Back in 2006 when learning C coding, I wrote a demo that replicates the dungeon crawling experience from Silmarils' 1992 game Ishar: Legend of the Fortress.

However around 2008 I lost the source code (didn't know about version control back then, and my computer was stolen), but could retrieve the ROM that had been published on PDRoms.

This demo uses GBFS as a virtual file system. This repo contains the demo ROM as well as the code-only ROM, and all the assets.
