Sega Channel BIOS (US)
This game has a prototype article
|This game is defunct.|
Do note the game no longer works at all without modifications. This is most likely due to the game's servers being shut down. As a result, further official developments with the game are unlikely to happen.
The Sega Channel was Sega's early attempt at a broadband media delivery service. It provided a continuously looping one-way stream of data on a hidden channel which the Sega Channel tuner would "catch" and then download to its internal memory for usage. New streams were provided monthly to the user at a cost of roughly $15 per month.
Although it caught on almost exclusively in the United States, it was instrumental in later broadband Internet deployment by encouraging participating cable operators to upgrade and maintain their systems for cleaner digital delivery.
- Note: ROM addresses refer to the Scientific Atlanta version of the ROM, but the strings appear to exist in the General Instruments version as well.
Present at 0x12B99 is a compiler error that somehow made it into the ROM.
Math library must precede standard C library on linker command line to access printf() that supports floating point
Starting at offset 0xCDDE is a large chunk of credits, followed by an odd comment about fast-food catering, a fan club address (with the developers replacing vital information with X's), and a copyright notice.

Likely present to fill space before data was downloaded from the cable operator, or maybe just for testing. Curiously, ticker five line one includes an extra "WO" in its text.

Generic error messages, possibly displayed in operation if a serious error occurred, or simply used during debugging.

Remote Diagnostic Tools
Possibly meant for cable operators to provide remote support using equipment at the headend, pieces of a remote diagnostic tool are located starting at offset 0x34DF. What could be done remotely, if anything, is unclear, although some of the text indicates the existence of a downlink test that would fill RAM with dummy data, and a debug display that would list the contents of the 68000 registers and stack pointer.

This diagnostic tool appears to be for developers, as it gives out the internal registers within the Sega Channel cartridge and also returns the value of the game downloaded. It begins at 0xA32C in the ROM.

There's also a small DRAM writing test at 0xAD24.
