Rocman X

Rocman X (also known as Thunder Blast Man) is an unlicensed game created by Sachen, released on the Famicom and NES sometime in the 90's and also sometime later for the Game Boy Color. The NES and English Game Boy Color versions were released as Thunder Blast Man, the Chinese version of the GBC game released as Rockman X Gold, and one of the NES versions' label calls it Thunder Blaster Man.

Rocman X's title screen is mostly copied from the first Famicom game of Rocman's, with the logo taken from Rocman X. The game also includes a story in English where Gadem City celebrates its centennial before the mayor's daughter, Miss Lucy, is kidnapped by the Paulung-Tang gang, who then take over and sabotage the city, holding it for a $20 billion ransom. Thunder Blast Man himself (also commonly known as Rocman X) appears to be based on Rocman/Mega Man and bears a passing resemblance to Quickman from Mega Man 2, as well as sporting a cape. His default weapon is a boomerang as opposed to a standard Mega Buster, and only one can be thrown on screen at a time. You can get different weapons as well as buy a spare continue (if you don't have one) by visiting stores located before boss fights in each world, save for the motorcycle stage. As well as this, Thunder Blast Man has a charge move triggered by holding B and, after it fully charges (designated by the health bar flashing) releasing it while holding up, left, or right to fly in that direction (releasing it while being still cancels the move.) This allows him to get across many pits throughout the game.

The first three areas are available on the stage select screen, and most stages (save for the fourth area, where the boss is fought at the end of a single motorbike area) are split into two parts and a boss each. After clearing these, the game becomes linear as you access the last three areas automatically in order. The fourth area is a motorbike chase scene which looks and plays somewhat similarly to the speedboat sequence towards the end of Wave Man's stage in Mega Man 5. If you die in a stage you can continue from the point that you left off at (assuming you have a continue; you always start a new game with a continue) but if you used it up or don't have one you have to restart at the stage you're currently on, losing your bought weapons in the process. This is a bit different in the mine cart segment of the final world, as falling into the spikes give you a game over regardless of health or continues, but you restart the level with your on-hand items (spare continue and/or weapons) intact. The ending explains that Thunder Blast Man has saved Gadem City from the Paulung-Tang gang and that the city has made a statue of him.
