+# numworks-nofrendo
+
+A NES emulator for the NumWorks calculator
+
+## Easy Installation
+
+See here : https://zardam.github.io/webnofrendo/
+
+## How to build
+
+```bash
+git clone https://github.com/numworks/epsilon.git
+cd epsilon
+git clone https://github.com/zardam/numworks-nofrendo.git apps/nes
+make EPSILON_APPS='calculation graph code statistics probability solver sequence regression settings nes' epsilon.bin
+cat your_nes_rom.nes >> epsilon.bin
+make EPSILON_APPS='calculation graph code statistics probability solver sequence regression settings nes' epsilon_flash
+```
