wonderful-i8086

Experimental C toolchain for the WonderSwan. Early development.

Known limitations

• Read-only data (const arrays, etc.) will only end up in ROM if declared as __far.
  • To be more precise, by default, pointers are near pointers. In wonderful-i8086, this means they can only point to the console RAM. To point to SRAM or the console ROM, far pointers must be utilized.
• The WonderWitch target has compilation issues on non-trivial code, due to the necessary logic to handle DS ≠ SS. This is unlikely to be resolved shortly.
  • tkchia: "Yes, unfortunately support for %ss ≠ .data code is still extremely hacky and involves some not-quite-reliable deep black magic. (GCC was never quite designed in the first place to work with non-flat address spaces. Plus, the libgcc library was definitely not written with a %ss ≠ .data environment in mind.)" (source)
