Esti is a Gameboy Advance demo featuring Esti aux Malesti (later remixed into Malpith) and a Mode 7-style heat wave effect (shown below).
Developing for the Gameboy Advance via flashcart can be painful — crash and you get a blank white screen of helpfulness.
How to Play
Download and run this Gameboy Advance ROM on a flashcart or emulator.
With any luck, the demo is currently playing in the first image on this page, however without audio, thanks to GBA.js.
If you have a keyboard, the A, B and R keys are mapped to the emulator.
