Summary 06466: raycris: Soft resets during final boss fight
Description During the final boss fight, the game freezes (BGM and sound effect still plays) and soft-resets back to Taito G-Net boot screen after few seconds. This occurs when the encroachment level is below 20% upon reaching stage 5 (Self Field), thus makes reaching the true final boss (and good ending, subsequently) impossible. This bug doesn't occurs when "normal" ending condition is met by having encroachment level above 20% upon reaching stage 5 however. Save state isn't attached due to large size (10 megs after compression), so I uploaded it elsewhere:
Steps To Reproduce 1. Reach True Last Boss condition: get to stage 5 (Self Field) with Encroachment level below 20%
2. After several minute of normal final boss (Dis-Human) fight, the game freezes and soft-resets back to Taito G-Net screen. Usually occurs sometime when the boss is performing a double laser beam pattern for the second time as seen in the attachment
Additional Information It doesn't seem to be nvram-side issue, I've re-cleaned the nvram files and still getting the same result.

I'm able to confirm the reported behavior by using the supplied save state. It's really difficult to have the patience to play this game all the way through. Maybe someday...

This bug happens also when facing the final boss in the alternate way, by letting the Encroachment level go up to 100%. To do that, just don't shoot any enemy. In a few minutes the counter will reach the maximum and the boss will attack you.

This way, I can confirm the soft reset after a brief fight with the boss, using the 32-bit build and Windows XP SP3.

I can confirm the issue is still happening and the encroachment level doesn't matter at all. Knowing this makes future testing much more encouraging, cause keeping the encroachment below 20% during the whole game is nearly impossible.
The game still crashes and resets when the final boss does his super laser shot seen in the attached image.
