Here is another conversation of Stepmania for the PSP made in Lua. This one is by Joreofiorio35. Release notes:

Hi, this is my Stepmania Port for PSP. I have been working on this for the past couple weeks because I needed something like this for the psp. Only seconds after I posted version one, someone had P.M’ed me that he was making his own DDR for the PSP that would read DWI’s and SM files, etc. Then I knew I could stop working, his would be way better than mine! But for fun I continued and this is what I have so far, so thanks for trying this out! Version 2.0 Supports the Following:

  • DWI FILES
  • BACKGROUNDS
  • BANNERS
  • 4th-192nd Notes
  • MODS
  • ASSIST TRICKS
  • COMBOS
  • COLORED ARROWS
  • SONG SELECTOR
