Troubleshooting:
I will try to cover as most problems PM has on install here, but I can't have a question and answer for every single problem, if your problem is not posted here, feel free to join us at the IRC (
http://irc.lc/gamesurge/projectm), I normally frequent here but other members may help you out, just drop by for a question, to thank me, or to say hello!
Before reading or asking for help, read this:
1. Most of the fixes to PM are just to re-format your SD and to re-download (make sure your SDCard isn't PNY for hackless method).
2. It is recommended you delete all stages that you have on your game, even the ones Brawl comes included with.
3. SDHC cards don't work with hackless.
4. It has been noted that really old Wii's (really, really old) need to be updated to latest version to work with PM.
5. Make sure you extract the downloaded .zips to a folder, open that folder and copy everything inside to the root of your SD Card, if you're a homebrew user, it will ask you if you want to replace files, hit yes and proceed with installation.
