're correct(or close to they're correct)location and the game just don't load,the DVD Loader just restart itself again and again but can't start the game

Thanks anyway,I find a solution myself
