Bugfixes provided by Cristian Secara:
- In the original release, if a tape error occurs when loading a level, you cannot reload that level. Also the original levels have different lengths and, when loading certain levels in 128K mode, some bytes are lost.
- In level 1, pressing control keys simultaneously may crash the game.
- In level 2, if you drop a grenade inside a house in the village, you instantly appear outside the house and cannot continue playing.
- Both the original release and Hit Squad re-release are incompatible with +2A/+3.
- From the main screen, if you type "EQUINOXE" to enter cheat mode, the "CHEAT" message appears but nothing else changes. In the BUGFIX version, cheat mode works as follows:
1. The forest: infinite lives
2. The village: infinite lives
3. The tunnel system: infinite lives (also unlimited ammunition until the enemy soldier behind the table is killed)
4. Skirt by night: infinite lives
5. The 3D jungle: infinite lives and unlimited time
6. The bunker: infinite lives
