    Hardware Donations
    If you've some old SNES hardware that you want to get rid off, and that you want to donate for emulation and research purposes, some things that I am looking for would be:

  • Naki/Fire Tribal tap (five-player adaptor, the thing has 5 connectors, but only 4 seem to be working)
  • A snes mouse (for testing it's sensitivity/threshold)
  • BSX-Flashcart (mini-flashcart for BSX games)
  • Nintendo Power-Flashcart (big-flashcart with unknown access protocol)
  • Photos of different Hudson (and third-party) Multitap PCBs (don't need to have the real hardware, but would be nice to see what is in there).

    • Aside from SNES hardware, some other stuff that I am currently looking for:
  • Nintendo DSi (or DSi XL, or 3DS) handheld console (region is don't care)
  • Nintendo DSi (or 3DS) game cartridge (region is don't care)

    • Note: shipping address would be in germany. For email/contact, see below.

    If you like no$sns, please donate some money, this will help me to continue to work on emulation projects.

    Features

    (on 1GHz computers, most games can run 5-10 times faster as on real hardware).

    • Known Problems

  • Interlace Mode (vertical hires) isn't yet supported (used only by 3 games or so)
  • Offset-Per-Tile Mode isn't yet supported (used by Starfox... and probably by some further games...?)
  • GUIs of Copiers and Cheat Devices should be working (but without actually emulating FDDs or Patches)
