I am back with new experiment - real emulator of my second favorite retro platform for my first favorite retro platform :)

You can show virtual keypad by pressing B on P2 controller, then use P2 arrows and A button to press keys.

Emulator is preloaded with those games:

  • Rush Hour by Hap
  • Astro Dodge (hi-res)
  • Worm V4 (hi-res)
  • Space Invaders by David Winter
  • Tetris.
  • TRIP8 hi-res demo

Rush Hour controls:

  • ARROWS - movement
  • Z - select
    Only code I found: 4A10 :D

Worm V4 controls:

  • ARROWS - movement
  • Z - reset

Astro Doge controls:

  • ARROWS - movement
  • Z - start

Space Invaders controls:

  • LEFT/RIGHT - movement
  • Z - shoot

Tetris controls:

  • LEFT/RIGHT - move
  • UP - rotate
  • DOWN - drop

Some technical details:

  • emulator runs at 1500 cycles per second (successfully tested at 3000 cycles per second)
  • timers are set correctly to 60Hz
  • game rom is stored as map data (currently 1 game per pico rom)
  • screen is stored directly in spritesheet
  • pico keys are custom-mapped to chip8 keys
  • cpu specification: 35 opcodes, 16 8-bit registers, 64x32 b/w screen, 4k rom/ram

Changelog:

1.5

  • fixed sprite drawing
  • added emulator restart button (for games that end in loop or halt)
    1.4
  • fixed clear screen routine
  • added support for hi-res mode
    1.3
  • fixed key handling
  • added full chip8 keypad (p2 controller)
    1.2
  • fixed font sprite location to reflect emulator's default font position in memory
    1.1
  • simple debugger mode easily switchable by variables
  • wait for key-press fixed
  • beep fixed
  • shl and shr instructions fixed

If anyone want to take a look and play, please use RUSH-HOUR rom. Many bugs I found are fixed there ;)

Simple ray-caster experiment.

It's not perfect, but it's kinda working and I hope it can serve as starting point for some awesome 3D games - especially I am thinking about some cool dungeon/rpg, that would be awesome!

Controls: arrows to move

Update 1.1:

  • added fish-eye effect reduction
  • added dynamic quality settings (when camera moves, quality is lowered)
  • draw distance, step & quality setting can be adjusted in code

Two mighty Viking warriors are splitting loot after great battle but only the clever one can have more of it!

Simple game for 1-2 players. Loot is falling onto table, you can grab it by pressing your action button, but be sure not to wait too long, otherwise your opponent will sure take it first! Whoever reaches limit first wins the game.

Controls:
Red-bearded warrior: Z
Blue-bearded warrior: DOWN ARROW
Limit selection: LEFT & RIGHT ARROWS

This game was heavily inspired by Mind Fuck by Anna Anthropy (auntiepixelante.com)
