Description:
Amico8 is a PICO-8 fantasy console emulator for Amiga computers with a
68020 or better processor. It loads and runs PICO-8 cartridges in
both text (.p8) and image (.p8.png) format directly from the Amiga
file system.
Features:
- Runs many PICO-8 cartridges (.p8 and .p8.png) without modification
- Full 128x128 pixel display, 2x scaled to 256x256 via Amiga copper tricks
- 16-colour PICO-8 palette mapped to Amiga 12-bit hardware palette
- Joystick (port 2) and keyboard input
- Mouse support (port 1) for carts that use mouse API
- Paula audio: triangle, sawtooth, square, pulse, organ, noise waveforms
- AOT (Ahead-of-Time) native code compiler for Lua numeric functions
- BBS
Two executables are provided:
Amico8 - 68020/030 version, no FPU required.
Runs on any Amiga with a 68020 or better.
Amico8_040 - 68040/060 version, requires FPU.
Takes advantage of 040/060 instruction scheduling.
Recommended processor: 68060.
Usage:
Amico8 - start with GUI! (recommended)
or
Amico8 ?
Limitations:
- Some newer PICO-8 API calls may not be implemented
- Sound effects and music play, but advanced effects (vibrato, slide,
arpeggio) are not yet implemented

Tested games:
LIST IN PROGRESS BUT CHECK THIS GAMES FIRST!:
Celeste, Celeste 2, Just One Boss, Combopool, Low Knight
Undune
For now 2/3 of games will start, 1/3 of games will run ok :)

Code used:
Lua 5.2 - scripting engine base

Authors: R. Ierusalimschy, L. H. de Figueiredo, W. Celes
License: MIT (http://www.lua.org/license.html)
The Lua VM and standard libraries form the core of the interpreter.
z8lua - PICO-8-compatible Lua fork (from the Zepto-8 project)

Source: https://github.com/samhocevar/zepto8
z8lua extends Lua 5.2 with PICO-8-specific syntax (short-if, compound
assignment operators, integer division, fix32 number type, PICO-8 math
functions). The file z8lua/lpico8lib.c is taken directly from Zepto-8.
p8_compress - PICO-8 cartridge decompression
Copyright (C) 2014-2022 Lexaloffle Games LLP
License: MIT
Decompresses PICO-8 Lua source code from both old ":c:" format and
modern "pxa" compressed format.
stb_image - PNG image loader
Author: Sean Barrett

Used for loading .p8.png cartridge images.
FAKE-08 - reference PICO-8 implementation
Author: Jonathan (jtothebell)
License: MIT
Source: https://github.com/jtothebell/fake-08
Source code was invaluable for verifying PICO-8 behavior ? API
semantics, iterator edge cases, metatable setup, _update_buttons
contract, etc. ? against a known-working C++ reference. Not used
in the Amico8 binary, only consulted during development.
