missing 512 byte table generator, which doesn't look trivial to do (especially in terms of code size). Not tested, but looks as decent speed up.
Z80 asm implementation of C unpacker, code-size focused (not performance). **ONLY BITSTREAM** variant is currently supported, make sure to use "-b" in packer. The project is expected to further evolve, including possible changes to binary format, this is initial version of Z80 unpacker to explore if/how it works and how it can be improved further. (copy full packer+depacker source to your project if you plan to use it, as future revisions may be incompatible with files you will produce with current version) Asm syntax is z00m's sjasmplus: https://github.com/z00m128/sjasmplus TODO: - build base corpus of test data to benchmark future changes in algorithm/format - review first implementation to identify weak spots where the implementation can be shorter+faster with acceptable small changes to the format - review non-bitstream variant, if it's feasible to try to implement it with Z80 - (@ped7g) Z80N version of unpacker for ZX Next devs - (@exoticorn) add Z80 specific packer (to avoid confusion with original MicroW8 variant), and land it all to master branch, maybe in "z80" directory or something? (and overall decide how to organise+merge this upstream into main repo)
