Gameblabla’s Oswan by gameblabla is a Wonderswan/Wonderswan color, based on OswanJ by bird_may_nike and Oswan by Alekmaul. It can play most, if not all Wonderswan games properly.

Release notes from gameblabla:

New final update to Oswan : This one fixes the crashes in Klonoa, yay ! However, zear and i found graphical glitches in One piece Swan Colloseum during the super attacks, pretty minor but i still don’t know how to fix them. And there’s still Pocket Fighter with the incorrect palette at times. But pretty much every other game works properly now.

Fruit’Y – Playing with edibles is heavily inspired by the Kaiko classic Gem’X, which has been seen on computers such as the Commodore Amiga 500, Commodore 64 and Atari ST. The game consists of two boards of fruits. The left field belongs to a cute tiger who needs to reproduce the right field 1:1 being able to proceed to the next level. Sounds easy?! Possibly it does, at least for the first few levels!

Public downloads are available for these fine systems: Playstation Portable, GP2x Wiz, Dreamcast, Wii, GameCube, GCW Zero! Along with other systems not covered by PDRoms such as Amiga OS4, MorphOS, Linux, Windows, NetBSD, TI Nspire CX, …

Gameblabla’s Oswan by gameblabla is a Wonderswan/Wonderswan color, based on OswanJ by bird_may_nike and Oswan by Alekmaul. It can play most, if not all Wonderswan games properly.

It used to be based on Alekmaul’s Oswan port but the numerous issues it introduced (including incompatibility with some games) pushed me to convert everything over OswanJ SVN. This fork is also even more accurate than upstream: Games are now playing at the proper speed.

The CPU core comes from NomadSwan (GPLv2 or later). Somes changes were made in order to remove useless code.

Solarus is a free and open-source Action-RPG game engine, licensed under GPL, and written in C++. It runs quests in Lua, and can work on a great number of platforms. Solarus also features a game editor called Solarus Quest Editor, written in C++ with Qt to help you creating your game.

The previous port by Shin-nil is now two years old and suffers from a number of bugs, notably music stuttering when changing areas. The new version still occasionally stutters but has smoother sound, many bug fixes and engine enhancements.

Barbie Seahorse Adventures is a fun little platformer made by The Olde Battleaxe for the PyWeek 4 contest. Rewritten for GCW Zero by Nebuleon.

You’re a seahorse, and you have to go to the Moon! There are enemies in your way, which you must defeat, and landscapes that will end up confusing you…

You shoot bubbles from your… face… and those bubbles destroy enemies and turn them into bubbles, which you can ride to raise yourself to new heights. Three bubbles from your face are enough to defeat most enemies, or one if you have hair, but there is one thing that your bubbles cannot defeat alone…
