Xeal's Trackmerge.
 

Do you use this program on the cdi file over and over until it gets down to one audio file in the first session? because if I only use it once it only brings it down to 8 audio files. You need no more than one audio file in the first session to use the Buffer Under-run solution. I noticed if you keep using it on the cdi repeatedly it will get down to one audio file. Is this the correct way to do this?

no, it's pretty much designed for the games where the first or second track is less than 4 seconds

it does the exact same thing as the patches I made for super runabout and 4x4 evo

for example, in 4x4 evo the first track is 4 seconds, and the second is 2 seconds

many burners cannot burn the 2 second track

you run trackmerge on the cdi once, it deletes the second track and makes the first one larger to compensate
