Summary	09089: gondou: Gondomania 2P Crashes
Description	Hello, I have been attempting to get a full playthrough of Gondomania in and have had the game fully crash on me every single time across about a dozen attempts. The crashing seems to happen most often when there is a lot of sprite action occurring on the screen. Normally when the red swirl weapon is used, or the bike with the wave spray attack.
Steps To Reproduce	Load into gondou rom Play game for a while, get the red swirly weapon if possible Eventually along the way the game will crash, usually when the gondola ship enemies come onto screen or get destroyed.
Additional Information	Video of some of the crashing here: The first clip has a full error that comes out at the end: https://imgur.com/a/yce79fB

Music still played slowly. The error log just showed heaps of unmapped reads and writes, and was 714MB in size. Appears that it ran into the weeds.

Recorded entire run available here: crash is at the end and timestamped in video Also it occurs when one of the gondola (enemy carrier ships) gets destroyed, which we have noticed precedes a crash frequently (though not all the time)
No.22860 Robbbert Moderator 2 days ago	I've confirmed that there is a problem, soon after the blue bird boss. The memory_bank message seems to be optional, as I never received it.
No.22861 Ellimist Tester 2 days ago	I only got the memory bank item one crash out of the dozen or so. I included it because it was the most detailed error I got. Most of the time things just froze with a weird sprite pattern or repeating background corruption. May not be relevant.
