N64

Virtual Console

In the case of Nintendo 64 VC, most titles released on Wii appear to use game-specific emulators tailored for compatibility. As such, they tend to have varying results when replacing the original ROM files. Additionally, general compatibility with other ROMs is poor (particularly Rareware games), with most simply crashing when the ROM is loaded, and others usually having audiovisual issues or random glitches.

The ROM will be byteswapped via UCON64 to .z64 format first, to avoid any problems that may be encountered otherwise, and is moved to the location of the emulator ROM within the WAD (usually simply named "rom"), overwriting it.

Only ROMs with an internal saving method (EEPROM (4K or 16K) / SRAM / FlashRAM) will be able to save data on VC, and games which need a Controller Pak for this function will not save at all (see here for a complete list).

If you are using this injection method, you can additionally set some options used by the emulator:

• Fix brightness: Removes any function which enables a dark/epilepsy filter.
• Extended RAM (8MB): Enables Expansion Pak emulation where it is supported.
• Allocate 32MB for ROM: Will not work for all bases, and throws an error if the byte pattern to set it is not found.

If your injected ROM encounters a region-lock error, try again using a different region revision for the ROM.

ROMC

The following rereleases use a special form of ROM compression, known as "ROMC":

• Mario Golf
• Bomberman Hero
• The Legend of Zelda: Majora's Mask
• Mario Party 2
• Ogre Battle 64: Person of Lordly Caliber

For these titles, a third-party ROMC compressor program is used to compress the original ROM. The emulator ROM, within the WAD, is stored as "romc" (not "rom") within the contents of the base WAD.
