A couple of days ago, homebrew coder ufo_z came up with the unofficial demo version of the video game Cave Story. We say unofficial because Variant Interactive last year mentioned that it is planning to port this freeware PC sidescrolling adventure title to the PlayStation Portable.

Despite that, we think that ufo_z's take on the project somewhat holds more water as the developer has gotten the approval of Cave Story owner Daisuke Amaya (Pixel). Anyway, this is the second demo released and a lot of improvements have been implemented since the last version.

ufo_z wasn't able to include a changelog for Cave Story PSP Release Candidate 1 but the following reminders were provided:

* Firmware 1.0: should work with no modification
* Firmware 1.5: needs kxploiting
* Custom firmware: (3.xx OE): should work with no modification; goes in the GAME150 folder
* Game saves: works with saves from the windows version; filename needs to be Profile.dat (case sensitive); (same for 290.rec)
