Chiip v0.9.1 is now available in the Download section.

It's yet another test version. The last stable version stays Beta 5, but I expect it to work quite fine.

Changes to v0.9.0:

  • No bitsetting required
    This means that more or less all DVD+R/+RW/-RW discs should work now
  • The "reduce DVD speed by quitting and restarting a game"-trick was removed from this version; I will soon add a different way of setting the speed
  • Might improve support for different region originals
  • Again changed the login process a little
  • The Linux and Wiip-AT90S2313 versions were removed from this release as it's only a test release anyway

Please fill out the v0.9.1 survey if you have tested this version!

Be extremely careful with Wii import games that try to update the firmware - they may brick your Wii! I know that at least a few PAL users have bricked their Wii by trying to run the new Super Paper Mario NTSC version on a PAL Wii with old Wii firmware (< 2.1E). This will produce a screen like seen here. This of course applies to all current Wii modchips, not just Chiip. You should generally be very very careful with games that require a firmware update before they will run - but this is extremely critical if it's an import game, because it might try to install a different region Wii firmware! (As for Super Paper Mario, it seems to work on PAL Wii if version 2.1E was already installed - but I'd still be very very careful, as even on 2.1E PAL Wii the firmware update dialogs appear and seem to do something, and nobody really knows what!)

A few people have reported that blinkcode SSSSSLSS occurs if the Wii is turned on with a disc already in the drive. I cannot reproduce that bug on my Wii, it works fine here. If you've experienced that bug and would like to help fixing it, please send a mail to chiip(AT)trashmail(DOT)net and tell me your DVD controller chipset and the region of your Wii. I will then send you 2-3 versions for testing if the bug still occurs.

If you've already tested the new version v0.9.0, please provide some feedback by answering a few questions in this short, web-based v0.9.0 survey.

Chiip v0.9.0 is now available in the Download section.

First of all: This is a yet another test version, the last stable version stays Beta 5. I hope this will be the last version before the 1.0.0 release, but I really need some feedback on how it works, so please test it and fill out the survey on the 0.9.0 release that I will publish soon. What I'm most interested in knowing is if the Wii region patching works on NTSC USA and NTSC Japan consoles, because I modified the usual Wii region free patching a bit and I wonder if it will work on USA and Japan Wii too.

Changes to beta 7:

  • Wii and Gamecube region free. While region free should work fine for all Gamecube backups, it only works on some Wii backups. This is a problem all current Wii modchips have, which is why you'll always read of "partial region free". There's a great page in the gbatemp Wiki that lists which games work and which won't:
    http://wiki.gbatemp.net/index.php/Wii_Region_Free_Patcher_Compatibility_List
  • Changed the version numbering. This might be a bit confusing, but I hope that the 1.0.0 release will be available within 2-3 days, which should stop the confusion
  • Gamecube originals should work again
  • Changed the login process a little. You should now be able to reduce the speed of Wii originals too, by using the "Start game then return to Wii menu" trick:
    If you insert a disc it will run at maximum speed, but if you start the game and return to the Wii menu the disc should slow down
  • Included Linux and Wiip-AT90S2313 versions. The Wiip version is completely untested, and just included if someone wants to give it a try. The Linux version requires ppdev and a DVDTool-compatible cable. There will be a Windows compatible version as well soon.
  • Maybe something else that I've forgotten

You will have to flash the right version for your region (NTSC Japan / NTSC USA / PAL), otherwise nothing will work. Maybe I will switch to using a setup disc too sometime, but for now I think most people will prefer this solution.

To flash the firmware, use the following commands:

For NTSC Japan:

avrdude -p m8 -c sp12 -U flash:w:chiip-0_9_0-atmega8-japan.hex -U lfuse:w:0xE3:m -v

For NTSC USA:

avrdude -p m8 -c sp12 -U flash:w:chiip-0_9_0-atmega8-usa.hex -U lfuse:w:0xE3:m -v

For PAL:

avrdude -p m8 -c sp12 -U flash:w:chiip-0_9_0-atmega8-pal.hex -U lfuse:w:0xE3:m -v
