The Graph Math+, released in late 2024, is very similar to the G90+E but suffers from a severe reduction in available user flash memory: only 4.5 MB, compared to 16 MB previously.
For regular users, this limitation is acceptable. For power users and developers who maintain and test multiple add-ins, this drastically reduced storage becomes a daily obstruction.
Squish It !! was created to address this limitation by providing on-calculator compression and decompression for add-ins, allowing users to effectively expand their usable storage.
The tool introduces a custom compressed format G3Z) and integrates several efficient compression algorithms.
Run only on fxCG-100 or Graph Math+.
Not compatible with Prizm machines and fxCG-50 / Graph 90+E.
Minimum OS version: 2.00 Prerequisite: Jailbreak via the latest MPM (Planète Casio Forge)
How Squish It !! Works
The program lists:
- G3A files --- uncompressed add-ins
- G3Z files --- compressed add-ins using the Squish It !!
proprietary format
The interface allows:
- Compressing a G3A → G3Z
- Decompressing a G3Z → G3A
The operation starts by pressing EXE or OK.
Squish It !! automatically detects:
- File type
- Compression algorithm
- Required buffer size
Compression and decompression operation can be stopped by pressing the BACK key.
Available Compression Algorithms
- ZlibMax --- zlib, maximum compression ratio
- ZlibFst --- zlib, optimized for speed
- LZ4Max --- LZ4 HC, level 9
- LZ4Fst --- LZ4 HC, level 3 (fast)
Reliability
To ensure reliability, 31 different add-ins were processed through all
methods:
- Compressed
- Decompressed
- Executed after decompression All tests passed successfully.
A safety mechanism prevents compressing Squish It !! itself.
Disclaimer
This software is a Work in Progress and is provided "as is", without warranty of any kind.
Although extensive testing has been performed, unexpected behavior may occur.
Please:
- Avoid using it on sensitive or irreplaceable data
- Ensure regular backups of your calculator storage
- Send bugs reports when you find some (with possibly the way to reproduce it as accurately as possible)
