Welcome to Frogger 2: Swampy's Revenge for Ti-Nspire CX II.

This game is a port of Frogger 2: Swampy's Revenge(2000) from the PlayStation to the TI-Nspire CX II.
While it will technically run on a TI-Nspire CX, it is just too slow.

PSX Source Code: https://github.com/HighwayFrogs/frogger2-psx/
Including the source code for this on ticalc.org did not work because it was larger than ticalc.org's file size limit.

**How to install:**
1) Obtain FROGGER.DAT from your PSX game disc (insert it to your CD drive) to your computer.
Alternatively, if you do not have a disc drive handy, but have a legally made backup (in .iso or .bin/.cue format), you may use software such as PowerISO, ISOBuster, or any other tool capable of opening PSX disc backups and extracting files.
One open source option is dumpsxiso, available as part of mkpsxiso: https://github.com/Lameguy64/mkpsxiso/releases
Just drag your .bin/.cue/.iso file onto dumpsxiso.exe and it will give you the files, including `FROGGER.DAT`.

Both the NTSC and PAL versions of Frogger 2 should work. However, the PC/Dreamcast versions of Frogger 2 will not.

2) OPTIONAL: FROGGER.DAT is a whopping 32MB, but we can slim it down to 12MB to save space.
Drag `FROGGER.DAT` onto `frogger2-dat-cleaner.exe`, and it will give you a new file `FROGGER.DAT.tns`.

Alternatively, if you're on Linux, Mac OS, or would just rather not run some random exe file, I've included `frogger2-dat-cleaner.html`. Open this file in your web browser, and it will let you cleanup your FROGGER.DAT file all the same.

3) If you skipped step 2, then you must rename `frogger.dat` to `frogger.dat.tns`.
If you did not skip step 2, then you already have a file `frogger.dat.tns`.

4) Copy both `frogger2.tns` and `frogger.dat.tns` to your calculator, in the same folder.
You are now ready to play.
