I have made practice saves for all chapters in any%, as well as saves for bosses/certain skips. Included in the drive link is also a guide for installing these saves, and DLs for Savegame Manager GX.

These saves were made on NTSC version 1.0, and I don't know for sure if it'll work on other versions, but feel free to try it out.
