=== Alternative solution - Disc Merge === | === Alternative solution - Disc Merge === | ||
Alternatively ps1 discs can be merged into single bin/cue. There could be potential limitations in file size because MM:SS:FF can only go up to 99:99:99 which translates to around 870MB. For sure this will be problem for games with CDDA tracks. For now there is no confirmation that this limit apply to data only games. How hard is disc merging depends highly on game we want to use. Parasite Eve is one of easiest games to do that since second disc check is triggered only if files from disc 2 are not present on current disc, which they are since discs are merged. Game also use the same EXE and PE file on both discs, and do not use lba based tables. So merging discs is literally repacking them into single disc. But different games use different approaches, games like MGS need additional patches to few files to skip shell open checks, and lba adjustments.
