［Arcade］GunNail location test （NMK 1992）1-ALL

Player:SLK（2024-05-06 22-00-35）OBS
One of the classic arcade shooting games released by Japan's NMK company in 1992, in addition to beautiful graphics and beautiful music, it also has a very special game system. If you want to achieve high scores, you need to consume HP to the lowest at the beginning of each level to obtain the maximum score multiplier. The maximum enemy multiplier is x10, and the maximum boss multiplier is x100. Therefore, pursuing high score clearance games is a very tense and exciting challenge. This version is a special early location test version, with an opening animation of a ray shooting towards the ground and exploding. The stage order and enemy configuration of the game are very different from the final version, such as the ocean and space levels, with many different enemies and background materials, but these things have been removed in the final version. In 2019, an arcade enthusiast purchased this version of the PCB and contributed it to the MAME team. In the MAME 0.218 version released on February 2, 2020, this version was officially supported, and its preservation is also of great significance.
This version has only 7 stages as it has not been completed yet. After passing the 7th level, it enters 2Loop and will loop endlessly thereafter.
