- Make .nfo pseudo-sprite format more versatile:
  * no lengths, instead line-continuation with backslash-cr or backslash-lf
  * allow hex, dec, oct postfixes like assembly (40, 24d...), default hex
  * allow byte, word, dword and string values (W:4, D:60d, "Hello there")
- Finish linter:

  - Eat all comments, not just messages (?)
- Config file (!)
- Auto-correction:
  - Action 7/9 num-sprites if it jumps to or past EOF.
- Multiple backups
- gcc-style output (file:line)
