We are moving all Atari Lynx related content over to Atari Lynx Vault and all our shop content over to K-Retro Gaming. Please update your bookmarks!
As a result of this change, the following will no longer be available: Online Lynx Emulator, Collection Tracker, Game Ratings, News. If you are interested in contributing content to Atari Lynx Vault, we are seeking editors and maintainers.
Why is this happening? First - the Atari Gamer branding is changing to K-Retro Gaming to allow us to expand to providing games, replacement parts, and mod services to other game consoles. And second - The content management system running Atari Gamer is out of date and Google AppEngine (where the website runs) will no longer allow it to run after the 30th January 2024, so in order to preserve all content we switched to a new and modern content management system and chose a website domain that better suits the subject matter. Since we are operating this website in our spare time, on top of full time family and job committments, some features had to be dropped.
This is a ROM conversion utility that can take an Atari Lynx LNX ROM file
and convert it into a headerless LYX ROM file with padding up to the next ROM byte size. Currently only ROMs up to 512KiB are supported. ROMs that are 128KiB can be converted to 256KiB ROMs. You can test you ROM using the Online Atari Lynx Emulator
. This converter also detects BLL Object ROMs
and can convert them to LYX files.
64 Byte Header
Byte 0 - 3 | Char literal | "LYNX" EEPROM byte-bits encode details of EEPROM used
4 - 5 | 16-bit uchar | Bank 0 page size bit 1 2 3 4 5 6 7 8
6 - 7 | 16-bit uchar | Bank 1 page size | | | | | |
8 - 9 | 16-bit uchar | Version number +---+---+ +---+---+ | 16/8 BIT
10 - 41 | String + \0 | Cart name | | REAL/SD
42 - 57 | String + \0 | Manufacturer EEPROM TYPE UNUSED
58 | uchar | Rotation (1=left, 2=right)
59 | uchar | AUDIN Used (1=yes) Example: 0x40 (00000010) no-EEPROM, SD card saves
60 | uchar | EEPROM detail, see right EEPROM Type values - 0: no EEPROM, 1: 93C46
61 - 63 | uchar | Unused 2: 93C56, 3: 93C66, 4: 93C76, 5: 93C86
EEPROM size is 2^(type+9)
e.g. 2^(1+9) = 1024 bits for 93C46
Lynx is little-endian so bit order is reversed.
10 Byte Header
Byte 0 - 1 | 16-bit uchar | Magic: 0x80 0x08 (08 is BS ASCII char, also bytes in hex show up as 8008 😅)
2 - 3 | 16-bit uchar | Load address
4 - 5 | 16-bit uchar | Object size
6 - 9 | Char literal | "BS93"
