'Another Guest' is a name from the past that cropped up again recently, along with the news that new emulators, updates of existing ones and new games altogether have been released for Symbian recently. See below for some highlights - if you like your retro gaming then maybe these are all worth a look?

From the Another Guest site - follow the title links for full post details and the download instructions:

OhBoy 1.00(0)

A gameboy emulator using the gnuboy emulation core.
Oh Boy is an SDL port of gnuboy and offers:

• frame skipping
• GUI menu for loading roms
• GUI menu for some settings and saving them to gnuboy .rc files
• FPS indicator (from SDL gnuboy port)

Then there's this update:

ScummVM 1.70(0)

ScummVM is a program which allows you to run certain classic graphical point-and-click adventure games, provided you already have their data files. The clever part about this: ScummVM just replaces the executables shipped with the games, allowing you to play them on systems for which they were never designed!

And then some games which were new to me:

Tile World 1.30(0)

Tile World is a reimplementation of the game "Chip's Challenge". The player controls Chip, navigating him through his challenges. The object of each level of the game is to find and reach the exit tile, which takes you to the next level. The levels contain many different kinds of obstacles, creatures both hostile and indifferent, tools, protective gear -- and, of course, chips.

...and...

Digger

Originally for the Nintendo, Digger is a game where you try to collect the diamonds and bags of gold while avoiding getting caught by your enemies. 

 

...and...

Xump 1.10(0)

Xump game consists of a 20 x 12 playfield, filled with different types of blocks.
The player must make the blue blocks disappear from the playfield by stepping on them. There are five main types of blocks, each of which behave differently.

...and, older, but still interesting...

Interlogic 1.00(0)

The game InterLOGIC is based on the old Amiga logic game "Balls". The object of the game is to move balls of different colors through a maze, connecting them with other balls of the same color. Two or more connected balls of the same color will disappear. The aim of the game is to clean the whole maze in this way. The balls are connected if they are right next to each other horizontally or vertically, but not diagonally. The current release contains 30 mind-breaking levels for you to solve.

Great stuff, and definitely showing that Symbian development hasn't stopped completely.
