The ROM Hack isn't on the site yet? By filling out this form you can request that game to be added on the series. Before filling out the form please have a look to the guidelines in order to have your request accepted:

A video of you running the ROM Hack is mandatory and it has to be a full game run. (ex. an Any% run). Individual Level runs will not be enough to add a game.
You need to have the speedrun.com 2FA enabled on your SRC account in order to be added as a moderator on the ROM Hack you are requesting. (Go to your settings and you can enable that option in the "Account" tab)
The ROM Hack you are requesting must be notable for speedrunning by having a least a few levels in it. Single level ROM Hacks will not be added on the series.
The ROM Hack must have different levels than the original game or they must be edited in some way (a level randomizer is fine for example), a ROM Hack with Mario, Bowser or whatever character replaced by another sprite aren't accepted.
Requesting unreleased ROM Hacks are possible but they'll be added only up to 7 days prior the release date. There's no need to add a leaderboard if we don't know when the ROM Hack will release or if it's in a few weeks/months. If you are requesting an unreleased ROM Hack you can send the trailer as the "Run URL" with all the other necessary information. I may ask further information by contacting you.
It would be highly apprecitated that you include some stuff about the ROM Hack you are requesting so I can see what the ROM Hack is about such as the trailer, an info page concerning the hack etc...

If your request is accepted you'll be granted "Super Moderator" privileges on the game you requested and you'll be able to setup the game as you wish*. If you need help for moderation you can always contact me on Discord, Twitter or with a SRC direct message.

*Please note that I reserve the right to not grant you Super Moderator privileges immediately depending of multiple factors (such as but not limited to: behavior on/off site, site/moderator activity ect...), those privileges are pretty huge so they need to be used with care and I have to be sure that you'll be a little active at moderating the ROM Hack.
