v0.9
542e42e

First public release of loadimg, a modern replacement for the Midway LOAD2/LOADW arcade asset tool.

What's New in v0.9

  • Fixed BBMUG 16-bit checksum collisions causing false deduplication matches by adding a sum2 byte-sum dual-hash mechanism.
  • Fixed BB6 CHEER bpp selection by properly scanning the stride-width pixel buffer (matching LOADW's handling of padding artifacts).
  • Fixed BB7 cascade failures by gating the PTTBL seq/scr offset skip to < v0x654 and enforcing a minimum SIZX threshold of 10.
  • Added -v and --version CLI flags.
  • Cleaned up debug print leftovers.

Known Limitations

  • BB5 CMP=1 Encoder Cascade: The LM/TM multiplier selection algorithm diverges from LOADW for some compressed images.
  • BB6 PLYRDSQ2: PT fields fail to compute correctly due to PTTBL 40-byte stride aliasing reading pixel data.
  • BB7 OUTDOOR: A 20-byte SAG shift due to LOADW's buggy false-deduplication of LEAF7/LEAF8. This tool produces correct output, meaning it won't 100% byte-match the original buggy reference files.
