The arcade core: Batrider by Raizing, Toaplan2 core (github is closed), batrider_mister_20250330.rbf
Mister build: QMTech
Situation: I can't get to Stage 6 or later, 'cos the game logic (or 68000 CPU's logic, trying to get data from RAM which is missing) crashes, writing something like this on attached screenshot.
What I did:
- I checked SDRAM - 150 MHz for hour, zero errors (should I test it more)
- I have no issues with other heavy cores like 5th gen consoles
- I tried USA and JAP B versions of the game
- I checked fc/b binary files downloaded by update_all with my MAME copy - bit by bit equivalent
- It also crashes at attract mode over time (10-20 mins or more)
- I can play 5-stage mode completely and get the ending
- I'm having issues getting previous versions of the cores, cos toaplan's Github is closed and I can't google something a bit older to test

How to fix this?
Thanks for any input in advance.
