Several bugfixes for 3DS port of SDL

[sergiou87]

Hello!

While I'm working on porting my Supaplex reimplementation to 3DS I found a bunch of bugs in the SDL port that I have fixed.

I saw I couldn't submit PRs to the devkitPro repo, so I submitted it to my own fork hoping someone could take a look and help me merge it to the official repo.

The PR is here: https://github.com/sergiou87/pacman-packages/pull/1

Thanks in advance!

Nice work, thanks for taking the time to PR your changes.

I've updated the patch in the package and rolled an update now so it's available for everyone.

Happy to help! And thanks for the quick update. Now I can use the official package again ^_^

BTW I submitted another small PR because it seems I left something there, sorry!
