Plants vs. Zombie

Plants vs. Zombies for AmigaOS 4

This is an AmigaOS 4 port of Plants vs. Zombies, based on the PvZ-Portable
project by wszqkzqk:

https://github.com/wszqkzqk/PvZ-Portable/releases/tag/0.1.26

=== Requirements

You must provide the original game data files.

The AmigaOS 4 version was built and tested using:

Plants vs. Zombies GOTY Edition

- Version: 1.2.0.1096
- Build: 11226
- Original Release Date: May 5, 2009
- Build Date: December 15, 2010

=== Installation

Copy the properties directory and main.pak from your original game installation
into the game's root directory. The final directory layout should look like
this:


Plants/
properties/
main.pak
pvz
pvz.info
readme.txt
readme.txt.info


Once everything is in place, simply run the game.

If you start it from a Shell, debug information will be printed to the console.
If you launch it by double-clicking its icon, all console output will be
suppressed.

=== AmigaOS 4 Specific Changes

The AmigaOS 4 version is built statically, so no SObjs-hell.

It uses SDL2 together with ogles2.library, and includes a number of OS4-specific
fixes and improvements:

- General compatibility fixes, including path handling, stack cookie, file
loading/saving, proper cleanup, and co.
- Fixed PNG alpha channel handling in png_set_swap_alpha() and added OGLES2
workarounds for the A8R8G8B8/RGB565 pixel formats.
- Fixed several rendering issues present in the original code
- Fixed blinking cursor.
- Reworked the resource loading process to keep the visuals synchronized while
game data is being loaded.
- Updated and optimized `libopenmpt.a` for faster unpacking and seeking of large
MO3 music files.
- Added improvements to ensure music starts and plays correctly while the game
is loading.
- Optimized rendering by introducing batching to reduce the number of draw
calls.

Have fun!
