This is the version used for the Dreamcast port (released the 21/06/2012), even if it's written v1.0 on the title screen.

v1.2 Second update for MVS released in late 2012. This time the game owners had to request the update by themselves to NG:Dev.Team. It added a Sound Effect for bombs explosions (like in the Dreamcast version) and it fixed the game crash glitch due to an abusive Bouncing Blaster use.

This is also the version used for AES (Neo Geo, released the 25/04/2013).

Differences
MVS v1.2 and Neo Geo games are exactly the same, the only difference is about the credits system. On MVS you can insert as many credits as you want, but on AES you have only 4 credits inserted by default (which means 3 continues maximum). To balance that, collecting all the Big Diamonds in a stage on AES Original mode gives you 1 bonus credit.

The Dreamcast version has a few differences though:
 * the attract cutscene was a bit censored, the hero says "Your are cute!" instead of "Bitches!" (the typo is probably done on purpose to reproduce old Japanese games Engrish);
 * the third option on the Game Mode Selection screen leads to a setting menu where all the buttons can be mapped;
 * there is a button to enter/exit the Wheel mode directly (Down + Jump still works);
 * there aren't any falling leaves from the trees anymore;
 * the credits system is the same as the AES one, only 3 continues and 1 bonus credit if all Big Diamonds are collected in a stage on Original mode.
