GBA Jam 2026 logo done in chipped and dripping graffiti paint style in front of an exploding Game Boy Advance cartridge, with a flurry of blue and purple paint specs behind it on a solid black background.
A recording of a tech demo for GBA titled Project PAG (Pocket Adventure Game) by Gronis. The player controls a blonde character wearing a red cloak moving on a green field through blocks, barrels and other objects that have get pushed to the opposite side of the player's movement. There are butterflies flying around in random directions, every now and then one of the butterflies speaks through semi-transparent dialog boxes with white text font appearing above it and moving in the same direction as the speaking butterfly. The player character can also speak in dialog boxes when interacting with objects in the game.
A video of gameplay clips from two Game Boy Advance releases by screenshake farm. The first clip is of Ferdinand Fox tries Ecoterrorism showcasing the microgame stage selection menu, which shows the protagonist, Ferdinand Fox, sleeping in his house under train tracks. The stages can be selected from cards below. Out of four cards, the Art Protest stage is chosen, following that is the first Art Protest microgame where the player has to draw a protest sign by moving the paintbrush cursor around the screen. The second clip is from Drawing a Leviathan, showing a stick figure diving down a monochrome ocean while being surrounded by fish. The game then switches into drawing mode, where one of the swimming fishes is recreated by the player in two-color pixel art form on a 12 by 12 grid on the right side of the screen, which allows it to get "captured" in exchange for a small amount of money.
A playthrough of Timebeat for Game Boy, showing the title screen with the game name, credits, a picture of a stopwatch, and the menu with three song options, "Past", "Future" and "Present". Following footage are snippets of the levels, where the inputs (left and right arrows, A and B buttons) drop down in front of scrolling backgrounds and must be pressed in time with the beat when they reach the bottom of the screen. In order of appearance: the Past song has a backdrop with dinosaurs, volcanoes and palm trees, the Present has skyscrapers reflecting in a body of water, flying aircrafts and mountains, the Future - outer space with stars, spaceships, ruins and a giant Moon.
A recording of a playthrough of some of the microgames that comprise the Green River College Software Development Cohort 23 microgame collection for the Game Boy Advance, all of which have a common cosmic/space exploration theme. The order of the games is as follows: steering a spaceship away from a magnetic void; shooting a number of rocks in an Asteroids clone; moving Moon between Sun and Earth to create solar eclipse; collecting stars as an astronaut cat; dodging falling rocks as a rocket; dodging flaming asteroids as a yellow alien. Each transition to a new microgame shows an animation of a cute blue UFO ship with eyes and a yellow bow on the side, as well as the amount of lives left, represented by tiny astronauts walking in place on top right.
