SM64 ROM Manager (Info & Download)
SM64 ROM Manager
Developed by Pilzinsel64


The SM64 ROM Manager is a brand new all-in-one tool for SM64 Hacking!
You can create wonderful SM64 Hacks with it. Using the onboard Level Manager, you can create and modify custom levels, edit text using the Text Manager, and many other tools which you can explore yourself!

I've spent a lot my of time in developing this program, which is very limited.

If you want to report a bug or make a feature request, you can either have a look in SM64 ROM Manager at "Help" menu, or you can check my website. There are two links to form that you can fill.

Bug fixes and small improvements I will publish ASAP as small updates (third number of version).
New features comes with big feature updates (second number of version).

Here is a list of things that are already finished:
  • Level Manager
    • Create and remove Levels easily.

FAQ and Information:

"Can I use my SM64 Editor made ROM with this tool?"
It isn't supported and never will be because there are too many bugs to solve in the ROM. Like the N64 compatiblity e.g.

But there is an experimental way to import your levels to a new ROM.
Just open a new ROM and goto "Level Manager". Click the arrow on the left of "New Level" and click "Import Level ..".
Then select your ROM (used by SM64 ROM Manager or SM64 Editor) and import any Custom Level that the ROM Manager is able to read.

"What happens if I edit the levelscript, geolayout or displaylist?"
Nothing. The SM64 ROM Manager reads the edited script and keeps the changes.

Note: After you changed something on the ROM outside the ROM Manager, you need to reload your ROM .

"Where are the Objects/Warps located"?

If the One-0xE-Bank-System is enabled, then the objects and warps are located in the "special" 0xE-Bank. This "special" 0xE-Bank will be loaded at parsing the levelscript and will be cleared at loading the first area. I can do that while the objects and warps will not be needed anymore after loading them. So, we have more space in the levelscript and for the area model, yeah!
If the One-0xE-Bank-System is disabled, then they are located in Bank 0x19 directly in the levelscript.

The One-0xE-Bank System explained:
In the Levelscript is an area table. The levelscript is mainly located in Segmented 0xE. So, the data for the current area is located at 0x19005F00 + AreaID * 0x10. The first four bytes shows the ROM address where the bank 0xE for this area starts. The second four bytes shows the ROM Address where the bank 0xE of this area ends. So, it is like a 0x17 levelscript command, but without the first four bytes of such command. But how do I know that the System is enabled? Easy. Just check the four bytes at 0x19005FFC. If they equal to 0x4BC9189A then the One-0xE-Bank-System is enabled. Otherwise, the 0xE Bank is per Level (as known from the SM64 Editor).

Please note: The One-0xE-Bank-System is not supported in SM64 Editor Levels (in converted ROMs).

"My Textures are offset a bit. Is it a bug?"
No, it isn't. The SM64 ROM Manager does everything right. The problem is your video plugin in your emulator. Many popular plugins does have this bug, such as GLideN64, Glide64, Jabos Direct3D, and some others. The texture is offset a half pixel then. But on a real N64 the textures are on the right place.
Read here an issue on GLideN64 plugin repository.
