Tip: Take advantage of easy to install Patches in your hack. The No More Sprite Tile Limits or SA-1 patches should be considered if you're encountering glitches where Mario and/or sprites are turning invisible.
I'm sorry I haven't been updated about this website as college as a serious toll on me. My question why has there been such a lack of hack uploads lately? Is it something I'm not aware of or simply members aren't uploading them?
Are you sure you're checking the right section? At the current time of writing the hacks waiting to be moderated section has 63 hacks waiting to be moderated ranging from the dates of 2013-06-27 to 2013-12-05.
To add to that, if I remember correctly the hacks section is still going under re-moderation because they are cleaning things up a bit.
There are a lot of things that need to be remoderated. Every staff membeer has his specific work (some are moderating GFX, some hacks, some music, etc.). I think that's the reason why some new people have been promoted to Staff and now they help to make things easier.
