Version 1.20
New features
- Added xxHash32 integrity checksum: every compressed G3Z file now stores a 32-bit hash of the original uncompressed data, verified automatically on decompression
- Checksum is algorithm-agnostic: works identically for zlib and LZ4 compressed files
- Old G3Z files (versions 1.10--1.13) without a checksum are still decompressed normally (flag
0x00 skips verification)
- Named constants for algorithm byte codes (
ALGO_BYTE_ZLIB_MAX/FAST, ALGO_BYTE_LZ4_MAX/FAST) replacing bare character literals in the file format layer
- Checksum value in the file information popup is now displayed in hexadecimal (e.g.
0xA3F2C1B0) consistent with how hash values are conventionally represented
Bug fixes
- Fixed use-after-free: partial
.g3z output is now correctly deleted before the path buffer is freed when compression is aborted
- Fixed
jpopup_add_empty_line(): empty separator lines were allocated but never inserted into the list and never displayed
- Fixed popup widget used before NULL guard:
jpopup_set_size() and jpopup_set_font() were called before the NULL check in init_app()
- Fixed missing
FileData argument in the non-FXCG100 build path of SquishIt_GetFileInformation() (crash / undefined behaviour on simulator)
- Fixed buffer overflow in
getfileinformation(): name_len read from file was not clamped before fread() into the 256-byte originalfilename field
- Fixed
delete_file() returning the raw remove() value (-1 on failure) instead of a defined SQUISHIT_* error code
- Fixed unchecked
fwrite() in LZ4 compression and decompression loops: write failures now propagate as SQUISHIT_WRITE_ERROR
- Fixed unchecked
fwrite() when writing the filename into the G3Z header
- Fixed LZ4 chunk size stored/read as platform-dependent
int; now explicitly uint32_t (no format change on SH4 where int is 32 bits, but correct by specification)
- Fixed
strcpy() without bounds check on FileData->filename; replaced with strncpy()
Code quality
- Refactored
event_handling() (~215 lines) into three focused static helpers: handle_compress(), handle_decompress(), handle_info_popup()
- Removed stale TODO comment from
read_checksum() (error handling was already complete)
- Removed dead commented-out
decompress_file_zlib() function
- Added
static to clamp() in jprogressbar.c to avoid link-scope name pollution
- Removed dead
l = NULL assignment after free(l) in jpopup_poly_destroy()
- Corrected misleading copy-paste header comment in
jpopup.h (was describing a progress bar)
- Replaced unexplained commented-out
jwidget_emit() calls with an explanatory comment
- Updated G3Z file format to version 1.20
Version 1.21
New features in 1.21
- Multi-language support (English / French): all user-facing strings are now fully translated; the active language is selectable from the Settings menu
- Persistent user settings: language, CPU overclock level and default compression algorithm are saved automatically to
SquishIt.ini on the calculator storage and restored on the next launch
- INI configuration file (
SquishIt.ini): plain-text format with [Key] value entries and # comment lines; human-readable and hand-editable directly on a PC; a default file with full comments is provided and auto-created on first launch if absent
- CPU overclock is now accessible from the Settings menu (SHIFT+MENU), allowing the user to select speeds F1 (default) through F5 without leaving the application
- Default compression algorithm is now remembered across sessions and pre-selected on startup
Code quality in 1.21
- Introduced
src/lang/ subsystem: lang.h (string ID enum + API), lang_en.h, lang_fr.h (translation tables), lang.c (runtime dispatch); adding a new language requires only a new lang_XX.h file
- Introduced
src/core/ini_file.h / ini_file.c: self-contained INI parser and writer; all filesystem calls are wrapped in gint_world_switch for safe OS-world access
- Widget strings (
jpopup title, jjackintheboxmenu hint bar, jfileselect empty-folder and save-as labels) are now configurable at runtime via dedicated setters, enabling live language switching without rebuilding the widget tree
