PSP homebrew developer Brunni has just announced the release of the MasterBoy application as an entry to the ongoing Neo Summer Coding Competition (2007). This app is a PSP-based emulator capable of playing games from the Game Boy, Game Boy Color, Super Game Boy, Sega Master System (SMS), and Game Gear.

MasterBoy is based on Brunni's MMSPlus SMS Emulator, which was a winning entry in last year's Neo Summer Coding Competition. MasterBoy carries several new features and functions:

* Rich interface with discrete effects, redefinable shortcuts and buttons (with autofire feature). Also it's fully skinnable.
* Manage and sort your favorites folders and files to acces them easily.
* Integrated music player supporting GYM and VGM formats.
* Several display options like Gamma and Color Vibrance, which allows you to choose how colored you want your display to be.
* Z80 under/overclocker: allow you to correct games that are often slowing down or displaying glitchy / blinking sprites.
* Some improvements over MMSPlus in the SMS/GG part:
o Speed up.
o Now 16-bit render mode is enabled by default. You can revert to 8-bit if you want, and it will run even faster.
o Compatibility issues
o Better country detection (now nearly all games should detect the country correctly and not play too fast anymore).
o The bar at the left of the screen can be automatically hidden (depending whether the game is actually using it or not)

That's the basic rundown on Brunni's Masterboy emulator. Guys keen on understanding this application's full details are advised to view the readme and pdf that are included in the file bundle. Enjoy the download, and be sure to vote for Brunni's work if you enjoyed using it.
