Salamander Portable is a compilation that contains ports of five arcade shooters from Konami:
- Life Force (updated Japanese version)
- Gradius 2 (MSX version)
- Salamander
- Salamander 2
- Xexex
The MSX version of Gradius 2 (aka Nemesis 2) is included in two variants, an Enhanced version (default) with smooth scroll and updated graphics, or the original version. In addition the games settings menu has an option to select if a second Konami cartridge is present. Just like with the original game this has certain effects, such as cheats or changed visuals.
