I don't really know if there's a way to test them... except playing online against somebody for testing if they work online, or maybe have an old File Replacement code in the RSBE01.gct file.
Is there maybe a topic that states all the things you need to do before you upload something and how to test stuff to make sure it works? And all the things I have to test first to meet the standarts of this page?
For an example, I've "made" an character who is really invisible when I play her and play against her, with no freezes, and I thaught it would be kinda nice to have a character like that to take some pictures like...
a character holding "nothing",
a character floating because an invisible character is holding him,
getting hit by nothing,
effects when you hit "nothing" (invisible vs invisible),
and more.
Here's a video to that character. Works fine with me. Not in the invisble Zelda version though, when I roll around, my character gives out long lines and make the game freeze. =/ Oh and don't judge me on that video, I haven't played for several months. oO Tested yes, acutally played no. xD
I want to upload more than that but before I do, I just want to know what I need to know, so I'm allowed to load it up. ^^
