Gamer Driver

The Transformation Belt Gamer Driver (変身ベルトゲーマドライバー) is a transformation belt for the Ex-Aid Riders.

Design
The Gamer Driver consists of the following parts:
 * GD Hyper Module (ＧＤハイパーモジュール), a V-shaped silver data materializer installed on the top of the driver. It can materialize suits and weapons in the game area based on the data recorded on the Rider Gashat. The inside is black-boxed. Only developers can understand the basis of the system.
 * Actuation Lever (アクチュエーションレバー), the pink lever used when level up is executed. By pulling the lever, it will activate the reinforcement program written on the Rider Gashat installed. The ability of Rider will increase and new equipment will be materialized. Also, Rider can cancel the transformation by removing Gashat after closing the level.
 * High Flash Indicator (ハイフラッシュインジケータ), a light emitting panel installed on the centre of the driver. The graphic of the installed Rider Gashat will be displayed. Also, it has the function to act as command menu and can project image into air when attacking.
 * Main Gashat Slot (メインガシャットスロット), the slot for Rider Gashat used in transformation or level up process. It can instantaneously read the data of the inserted Gashat, and automatically execute transformation programs. Also, the Gashat used for transformation is inserted in the slot closer to the centre of the driver while insert in the other driver for level up.
 * GD Updater (ＧＤアップデーター), a black data communication device installed next to the Main Gashat Slot on the driver. In order to improve the performance of the driver, it has a function to automatically transfer battle data to the data server of the development company. Also, correction patches that solve system problems will be automatically downloaded and installed.
 * Outer Guard Case (アウターガードケース), the exterior parts to protect the internal function of the gamer driver. Lightweight and high strength materials that are easy to mold and use are used, and the surface layer is coated with a coating agent which enhances water resistance, heat resistance and impact resistance. Also, a cooler unit is installed to prevent thermal runaway.
 * Fitting Bind (フィッティングバインド), the belt part of the driver. The length of the belt is automatically adjusted according to the body shape of the Rider. Also, using the bioenergetic energy absorbed from the Rider, energy is generated to operate each system of the driver.
 * Vital Connector (バイタルコネクター), a black device connecting two ends of the belt on the back, also monitors the health condition of the Rider. It can determine whether the wearer is a conforming person, and activates various functions of the driver only when the wearer is recognized as a conforming person. It also has the function of measuring the physical data of the wearer and automatically adjusting the size of the suit.

Compatibility
Before someone can properly use the Gamer Driver, they must become a candidate by undergoing a compatibility surgery, which introduces a small sample of the Bugster Virus to their body to induce antibody production. This presumably allows them to handle the side effects of usage, which would otherwise be dangerous. When a Rider gets a game over, the body of the Gamer Driver user will disintegrate into data. It is very safe to be used by the human users who have a natural Bugster antibody or possibly by the Bugster themselves. This compability could be rendered invalid, although so far, Ex-Aid Maximum Gamer Level 99 is the only one who can do so.

If a normal human tries to use a Gashat while wearing the Driver, the Game Start screen will glitch and stop working, and if they have been infected with a latent Bugster virus, the infection will immediately reactivate. If a normal human tries to use a Proto Gashat while wearing the Driver, it will cause.

Transformation

 * By inserting an active Rider Gashat into the right Gashat Slot, the user is able to transform into a Level 1 Kamen Rider.
 * By opening the Actuation Lever to reveal the High Flash Indicator projecting a transformation screen into the air in front of the Rider, a Level 1 Rider is able to level up to Level 2 by passing though the screen.
 * By quickly opening the Actuation Lever right after inserting the Rider Gashat into his Game Driver, the user will skip the Level 1 and directly transform into a Level 2 Kamen Rider.
 * By closing the Actuation Lever, a Level 2 Rider can revert to Level 1.
 * By closing the Actuation Lever after activating another Rider Gashat, a Level 2 Rider will not revert to Level 1, and the user will be able to insert the Gashat into the left Gashat Slot and reopen the Actuation Lever to level up to Level 3 by passing through the pair of projected transformation screens.
 * By inserting a second Gashat in the left Gashat Slot while in Level 1 and opening the Actuation Lever for the first time, the user is immediately taken to Level 3.
 * The same procedures for Level 3 are used to access Level 4 - Level 5 if the second Gashat is either Level 4's Ju Ju Burger and Night of Safari, or Level 5's Drago Knight Hunter Z.
 * If the Gashat's weight appearance is bulky which can only insert one to fit in the two Gamer Driver's empty transformation slots, the Rider will open the Actuation Lever to transform into their powerful form(s), the same procedures is used for Level 50 or Level 99 if the Gashat is the some of Gashat Gear Duals (original (Level 99) or β (Level 50) or Maximum Mighty X (Level 99). To perform Critical Finisher, the Rider must close and re-open the Actuation Lever.
 * Mighty Brothers XX in case, which started from Level X to transform into Level XX is different, the user require to close the Actuation Lever, then re-open it. However, it is unknown how the Level XX Rider is able to revert back to Level X, as re-closing and re-opening the Actuation Lever while in Level XX will immediately goes to Critical Strike.
 * If the user wants to use Critical Strike while in Level X without transforming to Level XX, the user must re-open the Actuation Lever Twice.
 * For original Gashat Gear Dual, which only have 1 form, Level 99, it has one more finisher besides Critical Combo and Smash, which is Critical Bomber, as the Rider requires to rotate the Gashat Gear Dual's roller before re-opening the Actuation Lever.
 * By closing the Actuation Lever and removing the Rider Gashat(s), a Level 2 or above Rider's transformation will be canceled. Similarly, a Level 1 Rider can also cancel their transformation by removing the Gashat. This possibly means that a Kamen Rider cannot perform a Critical finisher while in Level 1 without using an additional Gashat.
 * When a Rider's Rider Gauge is critically low, Gamer Driver's protection function will automatically eject the inserting Gashat to cancel the transformation and preserve their life. This function, however, can be prevented by the Rider themselves, or by the Deadly Jammer of Zombie Gamer.

Playable Games
The Gamer Driver has a list of playable games corresponding to the Rider Gashats. When a game's victory condition is fulfilled, typically by defeating the Bugster born from that game's data, a projection from the belt states "Game Clear!" over the corresponding image of the Gashat (the Gashat itself needs not be the one used to defeat its corresponding Bugster). The Gamer Clear count is independent from the Rider who cleared it, as when a Rider clears a Game, other Riders' previously cleared Games are also shown as Clear. The only exception was a production error in episode 3, where after Snipe cleared Bang Bang Shooting, none of the other games were labeled as cleared. The overall "Game Clear" count was also kept track of through a screen in Kuroto Dan's office at Genm Corp.

After the 10 games were cleared, however, "Game Clear!" is still announced upon the defeat of a Bugster, though without the projected list of game titles. This seems now to simply indicate that a battle has been won and no longer relates to the Gashats being used, as there is no longer a connection between the Gashat involved and the Bugster defeated (excepting Ju Ju Burger and Burgermon). As such, the specific Gashat games themselves no longer seem to be "cleared" by defeating a Bugster with them, as it wasn't that game's data the Bugster was born from.
 * Mighty Action X: Cleared by destroying the boss monster Salty.
 * Taddle Quest: Cleared by destroying the boss monster Aranbura.
 * Bang Bang Shooting: Cleared by destroying the boss monster Commander Revol.
 * Bakusou Bike: Cleared by defeating the boss monster Motors in a motorbike race; destroying him wasn't needed.
 * Gekitotsu Robots: Cleared by destroying the user, Collabos Bugster (Gekitotsu Robots), and most prominently, Gatton Bugster.
 * DoReMiFa Beat: Cleared by destroying the user, Collabos Bugster (DoReMiFa Beat). An alternative non-destructive method would be to make Poppy Pipopapo smile.
 * Giri Giri Chambara: Cleared by destroying the user, Collabos Bugster (Giri Giri Chambara), and most prominently, Kaiden Bugster.
 * Jet Combat: Cleared by destroying the user, Collabos Bugster (Jet Combat) and most promiently, Vernier Bugster.
 * Drago Knight Hunter Z: Cleared by destroying the user, Graphite.
 * Shakariki Sports: Cleared by defeating the user, Kamen Rider Genm and most prominently, Charlie Bugster. Genm being tied closely enough to clear this game by defeating him may be because he was the user of the Gashat.
 * Ju Ju Burger: Cleared by making the boss monster Burgermon happy by preparing a burger for him.
 * Ganbarizing: Cleared by defeating a duplicate of Kamen Rider Hibiki.

Stage Select
By pressing the button on the Kimewaza Slot Holder without any Gashat inserted in it, the gamer can choose one location from an offered list. This completely rewrites the Game Area, literally teleporting all participants to another battlefield, even pulling in people not present at the location where the function is triggered from. This could be used to expand the fighting area, as well as to protect the original location from being damaged. Clearing a game will return the players to their original location, and being blasted out of a transformation with enough power can "eject" individual players.
 * A modern, bright city.
 * A racetrack.
 * A dark city at night.
 * A blue sky.
 * A beach.
 * A lake surrounded by trees.
 * A millitary shooting area.
 * A scrapyard.
 * A forest.
 * A dried lake.
 * A town square.
 * A hangar.

Selectable Characters
After inserting a Rider Gashat, Riders select their armor from a spinning array of ten profile images, below ordered in counterclockwise as seen from above. It is possible that the forms the Rider could use are independent of the active Rider Gashat, and the gamer can choose his favorite character from the set list before the transformation begins, but this concept has yet to be explored onscreen and is thus unconfirmed. Kuroto Dan's Gamer Driver also comes with a unique selectable character located between Lazer Level 1 and the grayed Ex-Aid image, his character list in turn including only one blank silhouette image instead of two.
 * Ex-Aid Action Gamer Level 1
 * Also used to access Ex-Aid Maximum Gamer Level 99
 * Brave Quest Gamer Level 1
 * Also used to access Brave Fantasy Gamer Level 50
 * Snipe Shooting Gamer Level 1
 * Also used to access Snipe Simulation Gamer Level 50
 * Lazer Bike Gamer Level 1
 * Grayed Ex-Aid Action Gamer Level 1, yet to be used
 * May be intended to be Proto Ex-Aid, but differs from Genm because Genm uses a purple Proto Mighty Action X Gashat, while all other Proto Gashats are black, meaning this might be selected if a black Proto Mighty Action X Gashat (if it indeed exists) were used.
 * Proto Brave Quest Gamer Level 1, yet to be used
 * Proto Snipe Shooting Gamer Level 1, yet to be used
 * Proto Lazer Bike Gamer Level 1, yet to be used
 * Two generic silhouettes with question marks
 * The one next to the colored Ex-Aid changes into Ex-Aid Double Action Gamer Level X when Emu first transforms into said form. After being revealed, it appears in all Riders' available profiles (though it was missing by production error in several later episodes).
 * The same silhouette had previously changed into Ex-Aid Ghost Gamer Level 1, though it may be the case that any Legend Rider Gashat temporarily occupies one of the blank slots when used.
 * Genm Action Gamer Level 1
 * When Genm uses the Magic The Wizard Gashat, his list is missing Genm Action Gamer Level 1, instead including Genm Wizard Gamer Level 1 (showing Wizard himself instead of a Level 1 form) replacing the blank slot next to Ex-Aid.

Kimewaza Slot
By inserting a Rider Gashat into the Kimewaza Slot (it needs not be the Gashat used for the transformation), a Rider can trigger a Critical Strike finisher based on that Gashat after pressing the button next to the slot twice.

Of note, Genm inserting the Shakariki Sports Gashat into the Kimewaza Slot without pressing the button summoned the Sports Gamer bicycle in his initial debut.

History
The Gamer Drivers, along with the Rider Gashats, were created by Kuroto Dan, CEO of Genm Corp. as a countermeasure to the Bugsters after the occurrence of Zero Day.
