Getting sprites out old dos game can be hard. You will not find standard images formats like png, jpg or dds. It can be stored in extremely convoluted way. One game I ripped the sprites from (Panzer General) used a strange pen method where it stored all images as move pen left, right, draw color X... like G-Code for CNC machine.
I would recommend just taking a bunch of screen shots and cutting out the sprites in image editor. You can also just use whole map as a single image like: [https://faqs.neoseeker.com/Games/PC/zeliard_milagro.png](https://faqs.neoseeker.com/Games/PC/zeliard_milagro.png) No need to mess with spires/level data.
