MISA Tilemap Renderer

A tilemap rendering engine written in assembly language for the MISA architecture (Mnemonimov Assembly).

This project demonstrates a simple tile-based rendering system implemented entirely in assembly. The renderer reads map data stored as raw byte arrays and converts tile values into drawable objects.

Features

• Written entirely in MISA assembly
• Tilemap-based rendering system
• Supports custom map data stored in memory
• Configurable map dimensions
• Simple binary tile format (0 = empty, 1 = solid tile)

How to run

Create a new directory inside Mnemonimov's user_projects folder and clone this repository into it.

Map Format

Maps are stored as arrays of u8 values:

1,1,1,1
1,0,0,1
1,0,1,1
1,1,1,1

Each value represents a tile:

Value	Meaning
0	Empty space
1	Rendered tile

Configuration

Map size and tile size can be configured:

def WIDTH 32
def HEIGHT 24
def TILESIZE 10

The renderer calculates the total amount of tiles automatically:

def TOTAL_TILES WIDTH*HEIGHT

Rendering Process

The renderer:

1. Initializes a pointer to the map data.
2. Iterates through every tile.
3. Checks the tile value.
4. Converts the tile index into an X/Y position.
5. Draws the tile using the MISA graphics system call.

Example:

mod s2, s0, WIDTH   # X coordinate
div s2, s0, WIDTH   # Y coordinate

Example Maps

The project includes multiple test maps:

• sq - Simple square pattern
• sq2 - Circle-like pattern
• sq3 - Filled shape test
• lettera / letterb - Character rendering tests
• fullsizetesting - Full 32x24 map test
• maze - Maze rendering test
