Games and tools
that run on a calculator.
I build homebrew for Casio fx-CG50, TI-Nspire and friends — arcade ports, puzzle games and the low-level libraries that make them fast on hardware with no floating-point unit.
Who I am
I'm Sylvain (SlyVTT) — a C/C++ developer who spends his spare time squeezing real games and tools into graphing calculators.
Most of my projects target the Casio fx-CG50 / Graph 90+E with Lephé's gint and Azur, and the TI-Nspire. Along the way I write the libraries the games need — fixed-point maths, a cross-platform widget toolkit, keyboard / RAM / overclock helpers — because a 118 MHz machine with no FPU doesn't forgive wasted cycles.
Ports of classics (Another World, Flashback, Prince of Persia), original games (Droppy, Lumines, OutRun 2), and the plumbing underneath: that's the mix you'll find here.
