Download 9 is a collection of patches made by myself (meleemario) using Sappharad's [MultiPatch][5] (version 1.3, 32-bit) on Mac OS X 10.4.11 Tiger) utility. Patches for Cave Story 0.0.6 in English, 0.0.7 in both English and Spanish are included in IPS, UPS, and XDelta format. To apply these patches, first install an untouched copy of "Doukutsu.app" (either 0.0.6 or 0.0.7) to the Applications directory, then run MultiPatch, pick your patch format of choice (Whichever you are most comfortable with), and point it to the unmodified application, and you should be all set. I haven't tested these patches myself though, only created them, so do let me know how they work in the comments!
