An unofficial PS Vita port of **World of Illusion Starring Mickey Mouse and Donald Duck** (Sega Mega Drive / Genesis) by Loki D.S.

The game runs on a built-in Mega Drive emulation core with widescreen patches: the view is genuinely widened — enemies, items and the HUD are all included — rather than stretched. The game is not included; you need your own ROM dump.

## What's new

First public release.

## Features

* **Widescreen:** Off, 16:10, 16:9 and 2:1. The width can be changed in the menu, including mid-level.
* **HUD anchoring:** the status bar and counters are pinned to the screen edges.
* **Cheats:** invincibility, infinite hearts, infinite tries, maximum hearts.
* **Saves:** one save-state slot.
* **Settings:** stored in `settings.ini` and kept across restarts.
* **LiveArea art:** custom icon, background and a startup screen with transparency.
* **Controls:** D-pad/stick, X, □, ○, Start and Select, mapped for the Vita.

## Installation

1. Install `WorldOfIllusion.vpk` with VitaShell (HENkaku/ensō required).
2. Put the ROM in:

`ux0:data/MickeyAndDonald/roms/`

It is also searched for in `ux0:data/MickeyAndDonald/`, `app0:roms/` and `app0:`. The ROM can be kept in a `.zip`.
3. Launch “World of Illusion” from the LiveArea.

On first launch, `ux0:data/MickeyAndDonald/` is created (`settings.ini`, `log.txt`; saves go to `saves/woi.state`).

**You need your own game dump.** The port targets the USA version:

`World of Illusion Starring Mickey Mouse and Donald Duck (U) [!].bin`
