## cc65 to omf
Convert [cc65](https://cc65.github.io) object files and libraries to OMF object files and libraries.
Why? The original idea was to use ORCA/M or MPW Asm IIgs with
[ip65](https://github.com/cc65/ip65), so I don't have to learn ca65. Of course, ca65 is a fine assembler and in some ways better...
## Conversion
* Imports -> N/A
* Exports -> OMF `GLOBAL` or `GEQU` entries
* ZEROPAGE segment -> OMF Stack segment
* other segments -> OMF Code segments
## Warning
cc65 object files allow you to import symbol then export it under a different name (and possibly as part of a larger expression). ORCA/Linker 2.1.0 (or newer) is recommended as older versions won't properly evaluate them. Apple's linker (for APW or MPW) handles them better but there may still be issues.
