MSI Entertainment Plug & Plays
|MSI Entertainment Plug & Plays|
The MSI Entertainment Plug & Plays are...something. These somehow-licensed Famiclones only have one game per console, all originating from the NES/Famicom, and are priced at a rather high $20 each. They're not the worst of these kinds of consoles out there, but certainly the most barebones, and are triumphed by their older Y2K counterparts.
As each one is effectively based on the same code, all of the consoles will be documented on this page instead of separate pages for each game. Consoles analyzed include:
- Double Dragon
- Mega Man II
- Ms. Pac-Man
- Space Invaders
- WWF WrestleMania: Steel Cage Challenge
- Namco Classics Vol. 1 (feat. Dig Dug II, Pac-Mania, and The Tower of Druaga)
Mega Man II's controls are inversed when played in an emulator. Is this how the machine actually behaves, or is it an emulation glitch?
Controller and Checksum Test
A basic controller test with some Nice Code music, accessed by holding A + B while turning a console on. This doesn't seem to work on Space Invaders, despite it still being in the system's code.
Namco/Midway Classics Menu Graphics
Stored with the menu data of the 3-in-1 systems are giant sprites of Psy, of Gangnam Style fame. They are presumably left over from a bootleg plug & play.
In the same area is a flock of birds; quite angry ones. Their odd inclusion of shoes imply they are based on the NES "Angry Birds 2" bootleg, a hack of Kiwi Kraze.
Unknown VT-Based Graphics
CHR for an unknown game; its PRG does not seem to be present. It is overwritten in Double Dragon and Mega Man II.
Glitched Taito Logo
|When run as VT09||When run as VT03|
The Taito logo at the beginning of Space Invaders is in VT03 format despite the console itself being in VT09 format, causing its colors to display incorrectly. By running it as VT03, the correct colors will be shown.
Frogger Source Code
A chunk of source code can be found in Frogger at address 116000 (and duplicated several times throughout):

WWE Steel Cage Challenge
There were two releases of the unit, with production dates on the packaging of 082018 and 092018.
- The 082018 release is more polished, with new arrangements of Ultimate Warrior and Razor Ramon's entry music to go with their use as replacement characters. This carries a copyright date of 2018, and doesn't contain the Ms. Pac-Man code listed below as it has a 1MB Flash ROM.
- The 092018 release is more common, but has a 2017 copyright date and does not feature the entry themes for the new characters, just the original themes dummied out. This has a 2MB ROM, containing the unused Ms. Pac-Man code.
Reused Content and Other Oddities
- Space Invaders has the two-player mode intact by pressing Select (a button not present on the system itself), though it causes the graphics to glitch slightly.
- The WWF system has the entirety of the Ms. Pac-Man system as the first half of its coding.
- Ms. Pac-Man (and as such WWF) have leftover Taito copyrights from Space Invaders.
- The Midway Classics Vol. 1 and Namco Classics Vol. 1 seem to share the same coding, as all six games are intact. The menu system also seems to have every game incorporated. There is likely some way on the circuit board to change between the menus/game lists.
