Desert Storm is a Contra clone similar to Super Contra 7, made by Waixing possibly in 1996 or so. It's also featured on some Suborfamiclones, but is unknown if it was released as a single cart.
The gameplay is quite similar to other Contra games. It contains 4 stages, each divided into 2 sections (in levels 1, 2 and 4 there's a mid-boss between sections), and also boasts an option menu with a difficulty and number of lives (from 0 to 10) selector (if 0 is set as the starting lives, the player will automatically get a Game Over). Some graphics were lifted from Super Contra 7 and possibly from other Contra games, and even from another Konami game, Rush 'n Attack as well. It also features four different powerups: L is for Machine Gun, F is for Laser Gun, B is for Barrier and S is for Spread Gun, which is the default gun in this game. Also the powerup letters for the first two are incorrectly assigned (B and S being exceptions).
An alternate version of this game exists, which modifies the palette colors. It can be found on VT03 plug-&-play consoles (Sudoku 49-in-1 being an example).
The copyright number reads "960419". This means it was possibly released after Super Fight I, which has a copyright number of "960418".
The first miniboss of the second stage resembles Super Contra 7's first boss. There are also minor enemies flying around the level that resemble small variants of these bosses.
